2011-05-24video: mb862xxfb: relocate register space to get contiguous vramAnatolij Gustschin
By default the GDC registers are located in the middle of the 64MiB area for video RAM and registers. When 32MiB VRAM or more is used, relocate the register space to the top of the 64MiB space so that we get the contiguous VRAM for GDC frame buffer layers, drawing frames, capture and cursor buffers.

2011-05-24video: mb862xxfb: use pre-initialized configuration for PCI GDCsAnatolij Gustschin
If the bootloader has already initialized the display controller, do not re-initialize it in the driver. Take over the bootloader's configuration instead. This is already supported for non PCI GDCs Lime and Mint. Add this functionality for PCI GDCs Coral-P and Coral-PA. It is useful to avoid flicker and also avoids unneeded init delays while booting.

2011-05-24video: mb862xxfb: correct fix.smem_len field initializationAnatolij Gustschin
Initialize smem_len field to the actual frame buffer size and not to the whole video RAM size. This prevents overwriting other video memory (which could be used by other layers, cursors or accelerated drivers) by frame buffer applications relying on fix.smem_len.

2011-05-24video: s3c-fb: correct transparency checking in 32bppJingoo Han
32bpp means ARGB 8888 in the driver, therfore the transparency length and offset should be 8 and 24 respectively. However, the transparency length and offset were previously 0, which means that the driver supports RGB 888 without alpha blending when 32bpp is used. So, the transparency checking in 32bpp is corrected so that the transparency length and offset are 8 and 24 respectively.

It might make sense to built it as both (though that is not currently possible) but it certainly doesn't make sense to build it as neither!

2011-05-23OMAP: DSS2: Add support for NV12 formatAmber Jain
Add the support for NV12 color format. Configure base address for UV component of NV12 color format. Change the way chroma scaling is handled for YUV formats on OMAP4 by enabling chroma-resampling for video pipeline and hence using FIR2 register set for scaling UV. Changes to _dispc_set_scaling(), because of the reason above, are: - call _dispc_set_scaling_common() to handle scaling for all color formats except for OMAP4 where it only handles scaling for RGB or Y-component - call _dispc_set_scaling_uv() for special handling required for UV component on OMAP4. - dispc_set_scaling_uv() also resets chroma-resampling bit for RGB color modes. Contains chroma scaling (_dispc_set_scaling_uv) design and implemented by Lajos Molnar <molnar@ti.com> Signed-off-by: Amber Jain <amber@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-05-23OMAP: DSS2: Add new registers for NV12 supportAmber Jain
Add new registers specific to UV color component that are introduced in OMAP4. Add simple helper functions to configure the newly added registers. These new registers are mainly: - UV base address registers used specifically for NV12 color-format - FIR registers used for UV-color-component scaling on OMAP4 - Accumulator registers used for UV-color-component scaling Add these new registers to save/restore and DUMPREG functions. Also add two new features for OMAP4: - FEAT_HANDLE_UV_SEPARATE - this is used on OMAP4 as UV color-component requires separate handling. - FEAT_ATTR2 - this is used on OMAP4 to configure new ATTRIBUTES2 register.

2011-05-23OMAP: DSS2: Ensure non-zero FIR values are configuredAmber Jain
FIR values can never be zero as per TRM, and the current code writes zero when scaling is not used. It was not causing any problem as scaling was disabled when zero was written. Its still safer to not write zero to it in any case. Now we configure correct FIR values even when scaling is not used (i.e. set FIR to 1024 when scaling is not used), but the scaling enable bits are still kept off if the scaling is not needed.

Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.
