Subject: [PATCH v2 0/4] Add overlays for IMX219 and OV5640 on J722S

This series adds IMX219 and OV5640 overlays to enable support
for 4 sensors on J722S. This provides a reference for a user to
enable a different sensor on any of the ports.

Changelog:
Changes in v2:
- J722S EVM has the CSI2RX routed to MIPI CSI connector and to 22-pin RPi
  camera connector through an analog mux. Initially, the analog mux was modeled
  in the overlay in v1, But following the convention used on other platforms,
  the analog mux has been moved to the base device tree. So that an overlay
  can control the mux state according to connected cameras.
- Correct the vin-supply for RPI camera connectors. To do the same add missing
  power regulators in the device tree.
- Mark GPIO used in the comment
- Add reset-gpios property for tevi-OV5640 overlay
