Subject: [PATCH 0/2] fbdev: sh_mobile_lcdc: YUV framebuffer support
Date: Wed, 23 Feb 2011 10:16:48 +0000 [thread overview]
Message-ID: <1298456210-26519-1-git-send-email-dhobsong@igel.co.jp> (raw)
These patches add support for 12, 16, and 24 bit YUV framebuffers.
These patches are a reworking of an earlier submitted patch
"Add NV12 input framebuffer support" to include the two other modes.
Additionally updated are:
* Y and C plane ordering. When double-buffering both Y planes appear before
the C planes (Y-Y-C-C), instead of Y-C-Y-C.
* In YUV 420 mode, panning is only possible in 2 line increments
* Additionally in YUV 420 mode the value of yres must be set to an even number
* The value of .nonstd in struct sh_mobile_lcdc_chan_cfg from the platform data is
exposed to applications via the .nonstd element of struct fb_var_screeninfo.
Additionally this value is written to bits 16-31 of LDDFR in the LCDC.
* Chip dependent flags for the bits of LDDFR greater that bit 17 are defined
* Add a userspace include file <linux/sh_mobile_fb.h> as a place to hold defines
and future ioctl definitions.
