PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
in memory allocation failure after ~1h of uptime (system does not have
115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
allocated.
Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.
This patch attempts to fix those issues.
Patch is based on Russell King's work.

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.

dsi_vc_send_bta_sync() waits for BTA interrupt with a 500ms timeout. If
a DSI error happens, no BTA is received and the timeout triggers. This

the BTA, thus speeding up the fail-path considerably.

Before this patch only clocks that perfectly match were used and if

On OMAP3, the pixel clock for the LCD manager was derived through DISPC_FCLK as:
Lcd Pixel clock = DISPC_FCLK / lcd / pcd
Where lcd and pcd are divisors in the DISPC_DIVISOR register.
On OMAP4, the pixel clocks for LCD1 and LCD2 managers are derived from 2 new
clocks named LCD1_CLK and LCD2_CLK. The pixel clocks are calculated as:
Lcd_o Pixel clock = LCDo_CLK / lcdo /pcdo, o = 1, 2
Where lcdo and pcdo registers are divisors in DISPC_DIVISORo registers.
LCD1_CLK and LCD2_CLK can have DSS_FCLK, and the M4 divider clocks of DSI1 PLL
and DSI2 PLL as clock sources respectively. Introduce functions to select and
get the clock source for these new clocks. Modify DISPC functions get the
correct lck and pck rates based on the clock source of these clocks. Since
OMAP2/3 don't have these clocks, force OMAP2/3 to always have the LCD_CLK source
as DSS_CLK_SRC_FCK by introducing a dss feature.
Introduce clock source names for OMAP4 and some register field changes in
DSS_CTRL on OMAP4.
Currently, LCD2_CLK can only have DSS_FCLK as its clock source as DSI2 PLL
functionality hasn't been introduced yet. BUG for now if DSI2 PLL is selected as
clock.

Using dss_features to select independent core clock divider and setting
it. Added the register used, to DISPC context save and restore group
-----------------------------------------------------------------------
In OMAP4, the minimum DISPC_CORE_CLK required can be expressed as:
DISPC_CORE_CLK >= max(PCLK1*HSCALE1, PCLK2*HSCALE2, ...)
Where PCLKi is the pixel clock generated by MANAGERi and HSCALEi is the
maximum horizontal downscaling done through MANAGERi
Based on the usecase, core clk can be increased or decreased at runtime
to save power. Such mechanism are not yet implemented. Hence, we set the
core clock divisor to 1, to support maximum range of resolutions

The OMAP4 DISPC_DIVISOR1 is backward compatible to OMAP3xxx DISPC_DIVISOR.
However DISPC_DIVISOR is also provided in OMAP4, to control DISPC_CORE_CLK
independent of Primary and Secondary display clocks.
Renamed DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch), to facilitate introduction
of DISPC_DIVISOR register, which is specific for OMAP4. OMAP4 has 3 registers
DISPC_DIVISOR, DISPC_DIVISOR1 and DISPC_DIVISOR2.
Also updated, all the usages of DISPC_DIVISOR(ch) to DISPC_DIVISORo(ch).
Use DISPC_DIVISORo(ch) when DISPC_DIVISOR1 or DISPC_DIVISOR2 has to be

In OMAP3xxx DISPC_DIVISOR register has a logical clock divisor (lcd_div)
field. The lcd_div is common, for deciding the DISPC core functional clock
frequency, and the final pixel clock frequency for LCD display.
In OMAP4, there are 2 LCD channels, hence two divisor registers, DISPC_DIVISOR1
and DISPC_DIVISOR2. Also, there is a third register DISPC_DIVISOR.
The DISPC_DIVISOR in OMAP4 is used to configure lcd_div exclusively for core
functional clock configuration. For pixel clock configuration of primary and
secondary LCDs, lcd_div of DISPC_DIVISOR1 and DISPC_DIVISOR2 are used
respectively

When using OMAP2_DSS_USE_DSI_PLL, which selects DSI PLL as source clock
for DISPC, the DSI needs the vdds_dsi regulator. Latest regulator
changes broke this, causing the the code to not acquire the regulator
when using OMAP2_DSS_USE_DSI_PLL.
This patch acquires the vdds_dsi regulator in dsi_pll_init(), fixing the
issue. This is is just a quick hack to get the OMAP2_DSS_USE_DSI_PLL
option working. There shouldn't be any other downside in this solution
than some extra lines of code.
OMAP2_DSS_USE_DSI_PLL is itself a big hack, and should be removed, and
the feature itself should be implemented in a more sane way. However,
the solution is not trivial, and people are using DSI PLL to get more
exact pixel clocks, so this hack is an acceptable temporary solution for
the time being.
