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.

Paul Kocialkowski (1):
  phy: Distinguish between Rx and Tx for MIPI D-PHY with submodes

Pratyush Yadav (15):
  phy: cdns-dphy: Prepare for Rx support
  phy: cdns-dphy: Allow setting mode
  phy: cdns-dphy: Add Rx support
  media: cadence: csi2rx: Add external DPHY support
  media: cadence: csi2rx: Soft reset the streams before starting capture
  media: cadence: csi2rx: Set the STOP bit when stopping a stream
  media: cadence: csi2rx: Fix stream data configuration
  media: cadence: csi2rx: Turn subdev power on before starting stream
  media: cadence: csi2rx: Add wrappers for subdev calls
  dmaengine: ti: k3-psil-j721e: Add entry for CSI2RX
  dt-bindings: media: Add DT bindings for TI CSI2RX driver
  media: ti-vpe: csi2rx: Add CSI2RX support
  dt-bindings: phy: Convert Cadence DPHY binding to YAML
  dt-bindings: phy: cdns,dphy: make clocks optional
  dt-bindings: phy: cdns,dphy: add power-domains property

Without patch 1, patch 5 and later won't build. Without patch 11, patch 
13 will not work.

Cover letter is a good place to mention this! And what do you mean by
not working, do we have compile time dependencies? I agree that for
everything to work all the pieces need to land

Splitting the series per subsystem will facilitate merging, but for the
first versions, keeping all patches together facilitate review. I'd
prefer if we could have a v2 that still includes everything, until we
agree on the interface between the two subsystems. At that point, we can
split the series if needed.
