2011-05-23sh_mobile_meram: MERAM framework for LCDCDamian
Based on the patch by Takanari Hayama <taki@igel.co.jp> Adds support framework necessary to use Media RAM (MERAM) caching functionality with the LCDC. The MERAM is accessed through up to 4 Interconnect Buffers (ICBs). ICB numbers and MERAM address ranges to use are specified in by filling in the .meram_cfg member of the LCDC platform data Signed-off-by: Damian Hobson-Garcia <dhobsong@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2011-03-29fbdev: sh_mobile_lcdcfb: add blanking supportAlexandre Courbot
Add a blanking callback to the LCDC driver in order to support both FBIOBLANK and TIOCLINUX blanking ioctls. LCDC clocks are also released if the requested blanking level is superior to FB_BLANK_NORMAL, to allow runtime PM to disable the clocks if possible.

2011-03-16fbdev: sh_mobile_lcdc: Add YUV framebuffer supportDamian Hobson-Garcia
Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats (bpp = 12, 16, and 24) respectively. When double-buffering both Y planes appear before the C planes (Y-Y-C-C), as opposed to Y-C-Y-C. Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use .bpp to distiguish between the 3 modes. The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and should be set accordingly. .nonstd must be set to 0 for RGB mode. Due to the encoding of YUV data, the framebuffer will clear to green instead of black. In YUV 420 mode, panning is only possible in 2 line increments. Additionally in YUV 420 mode the vertical resolution of the framebuffer must be an even number.

2011-03-10fbdev: sh_mobile_lcdcfb: add backlight supportAlexandre Courbot
Support for backlight devices controlled through board-specific routines. Backlights can be defined per-channel and follow fbdev directives to switch off as the LCD blanks or is turned on/off. Signed-off-by: Alexandre Courbot <gnurou@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-09-16fbdev: sh_mobile_lcdc: reconfigure the framebuffer, when freeGuennadi Liakhovetski
Currently the sh_mobile_lcdc driver only reconfigures the hardware interface, when a new monitor is plugged in. This patch adds support for dynamic framebuffer reconfiguration, when no user is holding the framebuffer device node open.

2010-09-14fbdev: sh_mobile_lcdcfb: separate display variable data from framebuffer dataGuennadi Liakhovetski
This is a preparation for a patch, that shall allow displaying of a smaller framebuffer on a bigger display and of a part of a bigger framebuffer on a smaller display. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-09-14fbdev: sh_mobile_hdmi: implement lockingGuennadi Liakhovetski
The SH-Mobile HDMI driver runs in several contexts: ISR, delayed work-queue, task context, when called from the sh_mobile_lcdc framebuffer driver. This creates ample race possibilities. Even though most these races are purely theoretical, it is better to close them. To trace fb_info validity we install a notification callback in the HDMI driver, and the only way for it to get to driver internal data is by using struct sh_mobile_lcdc_chan, therefore it had to be extracted into a separate common header.
