2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen1-656/+0
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

2013-10-31DMA-API: video: clcd: add dma_set_mask_and_coherent() callRussell King1-0/+5

2011-02-19ARM: clcd: add method for describing display capabilitiesRussell King1-11/+84
The ARM CLCD PL110 controller in TFT mode provides two output formats based on whether the controller is in 24bpp mode or not - either 5551 or 888. PL111 augments this with a 444 and 565 modes. Some implementations provide an external MUX on the PL110 output to reassign the bits to achieve 565 mode. Provide a system of capability flags to allow the CLCD driver to work out what is supported by each panel and board, and therefore which display formats are permitted.

2010-08-18VIDEO: amba clcd: don't disable an already disabled clockRussell King1-2/+8
Fix the clock enable/disable tracking in the AMBA CLCD driver so that the driver doesn't try to disable an already disabled clock, thereby causing the clock (if shared) to become unbalanced. This resolves a problem with CLCD on LPC32xx ARM platforms. Reported-by: Kevin Wells <wellsk40@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-03-14Video: ARM CLCD: Better fix for swapped IENB and CNTL registersRussell King1-7/+24
On PL111, as found on Realview and other platforms, these registers are always arranged as CNTL then IENB. On PL110, these registers are IENB then CNTL, except on Versatile platforms. Re-arrange the handling of these register swaps so that PL111 always gets it right without resorting to ifdefs, leaving the only case needing special handling being PL110 on Versatile. Fill out amba/clcd.h with the PL110/PL111 register definition differences in case someone tries to use the PL110 specific definitions on PL111.

Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up handling of log-levels and newlines") changed printk semantics. printk lines with multiple KERN_<level> prefixes are no longer emitted as before the patch. <level> is now included in the output on each additional use.

2009-06-11[ARM] 5544/1: Trust PrimeCell resource sizesLinus Walleij1-1/+1
I found the PrimeCell/AMBA Bus drivers distrusting the resource passed in as part of the struct amba_device abstraction. This patch removes all hard coded resource sizes found in the PrimeCell drivers and move the responsibility of this definition back to the platform/board device definition, which already exist and appear to be correct for all in-tree users of these drivers. We do this using the resource_size() inline function which was also replicated in the only driver using the resource size, so that has been changed too. The KMI_SIZE was left in kmi.h in case someone likes it. Test-compiled against Versatile and Integrator defconfigs, seems to work but I don't posess these boards and cannot test them.

The second argument of the probe method points to the amba_id structure, so it's better passed with the correct type. None of the current in-tree drivers uses the pointer, so they have only been checked for a clean compile. Change suggested by Russell King.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas1-1/+0
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
