From: Ondrej Jirman <megous@megous.com>
Date: Mon, 15 Nov 2021 04:09:50 +0100
Subject: [PATCH 01/36] base: property: Swap order of search for connection to
"devcon, graph"
This avoids confusing error in kernel log, when using devcon matching
in DT. Example:
"OF: graph: no port node found in /i2c@ff3d0000/typec-portc@22"
This suggest there's some error because graph based search failed,
but there is no error, because devcon based matching succeeds.

+ This option enables the Linux bootsplash screen.
+
+ The bootsplash is a full-screen logo or animation indicating a
+ booting system. It replaces the classic scrolling text with a
+ graphical alternative, similar to other systems.
+
+ Since this is technically implemented as a hook on top of fbcon,
+ it can only work if the FRAMEBUFFER_CONSOLE is enabled and a
+ framebuffer driver is active. Thus, to get a text-free boot,
+ the system needs to boot with vesafb, efifb, or similar.
+
+ Once built into the kernel, the bootsplash needs to be enabled
+ with bootsplash.enabled=1 and a splash file needs to be supplied.
+
+ Further documentation can be found in:
+ Documentation/fb/bootsplash.txt
+
+ If unsure, say N.
+ This is typically used by distributors and system integrators.

Date: Sun, 21 Nov 2021 17:00:09 +0100
Subject: [PATCH 24/36] media: rockchip: rga: Fix probe bugs
The check for dst_mmu_pages allocation failure was inverted.
rga_parse_dt is missing a error return, so if some of the resources
return DEFER_PROBE, probe will succeed without these resources.

Subject: [PATCH 04/36] drm: bridge: dw-mipi-dsi: Fix enable/disable of dsi
controller
The driver had it all wrong. mode_set is not for enabling the
DSI controller, that should be done in pre_enable so that
panel driver can initialize the panel (working dsi controller
is needed for that). Having dsi powerup in mode_set led to
all kind of fun, because disable would be called more often
than mode_set.
The whole panel/dsi enable/disable dance is such (for future
reference):
- dsi: mode set
- panel: prepare (we turn on panel power)
- dsi: pre enable (we enable and setup DSI)
- dsi: enable (we enable video data)
- panel: enable (we configure and turn on the display)
For disable:
- panel: disable (we turn off the display nicely)
- dsi: disable (we disable DSI)
- dsi: post disable
- panel: unprepare (we power off display power, panel should
be safely sleeping now)

Subject: [PATCH 07/36] drm: dw-mipi-dsi-rockchip: Never allow lane bandwidth

Bandwidth can be less than requested in some cases, because the search
for best values only checked for absolute difference from ideal value.
This is likely not intentional.

