[PATCH v2 00/18] CSI2RX support on J721E

[Pratyush Yadav]

Hi,

This series adds support for CSI2 capture on J721E. It includes some
fixes to the Cadence CSI2RX driver, adds Rx support to Cadence DPHY
driver, and finally adds the TI CSI2RX wrapper driver.

Tested on TI's J721E with OV5640 sensor.

Changes in v2:
- Use phy_pm_runtime_get_sync() and phy_pm_runtime_put() before making
  calls to set PHY mode, etc. to make sure it is ready.
- Add all 64 threads, instead of having only the one thread being
  currently used by the driver.
- Use dmaengine_get_dma_device() instead of directly accessing
  dma->device->dev.
- Do not set dst_addr_width when configuring slave DMA.
- Move to a separate subdir and rename to j721e-csi2rx.c
- Convert compatible to ti,j721e-csi2rx.
- Move to use Media Controller centric APIs.
- Improve cleanup in probe when one of the steps fails.
- Add colorspace to formats database.
- Set hw_revision on media_device.
- Move video device initialization to probe time instead of register time.
- Rename to ti,j721e-csi2rx.yaml
- Add an entry in MAINTAINERS.
- Add a description for the binding.
- Change compatible to ti,j721e-csi2rx to make it SoC specific.
- Remove description from dmas, reg, power-domains.
- Remove a limit of 2 from #address-cells and #size-cells.
- Fix add ^ to csi-bridge subnode regex.
- Make ranges mandatory.
- Add unit address in example.
- Add a reference to cdns,csi2rx in csi-bridge subnode.
- Expand the example to include the csi-bridge subnode as well.
- Re-order subject prefixes.
- Drop reg description.
- Add a description for each DPHY clock.
- Rename dphy@... to phy@... in example.
- Add Laurent's R-by.
- Re-order subject prefixes.
- Re-order subject prefixes.
- Add power-domain to the example.
- Add Laurent's R-by.
- Re-order subject prefixes.
- Convert OV5640 to use runtime PM and drop Cadence CSI2RX s_power patch.
- Drop subdev call wrappers from cdns-csi2rx.
- Move VPE and CAL to a separate subdir.
- Rename ti-csi2rx.c to j721e-csi2rx.c
