[PATCH v3 0/2] regulator: rpi-panel-v2: Add vcc-supply

[Shashank Maurya]

This series adds a vcc-supply property to both the dt-binding and the
driver:

- Patch 1/2: dt-bindings - documents the vcc-supply property as an
    optional property.
  - Patch 2/2: driver - uses devm_regulator_get() to obtain and enable
    the vcc supply at the start of probe, before any I2C access.

---
Changes in v3:
- dt-bindings: make vcc-supply optional instead of required, to preserve
  compatibility with existing device trees that do not describe the
  supply.
- Driver is unchanged from v2: devm_regulator_get() returns a dummy
  regulator when the supply is absent, so an optional binding needs no
  driver change.
- Link to v2: https://patch.msgid.link/20260907-rpi_reg-v2-0-0c59aa60d31f@oss.qualcomm.com

Changes in v2:
  - Made vcc-supply required instead of optional (devm_regulator_get()
    instead of devm_regulator_get_optional()).
  - Added vcc-supply to the required list in the dt-binding schema.

Changes in v1:
  - Initial submission with optional vcc-supply support.
