[PATCH v2 0/2] TPS65224 PMIC Driver

[Bhargav Raviprakash]

TPS65224 is a Power Management IC which provides regulators and others
features like GPIOs, RTC, watchdog, ADC, ESMs (Error Signal Monitor),
and PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC
can communicate through the I2C.

Add support for TPS65224 PMIC in U-boot. This includes driver for
PMIC and regulator.

The driver was tested on Ti's custom AM62A EVM using U-boot's
pmic list, regulator list, regulator enable, regulator disable and
regulator value commands. Regulator output voltages were verified.

 => regulator enable
 => regulator value 1500000
 => regulator disable

Changes since v1:
 - corrected coyright lines changed to 2023 in all files
 - Added #define macros for some of the magic numbers, constants
   and offsets to improve readability
