Subject: [PATCH 0/1] sh_mobile_lcdc: Add NV12 input framebuffer support
Date: Tue, 15 Feb 2011 01:51:47 +0000	[thread overview]
Message-ID: <1297734708-20803-1-git-send-email-dhobsong@igel.co.jp> (raw)

These patches add initial support for YUV 4:2:0 (NV12) framebuffer input for the
LCDC.

Due to the encoding of the NV12 color format, writing 0s to the entire
framebuffer memory area produces a green, rather than a black screen.

Specifying .bpp = 12 and .yuv = 1 when configuring the LCDC channel will enable
NV12 input support.

  Add NV12 input support for framebuffer
