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.