+====================
+The Linux bootsplash
+====================
+
+:Date: November, 2017
+:Author: Max Staudt <mstaudt@suse.de>
+
+
+The Linux bootsplash is a graphical replacement for the '``quiet``' boot
+option, typically showing a logo and a spinner animation as the system starts.
+
+Currently, it is a part of the Framebuffer Console support, and can be found
+as ``CONFIG_BOOTSPLASH`` in the kernel configuration. This means that as long
+as it is enabled, it hijacks fbcon's output and draws a splash screen instead.
+
+Purely compiling in the bootsplash will not render it functional - to actually
+render a splash, you will also need a splash theme file. See the example
+utility and script in ``tools/bootsplash`` for a live demo.
+
+
+
+Motivation
+==========
+
+- The '``quiet``' boot option only suppresses most messages during boot, but
+ errors are still shown.
+
+- A user space implementation can only show a logo once user space has been
+ initialized far enough to allow this. A kernel splash can display a splash
+ immediately as soon as fbcon can be displayed.
+
+- Implementing a splash screen in user space (e.g. Plymouth) is problematic
+ due to resource conflicts.
+
+ For example, if Plymouth is keeping ``/dev/fb0`` (provided via vesafb/efifb)
+ open, then most DRM drivers can't replace it because the address space is
+ still busy - thus leading to a VRAM reservation error.
+
+ See: https://bugzilla.opensuse.org/show_bug.cgi?id=980750
+
+
+
+Command line arguments
+======================
+
+``bootsplash.bootfile``
+ Which file in the initramfs to load.
+
+ The splash theme is loaded via request_firmware(), thus to load
+ ``/lib/firmware/bootsplash/mytheme`` pass the command line:
+
+ ``bootsplash.bootfile=bootsplash/mytheme``
+
+ Note: The splash file *has to be* in the initramfs, as it needs to be
+ available when the splash is initialized early on.
+
+ Default: none, i.e. a non-functional splash, falling back to showing text.
+
+
+
+sysfs run-time configuration
+============================
+
+``/sys/devices/platform/bootsplash.0/enabled``
+ Enable/disable the bootsplash.
+ The system boots with this set to 1, but will not show a splash unless
+ a splash theme file is also loaded.
+
+
+
+Kconfig
+=======
+
+``BOOTSPLASH``
+ Whether to compile in bootsplash support
+ (depends on fbcon compiled in, i.e. ``FRAMEBUFFER_CONSOLE=y``)
+
+
+
+Bootsplash file format
+======================
+
+A file specified in the kernel configuration as ``CONFIG_BOOTSPLASH_FILE``
+or specified on the command line as ``bootsplash.bootfile`` will be loaded
+and displayed as soon as fbcon is initialized.
+
+
+Main blocks
+-----------
+
+There are 3 main blocks in each file:
+
+ - one File header
+ - n Picture headers
+ - m (Blob header + payload) blocks
+
+
+Structures
+----------
+
+The on-disk structures are defined in
+``drivers/video/fbdev/core/bootsplash_file.h`` and represent these blocks:
+
+ - ``struct splash_file_header``
+
+ Represents the file header, with splash-wide information including:
+
+ - The magic string "``Linux bootsplash``" on big-endian platforms
+ (the reverse on little endian)
+ - The file format version (for incompatible updates, hopefully never)
+ - The background color
+ - Number of picture and blob blocks
+ - Animation speed (we only allow one delay for all animations)
+
+ The file header is followed by the first picture header.
+
+
+ - ``struct splash_picture_header``
+
+ Represents an object (picture) drawn on screen, including its immutable
+ properties:
+ - Width, height
+ - Positioning relative to screen corners or in the center
+ - Animation, if any
+ - Animation type
+ - Number of blobs
+
+ The picture header is followed by another picture header, up until n
+ picture headers (as defined in the file header) have been read. Then,
+ the (blob header, payload) pairs follow.
+
+
+ - ``struct splash_blob_header``
+ (followed by payload)
+
+ Represents one raw data stream. So far, only picture data is defined.
+
+ The blob header is followed by a payload, then padding to n*16 bytes,
+ then (if further blobs are defined in the file header) a further blob
+ header.
+
+
+Alignment
+---------
+
+The bootsplash file is designed to be loaded into memory as-is.
+
+All structures are a multiple of 16 bytes long, all elements therein are
+aligned to multiples of their length, and the payloads are always padded
+up to multiples of 16 bytes. This is to allow aligned accesses in all
+cases while still simply mapping the structures over an in-memory copy of
+the bootsplash file.
+
+
+Further information
+-------------------
+
+Please see ``drivers/video/fbdev/core/bootsplash_file.h`` for further
+details and possible values in the file.
+
+
+
+Hooks - how the bootsplash is integrated
