"unknown" lcd_types[] entry is needed for proper operation of
the driver, add it back.

video: fbdev: pxafb: Convert to use match_string() helper

2018-05-15T10:41:10+00:00

The new helper returns index of the matching string in an array.
We are going to use it here.

drivers/video: Convert remaining uses of pr_warning to pr_warn

2017-03-21T15:13:10+00:00

To enable eventual removal of pr_warning

This makes pr_warn use consistent for drivers/video

Prior to this patch, there were 6 uses of pr_warning and
25 uses of pr_warn in drivers/video

video: fbdev: pxafb: add missing of_node_put() in of_get_pxafb_mode_info()

2016-08-30T09:04:16+00:00

This node pointer is returned by of_graph_get_next_endpoint() with
refcount incremented in this function. of_node_put() on it before
exitting this function.

Found by Coccinelle.

video: fbdev: pxafb: potential NULL dereference on error

2016-08-11T14:54:57+00:00

If we "goto out;" then it calls display_timings_release(timings);
Since "timings" is NULL, that's going to oops.  Just return directly.

dma, mm/pat: Rename dma__writecombine() to dma__wc()

2016-03-09T13:57:51+00:00

Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.

Build tested successfully with allmodconfig.

The following Coccinelle SmPL patch was used for this simple
transformation:

@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@

-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)

@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@

-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)

@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@

-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

video: fbdev: pxafb: initial devicetree conversion

2015-12-15T13:41:24+00:00

This patch brings a first support of pxa framebuffer devices to a
devicetree pxa platform, as was before platform data.

There are restrictions with this port, the biggest one being the lack of
support of smart panels. Moreover the conversion doesn't provide a way
to declare multiple framebuffer configurations with different bits per
pixel, only the LCD hardware bus width is used.

The patch was tested on both pxa25x, pxa27x and pxa3xx platform (namely
lubbock, mainstone and zylonite).
