[PATCH 0/2] media: rppx1: parameters block fixes
From: Linmao Li
Date: Mon Aug 17 2026 - 06:48:43 EST
Fix two issues in the RPP-X1 parameters path.
Patch 1 adds the missing type entry and dispatch for the MAIN_POST
white balance gains block. Without them, userspace cannot configure
the module. The zero-sized block this hole exposes in the common
validator is handled by a pending v4l2-isp patch.
Patch 2 fixes the Bayer pattern source used by PRE2 black level
compensation. The PRE2 path is not enabled yet, so this is a latent
fix.
The series is based on media-committers next at 31152f5b0f87.
Compile tested with allmodconfig. W=1 builds of drivers/media/v4l2-core,
drivers/media/platform/dreamchip and
drivers/media/platform/renesas/rcar-isp were clean before and after the
series. I have no RPP-X1 hardware, so neither patch is runtime tested.
