2022-12-16mb/google/geralt: Pass GPIOs to allow backlight control in payloadsBo-Chen Chen
There are two ways to control backlight in geralt: 1. MIPI/eDP panel => control backlight via the GPIOs. (`backlight chip enable` and `PWM dimming control`) 2. eDP OLED panel => enable backlight via `backlight chip enable` and control dimming over AUX. For MIPI/eDP panels(#1), both "backlight enable" and "PWM control" GPIOs will be passed from coreboot. For eDP OLED panel(#2), only the "backlight enable" GPIO will be passed. If depthcharge successfully gets the GPIOs, it will use them to control backlight. BUG=b:244208960 TEST=test firmware display pass for eDP and MIPI panels on MT8188 EVB Change-Id: I866fa219722241008e2b0d566b29edf2f6d9321f Signed-off-by: Bo-Chen Chen <rex-bc.chen@mediatek.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/70744 Reviewed-by: Yidi Lin <yidilin@google.com> Reviewed-by: Yu-Ping Wu <yupingso@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
