Hi,

This series adds support for Rx mode on Cadence DPHY driver. It has been
split off from [0] to facilitate easier merging. I have still kept it as
v3 to maintain continuity with the previous patches. This series also
includes conversion to YAML binding.

Tested on TI's J721E with OV5640 sensor.

Changes in v3:
- Use a table to select the band.
- Use a table to poll the data lane ready bits.
- Multiply the DPHY HS clock rate by 2 to get the bit rate since the
clock is DDR.
- Add Rob's R-by.

Changes in v2:
- 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.
