Subject: [DO NOT MERGE] [PATCH v2 3/3] arm64: rockchip: rk3399: nanopc-t4: Enable FriendlyELEC HD702E eDP panel
Date: Tue,  7 May 2019 18:37:08 +0530	[thread overview]
Message-ID: <20190507130708.11255-3-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190507130708.11255-1-jagan@amarulasolutions.com>

FriendlyELEC HD702E is one of optional LCD panel for
NanoPC T4 eDP interface.

It features 800x1280 resolutions, with built in GT9271 captive
touchscreen and adjustable backlight via PWM.

eDP panel connections are:
- VCC3V3_SYS: 3.3V panel power supply
- GPIO4_C2: PWM0_BL pin
- GPIO4_D5_LCD_BL_EN: Backlight enable pin
- VCC12V0_SYS: 12V backlight power supply
- Touchscreen connected via I2C4
- GPIO1_C4_TP_INT: touchscreen interrupt pin
- GPIO1_B5_TP_RST: touchscreen reset pin

Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

Changes for v2:
- use force-hpd and delete-property for edp
- use generic backlight brightness
- add simple-panel fallback compatible
