Subject: [PATCH 04/18] arm64: dts: rk3399-pinephone-pro: Fix goodix
|
|
toucscreen interrupts
|
|
|
|
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'.
|
