Subject: [PATCH v14 15/28] drm/rockchip: Add YUV422 output mode constants for VOP2

From: Nicolas Frattaroli <[email-masked]>
Date: Thu, 23 Apr 2026 21:03:38 +0200

The Rockchip display controller has a general YUV422 output mode, and
some SoC-specific connector-specific output modes for RK3576.

Add them, based on the values in downstream and the TRM (dsp_out_mode in
RK3576 TRM Part 2, register POST*_CTRL_POST_DSP_CTRL).