+========================================
+
+``drivers/video/fbdev/core/fbcon.c``
+ ``fbcon_init()`` calls ``bootsplash_init()``, which loads the default
+ bootsplash file or the one specified on the kernel command line.
+
+ ``fbcon_switch()`` draws the bootsplash when it's active, and is also
+ one of the callers of ``set_blitting_type()``.
+
+ ``set_blitting_type()`` calls ``fbcon_set_dummyops()`` when the
+ bootsplash is active, overriding the text rendering functions.
+
+ ``fbcon_cursor()`` will call ``bootsplash_disable()`` when an oops is
+ being printed in order to make a kernel panic visible.
+
+``drivers/video/fbdev/core/dummyblit.c``
+ This contains the dummy text rendering functions used to suppress text
+ output while the bootsplash is shown.
+
+``drivers/tty/vt/keyboard.c``
+ ``kbd_keycode()`` can call ``bootsplash_disable()`` when the user
+ presses ESC or F1-F12 (changing VT). This is to provide a built-in way
+ of disabling the splash manually at any time.
+
+
+
+FAQ: Frequently Asked Questions
+===============================
+
+I want to see the log! How do I show the log?
+---------------------------------------------
+
+Press ESC while the splash is shown, or remove the ``bootsplash.bootfile``
+parameter from the kernel cmdline. Without that parameter, the bootsplash
+will boot disabled.
+
+
+Why use FB instead of modern DRM/KMS?
+-------------------------------------
+
+This is a semantic problem:
+ - What memory to draw the splash to?
+ - And what mode will the screen be set to?
+
+Using the fbdev emulation solves these issues.
+
+Let's start from a bare KMS system, without fbcon, and without fbdev
+emulation. In this case, as long as userspace doesn't open the KMS
+device, the state of the screen is undefined. No framebuffer is
+allocated in video RAM, and no particular mode is set.
+
+In this case, we'd have to allocate a framebuffer to show the splash,
+and set our mode ourselves. This either wastes a screenful of video RAM
+if the splash is to co-exist with the userspace program's own allocated
+framebuffer, or there is a flicker as we deactivate and delete the
+bootsplash's framebuffer and hand control over to userspace. Since we
+may set a different mode than userspace, we'd also have flicker due
+to mode switching.
+
+This logic is already contained in every KMS driver that performs fbdev
+emulation. So we might as well use that. And the correct API to do so is
+fbdev. Plus, we get compatibility with old, pure fbdev drivers for free.
+With the fbdev emulation, there is *always* a well-defined framebuffer
+to draw on. And the selection of mode has already been done by the
+graphics driver, so we don't need to reinvent that wheel, either.
+Finally, if userspace decides to use /dev/fbX, we don't have to worry
+about wasting video RAM, either.
+
+
+Why is the bootsplash integrated in fbcon?
+------------------------------------------
+
+Right now, the bootsplash is drawn from within fbcon, as this allows us
+to easily know *when* to draw - i.e. when we're safe from fbcon and
+userspace drawing all over our beautiful splash logo.
+
+Separating them is not easy - see the to-do list below.
+
+
+
+TO DO list for future development
+=================================
+
+Second enable/disable switch for the system
+-------------------------------------------
+
+It may be helpful to differentiate between the system and the user
+switching off the bootsplash. Thus, the system may make it disappear and
+reappear e.g. for a password prompt, yet once the user has pressed ESC,
+it could stay gone.
+
+
+Fix buggy DRM/KMS drivers
+-------------------------
+
+Currently, the splash code manually checks for fbdev emulation provided by
+the ast, cirrus, and mgag200 DRM/KMS drivers.
+These drivers use a manual mechanism similar to deferred I/O for their FB
+emulation, and thus need to be manually flushed onto the screen in the same
+way.
+
+This may be improved upon in several ways:
+
+1. Changing these drivers to expose the fbdev BO's memory directly, like
+ bochsdrmfb does.
+2. Creating a new fb_ops->fb_flush() API to allow the kernel to flush the
+ framebuffer once the bootsplash has been drawn into it.
+
+
+Separating from fbcon
+---------------------
+
+Separating these two components would yield independence from fbcon being
+compiled into the kernel, and thus lowering code size in embedded
+applications.
+
+To do this cleanly will involve a clean separation of users of an FB device
+within the kernel, i.e. fbcon, bootsplash, and userspace. Right now, the
+legacy fbcon code and VT code co-operate to switch between fbcon and
+userspace (by setting the VT into KD_GRAPHICS mode). Installing a muxer
+between these components ensues refactoring of old code and checking for
+correct locking.

