1d3c6c7b36 davinci: fb : add suspend/resume suuport for DA8xx/OMAP-L1xx fb driver
Suspend/resume support DA8xx/OMAP-L1xx frame buffer driver.  This feature
has been tested on DA850/OMAP-L138 EVM.  For the purpose of testing, the
patch series[1] which adds suspend support for DA850/OMAP-L138 SoC was
applied.

3611380490 davinci: fb: update the driver in preparation for addition of power management features
Add a helper function to enable raster.  Also add one member in the
private data structure to track the current blank status, another function
pointer which takes in the platform specific callback function to control
panel power.

These updates will help in adding suspend/resume and frame buffer blank
operation features.

8097b1749f davinci: fb: calculate the clock divider from pixel clock info
The clock divider value can be calculated from the pixel clock value for
the panel.  This gives more flexiblity to the driver to change the divider
value on the fly as in the case of cpufreq feature- support for which will
be added shortly.

3510b8f7f5 davinci: fb: fix frame buffer driver issues
Following issues have been addressed on DA8XX/OMAP-L1XX:

a. Screen misalignment during booting when frame buffer console is
   enabled.

b. Driver was configured always in PSEUDOCOLOR mode.  This patch
   dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
   mode depending on bpp.

c. The RED and BLUE offsets were interchanged resulting in wrong
   bootup logo colour.

This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.

4ed824d9ae davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx
Add LCD controller (LCDC) driver for TI's DA8xx/OMAP-L1xx architecture.
LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a.

LCDC on DA8xx consists of two independent controllers, the Raster
Controller and the LCD Interface Display Driver (LIDD) controller.  LIDD
further supports character and graphic displays.

This patch adds support for the graphic display (Sharp LQ035Q3DG01) found
on the DA830 based EVM.  The EVM details can be found at:
http://support.spectrumdigital.com/boards/dskda830/revc/.
