Subject: [PATCH] arm64: dts: rockchip: Drop data-mapping from Engicam PX30 Core
Date: Mon, 27 Jul 2026 14:55:02 -0300	[thread overview]
Message-ID: <20260727175502.2585290-1-festevam@gmail.com> (raw)

The panel-simple schema only allows data-mapping overrides for panels
whose mapping is not fixed by their compatible. Consequently, the property
on the Ampire AM-1280800N3TZQW-T00H panel fails validation:

(ampire,am-1280800n3tzqw-t00h): False schema does not allow ['vesa-24']

The panel descriptor already selects 8 bits per color and
MEDIA_BUS_FMT_RGB888_1X7X4_SPWG. The DRM OF helpers translate
"vesa-24" to that exact bus format, and panel-simple falls back to the
descriptor's format when the property is absent. Removing the property
therefore has no functional effect.

Drop the redundant property to satisfy the binding.
