Hi all,

This patch series adds initial support for the Renesas RAA215300 PMIC
(CONFIG_REGULATOR_RAA215300 kernel symbol) on the RZ/G3E SMARC EVK board.
To enable PMIC communication, the I2C2 pinctrl configuration is added first,
followed by the RAA215300 node.

Patch 1 adds the pin control configuration for I2C2 to enable communication
with the PMIC over the appropriate bus.

Patch 2 introduces the device tree node for the RAA215300 PMIC, connected via
I2C2. This will indirectly enable support for the built-in RTC chip, compatible
with the ISL1208 (CONFIG_RTC_DRV_ISL1208 symbol needs to be enabled for support)

RTC and its alarm (via wakealarm sysfs file) have been tested and validated on
RZ/G3E SMARC EVK board.

This patch series depends upon [1].
Feedback is welcome.
