Subject: [PATCH v5 20/20] arm64: dts: rockchip: Enable eDP0 display on RK3588S EVB1 board
Date: Thu,  9 Jan 2025 11:27:25 +0800	[thread overview]
Message-ID: <20250109032725.1102465-21-damon.ding@rock-chips.com> (raw)
In-Reply-To: <20250109032725.1102465-1-damon.ding@rock-chips.com>

Add the necessary DT changes to enable eDP0 on RK3588S EVB1 board:
- Set pinctrl of pwm12 for backlight
- Enable edp0/hdptxphy0/vp2
- Add aux-bus/panel nodes

Signed-off-by: Damon Ding <damon.ding@rock-chips.com>

---

Changes in v2:
- Remove brightness-levels and default-brightness-level properties in
  backlight node.
- Add the detail DT changes to commit message.

Changes in v3:
- Use aux-bus instead of platform bus for edp-panel.

Changes in v4:
- Add comments related to the use of panel compatible "lg,lp079qx1-sp0v"
  in the commit message.

Changes in v5:
- Use "edp-panel" instead of "lg,lp079qx1-sp0v"
- Remove unnecessary comments in commit message
- Assign the parent of DCLK_VOP2_SRC to PLL_V0PLL
