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

[Yemike Abhilash Chandra]

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

[PATCH v2 1/4] arm64: dts: ti: j722s-evm: Add DT nodes for power regulators

[Yemike Abhilash Chandra]

Add device tree nodes for two regulators on the J722S-EVM. VSYS_3V3 is the
output of LM5141-Q1, and it serves as an input to TPS22990 which produces
VSYS_3V3_EXP [1]. VSYS_3V3_EXP serves as vin-supply to CSI RPI Connectors.

[PATCH v2 2/4] arm64: dts: ti: j722s-evm: Add MUX to control CSI2RX

[Yemike Abhilash Chandra]

J722S EVM has the CSI2RX routed to a MIPI CSI connector and to 22-pin RPi
camera connector through an analog mux with GPIO control, model that so
that an overlay can control the mux state according to connected cameras.

[PATCH v2 4/4] arm64: dts: ti: k3-j722s-evm: Add overlay for TEVI OV5640

[Yemike Abhilash Chandra]

From: Vaishnav Achath <vaishnav.a@ti.com>

TechNexion TEVI OV5640 camera is a 5MP camera that can be used with
J722S EVM through the 22-pin CSI-RX connector. Add a reference overlay
for quad TEVI OV5640 modules on J722S EVM.

We have kept this alpha sorted so far. Please stick with the

I know this is an aberration.. but anyways.. just one off..
