Subject: [PATCH v2] arm64: dts: rockchip: Enable DisplayPort for rk3588-evb2
Date: Thu, 18 Sep 2025 14:28:25 +0800	[thread overview]
Message-ID: <20250918062825.194-1-kernel@airkyi.com> (raw)

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

The rk3588 evb2 board has a full size DisplayPort connector, enable
for it.

Signed-off-by: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Changes in v2:

- Link to V1: https://lore.kernel.org/all/20250916080802.125-1-kernel@airkyi.com/
- Fix invalid DP connector type
- Add more comment about dclk_vp2 parent clock
