* media: mt9m111: set initial frame size other than 0x0Akinobu Mita2019-01-251-0/+2
| | | | | | | | | | | | | | This driver sets initial frame width and height to 0x0, which is invalid. So set it to selection rectangle bounds instead. This is detected by v4l2-compliance detected.

| | | | | | | | | | | | | | This driver doesn't set all members of mbus format field when the VIDIOC_SUBDEV_{S,G}_FMT ioctls are called. This is detected by v4l2-compliance.

| | | | | | | | | | | | | The VIDIOC_SUBDEV_G_FMT ioctl for this driver doesn't recognize V4L2_SUBDEV_FORMAT_TRY and always works as if V4L2_SUBDEV_FORMAT_ACTIVE is specified.

* media: mt9m111: allow to setup pixclk polarityEnrico Scholz2018-12-051-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | The chip can be configured to output data transitions on the rising or falling edge of PIXCLK (Datasheet R58:1[9]), default is on the falling edge. Parsing the fw-node is made in a subfunction to bundle all (future) dt-parsing / fw-parsing stuff. [m.grzeschik@pengutronix.de: Fix inverting clock. INV_PIX_CLOCK bit is set per default. Set bit to 0 (enable mask bit without value) to enable falling edge sampling.] [m.felsch@pengutronix.de: use fwnode helpers] [m.felsch@pengutronix.de: mv fw parsing into own function] [m.felsch@pengutronix.de: adapt commit msg] [sakari.ailus@linux.intel.com: V4L2 API usage changes to compile on media tree master] Signed-off-by: Enrico Scholz <enrico.scholz@sigma-chemnitz.de> Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
* media: mt9m111: add support to select formats and fps for {Q,SXGA}Michael Grzeschik2018-12-051-0/+165
| | | | | | | | | | | | This patch implements the framerate selection using the skipping and readout power-modi features. The power-modi cut the framerate by half and each context has an independent selection bit. The same applies to the 2x skipping feature.

* media: mt9m111: add streaming check to set_fmtMichael Grzeschik2018-12-051-0/+3
| | | | | | | | | | | | | | Currently set_fmt don't care about the streaming status, so the format can be changed during streaming. This can lead into wrong behaviours. Check if the device is already streaming and return -EBUSY to avoid wrong behaviours.

* media: v4l: Remove support for crop default target in subdev driversSakari Ailus2018-10-031-1/+0
| | | | | | | | | | | | | The V4L2 sub-device API does not support the crop default target. A number of drivers apparently still did support this, likely as it was needed by the SoC camera framework. Drop support for the default crop rectaingle in sub-device drivers, and use the bounds rectangle in SoC camera instead.

| | | | | | | | | | | | | | The v4l2_subdev_ops structure is only passed as the third argument of v4l2_i2c_subdev_init, which is const, so the v4l2_subdev_ops structure can be const as well. The other structures are only stored in the v4l2_subdev_ops structure, all the fields of which are const, so these structures can also be const. Done with the help of Coccinelle.
