[PATCH v8 00/34] i.MX Media Driver

[Steve Longerbeam]

In version 8:

- Switched to v4l2_fwnode APIs.

- Always pass a valid CSI id to ipu_set_ic_src_mux() in imx-ic-prp, even
  if the IC is receiving from the VDIC. The reason is due to a bug in the
  i.MX6 reference manual: from experiment it is determined that the CSI id
  select bit in IPU_CONF register selects which CSI is routed to either
  the VDIC or the IC, and is independent of whether the IC is set to
  receive from a CSI or the VDIC. Sugested by Marek Vasut <marex at denx.de>.

- ov5640: propagate error codes from all i2c register accesses.
  Sugested by Sakari Ailus <sakari.ailus at iki.fi>.

- ov5640: drop the entity stream count check in ov5640_s_stream().
  Sugested by Sakari Ailus <sakari.ailus at iki.fi>.

- ov5640: Fix manual exposure control. The manual exposure setting
  (in line periods) cannot exceed the max exposure value in registers
  {0x380E, 0x380F} + {0x350C,0x350D}, however the max eposure value was
  not being calcualted correctly.

- ov5640: the video mode register tables require auto gain/exposure be
  disabled before programming the register set. However auto gain/exp was
  being disabled by direct register write. This caused the auto gain/exp
  control values to be inconsistent with the actual hardware setting. Fixed
  by going through v4l2-ctrl when disabling auto gain/exp.

- ov5640: converted virtual channel macro to a module parameter, default
  to channel 0.

- ov5640: override the v4l2-ctl lock to use the ov5640 subdev driver's
  lock. Sugested by Sakari Ailus <sakari.ailus at iki.fi>.

- ov5640: switch to unit-less V4L2_CID_EXPOSURE. Using
  V4L2_CID_EXPOSURE_ABSOLUTE will require converting from 100-usec units
  to line periods and vice-versa. Sugested by Sakari Ailus and
  Pavel Machek <pavel at ucw.cz>.

- ov5640: drop dangling regulator_bulk_disable() from probe/remove.
  Sugested by Sakari Ailus <sakari.ailus at iki.fi>.

- FIM: move input capture channel selection out of the device-tree and
  make this a V4L2 control. In order to support attaching a FIM to prpencvf,
  the FIM cannot have any device-tree configuration, because prpencvf has
  no device node. The FIM now is completely configurable via its V4L2
  controls.

- FIM: drop imx_media_fim_set_power(), and move the input capture channel
  request to imx_media_fim_set_stream(). This allows to drop csi_s_power()
  as well, since the latter only called imx_media_fim_set_power().

- FIM: add a spinlock to protect the frame_interval_monitor() from the
  setting of new control values. The frame_interval_monitor() is called
  from interrupt context so a spinlock must be used.

- Updated to version 8 video-mux patchset from Philipp Zabel
  <p.zabel at pengutronix.de>.
