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.

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)

Bandwidth can be less than requested in some cases, because the search

This is likely not intentional.

Subject: [PATCH 10/36] video: fbdev: Add events for early fb event support
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.

Subject: [PATCH 35/36] usb: typec: typec-extcon: Add typec -> extcon bridge
driver
This bridge connects standard Type C port interfaces for controling
muxes, switches and usb roles to muxes, switches and usb role
drivers controlled via extcon interface.

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 093/194] media: ov5640: Sleep after poweroff to ensure next
poweron is not too early
It's easy to use v4l2 userspace api in such a way that user can trigger
a brownout on the sensor instead of a proper powerdown and powerup.

Subject: [PATCH 094/194] media: ov5640: Don't powerup the sensor during
driver probe
It causes autofocus clicking during boot on some devices, and
it's enough to do it when turning on the sensor power by media
pipeline via s_power callback, later on.

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.

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.

The interrupt type read from the screen does not work well. It generates
constant stream of interrupts.
Change to rising edge interrupt, and enforce it in the driver via
'use-dt-irq-flags'.

Subject: [PATCH 09/18] arm64: dts: rk3399-pinephone-pro: Correct the battery
specification
MIME-Version: 1.0
Content-Type: text/plain; charset="utf-8"
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).

reasonable
Let's not overtax the battery and provide only 4.5W to external devices.
Even that may be too much, given what PPP can consume by itself.

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.
