From 6ca8d2c068bb5c6116396cde2cc7a2f4836df212 Mon Sep 17 00:00:00 2001 From: Michael Tretter Date: Fri, 13 Oct 2023 13:00:22 +0200 Subject: [PATCH] media: rockchip: rga: fix swizzling for RGB formats [ Upstream commit 9e7dc39260edac180c206bb6149595a40eabae3e ] When using 32 bit RGB formats, the RGA on the rk3568 produces wrong colors as the wrong color channels are read or written. The reason is that the format description for the channel swizzeling is wrong and the wrong bits are configured. For example, when converting ARGB32 to NV12, the alpha channel is used as blue channel.. This doesn't happen if the color format is the same on both sides. Fix the color_swap settings of the formats to correctly handle 32 bit RGB formats. For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus, it is removed from the list of supported formats.
