video: fbdev: pxafb: clear allocated memory for video modes

2018-09-26T06:39:25Z

[ Upstream commit b951d80aaf224b1f774e10def672f5e37488e4ee ] When parsing the video modes from DT properties, make sure to zero out memory before using it. This is important because not all fields in the mode struct are explicitly initialized, even though they are used later on.

video: fbdev: pxafb: match_string() conversion fixup

"unknown" lcd_types[] entry is needed for proper operation of the driver, add it back. Fixes: 6d09dfe70f8f ("video: fbdev: pxafb: Convert to use match_string() helper") Reported-by: Andy Shevchenko Cc: Arvind Yadav Signed-off-by: Bartlomiej Zolnierkiewicz

The new helper returns index of the matching string in an array. We are going to use it here. Signed-off-by: Andy Shevchenko Cc: Arvind Yadav Signed-off-by: Bartlomiej Zolnierkiewicz

clk_prepare_enable() can fail here and we must check its return value. Signed-off-by: Arvind Yadav Signed-off-by: Bartlomiej Zolnierkiewicz

drivers/video: Convert remaining uses of pr_warning to pr_warn

2017-03-21T15:13:10Z

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 Signed-off-by: Joe Perches Cc: Benjamin Herrenschmidt Signed-off-by: Bartlomiej Zolnierkiewicz

2016-08-30T09:04:16Z

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. Signed-off-by: Wei Yongjun Acked-by: Robert Jarzmik Signed-off-by: Tomi Valkeinen

video: fbdev: pxafb: potential NULL dereference on error

2016-08-11T14:54:57Z

If we "goto out;" then it calls display_timings_release(timings); Since "timings" is NULL, that's going to oops. Just return directly. Fixes: 420a488278e8 ('video: fbdev: pxafb: initial devicetree conversion') Signed-off-by: Dan Carpenter Acked-by: Robert Jarzmik Signed-off-by: Tomi Valkeinen

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

2016-03-09T13:57:51Z

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

2015-12-15T13:41:24Z

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). Signed-off-by: Robert Jarzmik Signed-off-by: Tomi Valkeinen
