2020-02-24media: media/platform: rename VFL_TYPE_GRABBER to _VIDEOHans Verkuil1-1/+1
'GRABBER' is a weird name, all other types map to the /dev device names. Rename to 'VIDEO' to be consistent with the other types. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2019-08-07media: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-3/+1
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-03-29media: replace strncpy() by strscpy()Mauro Carvalho Chehab1-2/+2
The strncpy() function is being deprecated upstream. Replace it by the safer strscpy(). While here, replace a few occurences of strlcpy() that were recently added to also use strscpy().

2019-02-18media: imx-pxp: Start using the format VUYA32 instead of YUV32 (v2)Vivek Kasireddy1-4/+10
Buffers generated with YUV32 format seems to be incorrect, hence use VUYA32 instead. Changes from v1: Add both formats VUYA32 and VUYX32 but associate only VUYX32 to the output queue as the alpha channel of buffers is ignored on this queue.

2018-09-11media: imx-pxp: add i.MX Pixel Pipeline driverPhilipp Zabel1-0/+1752
Add a V4L2 mem-to-mem scaler/CSC driver for the Pixel Pipeline (PXP) version found on i.MX6ULL SoCs. A similar variant is used on i.MX7D. Since this driver only uses the legacy pipeline, it should be reasonably easy to extend it to work with the older PXP versions found on i.MX6UL, i.MX6SX, i.MX6SL, i.MX28, and i.MX23. The driver supports scaling and colorspace conversion. There is currently no support for rotation, alpha-blending, and the LUTs.
