Subject: [PATCH v10 08/11] arm64: dts: rockchip: Add eDP node for RK3576

From: Damon Ding <[email-masked]>
Date: Mon, 1 Jun 2026 14:50:57 +0800

Add full device tree definition for the integrated eDP controller
on RK3576, following the existing RK3588 hardware layout.

Configure required register range, clocks, interrupt, phy, power
domain, reset and grf properties to fully describe the controller.
