media: imx-mipi-csis: Check csis_fmt validity before use

2023-02-26T10:21:33+00:00

The find_csis_format() may return NULL in case supported format is not found, check the return value of find_csis_format() before using the result to avoid NULL pointer dereference.

media: imx-pxp: convert to regmap

2023-02-08T08:21:30+00:00

Replace the readl and writel with regmap to ease debugging the registers from userspace. Suggested-by: Alexander Stein Signed-off-by: Michael Tretter Reviewed-by: Philipp Zabel Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: imx-pxp: Use non-threaded IRQ

2023-02-08T08:21:14+00:00

There's no need to use threaded IRQs with the PXP, as the interrupt handler doesn't need to sleep and doesn't perform any time-consuming operation. Switch to regular IRQ handler. This fixes lockups of the PXP noticed on i.MX7, where the PXP would stop generating interrupts after a variable number of frames (from a few dozens to a few hundreds). The root cause is however unknown. Signed-off-by: Laurent Pinchart Signed-off-by: Michael Tretter Reviewed-by: Philipp Zabel Signed-off-by: Mauro Carvalho Chehab

media: imx-pxp: Introduce pxp_read() and pxp_write() wrappers

2023-02-08T08:20:52+00:00

Add pxp_read() and pxp_write() functions to wrap readl() and writel() respectively. This can be useful for debugging register accesses. Signed-off-by: Laurent Pinchart Signed-off-by: Michael Tretter Reviewed-by: Philipp Zabel Signed-off-by: Mauro Carvalho Chehab

media: imx-pxp: Pass pixel format value to find_format()

2023-02-08T08:19:56+00:00

The find_format() function looks up format information for a given pixel format. It takes a v4l2_format pointer, but only uses the contained pixel format value. To prepare it for being used by callers that don't have v4l2_format, modify it to take the pixel format value directly.

media: imx-pxp: Add media controller support

2023-02-08T08:19:31+00:00

Register a media device for the PXP, using the v4l2-mem2mem MC infrastructure to populate the media graph. No media device operation is implemented, the main use of the MC API is to allow consistent discovery of media devices for userspace.

media: imx-pxp: Don't set bus_info manually in .querycap()

2023-02-08T08:19:08+00:00

The v4l2_capability.bus_info field is set by the V4L2 core when left empty by the .querycap() handler. This is the recommended practice, in order to ensure bus_info coherence between drivers. Don't set it manually. Signed-off-by: Laurent Pinchart Signed-off-by: Michael Tretter Reviewed-by: Philipp Zabel Signed-off-by: Mauro Carvalho Chehab
