Subject: [PATCH v2 12/18] OMAPDSS: DISPC: Don't set chroma resampling bit for writeback
Date: Tue, 25 Sep 2012 06:31:47 +0000 [thread overview]
Message-ID: <1348553993-8083-13-git-send-email-archit@ti.com> (raw)
In-Reply-To: <1348553993-8083-1-git-send-email-archit@ti.com>
The bit YUVCHROMARESAMPLING isn't there for writeback in DISPC_WB_ATTRIBUTES2.
It isn't there because we don't upsample chroma like for video pipelines, we
downsample chroma in writeback to get YUV422 or NV12 formats from the YUV444
input.
Ignore this bit in dispc_ovl_set_scaling_uv() if the plane is OMAP_DSS_WB.
