media: platform: place NXP drivers on a separate dir

2022-03-14T08:42:59+00:00

In order to cleanup the main platform media directory, move NXP drivers to their own directory. Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: mx2_emmaprp: Make use of the helper function devm_platform_ioremap_resource()

2021-09-30T08:07:50+00:00

Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mx2_emmaprp: Fix memleak in emmaprp_probe

2020-09-26T08:15:39+00:00

When platform_get_irq() fails, we should release vfd and unregister pcdev->v4l2_dev just like the subsequent error paths.

media: media/platform: rename VFL_TYPE_GRABBER to _VIDEO

2020-02-24T15:54:14+00:00

'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 Signed-off-by: Mauro Carvalho Chehab

media: don't do a 31 bit shift on a signed int

2019-08-26T17:11:10+00:00

On 32-bits archs, a signed integer has 31 bits plus on extra bit for signal. Due to that, touching the 32th bit with something like: int bar = 1 << 31; has an undefined behavior in C on 32 bit architectures, as it touches the signal bit. This is warned by cppcheck. Instead, force the numbers to be unsigned, in order to solve this issue. Signed-off-by: Mauro Carvalho Chehab

media: mx2_emmaprp: use struct v4l2_fh

2019-07-23T15:51:35+00:00

Convert this driver to use struct v4l2_fh and as a result switch to using vb2/v4l2_mem2mem helper functions as well. Only compile-tested due to lack of hardware. This driver is however very similar to the m2m-deinterlace driver in this respect, and that v4l2_fh conversion has been properly tested.

media: mx2_emmaprp: set device_caps in struct video_device

2019-07-22T18:50:00+00:00

Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: media/platform: don't set description in ENUM_FMT

2019-07-22T18:43:59+00:00

The V4L2 core sets the format description and flags for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed. And in am437x-vpfe.c drop an unnecessary f->type assignment in vpfe_enum_fmt().

media: replace strncpy() by strscpy()

2019-03-29T14:26:13+00:00

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(). Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
