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.
Logs from running the above commands, => pmic list | Name | Parent name | Parent uclass @ seq | pmic@48 | i2c@4900000 | i2c @ 0 | status: 0 | watchdog@12 | i2c@20000000 | i2c @ 1 | status: 0 => reg list | Device | regulator-name | Parent | buck12 | buck12 | pmic@48 | buck3 | buck3 | pmic@48 | buck4 | buck4 | pmic@48 | ldo1 | ldo1 | pmic@48 | ldo2 | ldo2 | pmic@48 | ldo3 | ldo3 | pmic@48 => regulator dev buck12 dev: buck12 @ buck12 => 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