This patch adds FB_EARLY_EVENT_BLANK and FB_R_EARLY_EVENT_BLANK
event mode supports. first, fb_notifier_call_chain() is called with
FB_EARLY_EVENT_BLANK and fb_blank() of specific fb driver is called
and then fb_notifier_call_chain() is called with FB_EVENT_BLANK again
at fb_blank(). and if fb_blank() was failed then fb_nitifier_call_chain()
would be called with FB_R_EARLY_EVENT_BLANK to revert the previous effects.

Subject: [PATCH 14/36] power: supply: core: Don't ignore max_current of 0
when setting current limit
If we ignore current limit of 0, the dependent power source will not
set input current limit to that value when the supplier changes max
current to 0. This may happen when USB power is disconnected from the
device.
On next connection, the dependent power supply will start consuming
power at the previously set limit even before the PD/BC1.2 power
negotiation has a chance to complete.

It's possible to create a dependency cycle between fusb302 and
other drivers via extcon device, so we retrieve the device on
demand after probe and not during probe.

Subject: [PATCH 36/36] phy: rockchip-typec: Make sure the plug orientation is
respected
RK3399 TRM says about bit 8:
typec_conn_dir_sel: TypeC connect direction select
- 0: select typec_conn_dir (bit0 of this register) to TypeC PHY
- 1: select TCPC ouput typec_con_dir to TypeC PHY (default value)
This means that by default, typec_conn_dir bit is not respected.
Fix setting of typec_conn_dir by setting typec_conn_dir to 0 first.

Subject: [PATCH 120/194] media: ov5640: Implement autofocus
The autofocus functionality needs a firmware blob loaded into the
internal microcontroller.
V4L2 doesn't have an api to control all autofocus functionality, but
this at least makes it possible to focus on the center of the sensor.

Subject: [PATCH 06/36] drm: panel: hx8394: Improve the panel driver (make it
work with DSI fixes)
Powerup/down should be done in prepare/unprepare. Enable/disable is just
for initialization. Fix timings and reset order according to datasheet.
Reset panel on probe.

The actual rate that was set by CRU was 66.333 MHz The panel does
not actually work at 69 MHz, now that CRU can generate the requested
clock rate precisely.
Change the clock rate.

Subject: input: goodix: Add option to power off the controller during suspend
For whatever reason the controller is not suspended on Pinephone
by the default procedure. It consumes quite a bit of power (~40mW)
during system sleep, and more when the screen is touched.
Let's power off the controller during system sleep instead.

Subject: input: goodix: Don't disable regulators during suspend
It does no harm to disable them, but on Pinephone we have other
peripherals attached to the same power supplies, whose drivers
will not reference the regulator, so powering down the regulators
from Goodix driver will break those other devices.
Until those drivers gain the regulator support, don't disable
the regulators in Goodix driver.

Subject: [PATCH 06/18] arm64: dts: rk3399-pinephone-pro: Power off goodix
touchscreen in sleep
Otherwise it consumes 200mW of power when touched during system sleep.
It can't wake up the phone anyway.

Content-Transfer-Encoding: 8bit
XLS with ZCV measurements from the manufacturer say that at 25°C,
ZCV is ~200 mOhm. At 50°C it's at ~100 mOhm. Set some value in between.
Lower the charging current to something less aggressive.
Fix the current sensing resitor value (it's 10 mOhm in the schematic).

Subject: [PATCH 16/18] arm64: dts: rk3399-pinephone-pro: Use DCLK_VOP*_FRAC
to achieve precise rates
By setting parents of DCLK_VOP1_DIV to frac/cpll we can achieve
various clock rates needed by display engine precisely.

Subject: arm64: dts: rk3399-pinephone-pro: Add flash and fix leds
The PinePhone Pro has a similar device to the SGM3140 used in the OG
PinePhone. This commit adds the corresponding device-tree node so the
flash/torch can work on this device.
Moreover, existing LEDs use different names and functions than what
we're used to, change them all to the same names we use on the OG
PinePhone.

Subject: arm64: dts: rk3399-pinephone-pro: improve sound device definition
This commit renames the sound card and the "Headphone" widget so they
match the names used by the ALSA UCM profiles.
It also adds a jack detection GPIO to the sound card definition, and
creates a new set of ADC keys for handling headset buttons.
