TPS65224 has a similar register map to TPS6594 with a few differences. SPI, I2C, ESM, PFSM, Regulators and GPIO features overlap between the two devices. TPS65224 is a Power Management IC (PMIC) which provides regulators and other features like GPIOs, Watchdog, Error Signal Monitor (ESM) and Pre-configurable Finite State Machine (PFSM). The SoC and the PMIC can communicate through the I2C or SPI interfaces. The PMIC TPS65224 additionally has a 12-bit ADC. Data Sheet for TPS65224: https://www.ti.com/product/TPS65224-Q1 Driver re-use is applied following the advice of the following series: https://lore.kernel.org/lkml/2f467b0a-1d11-4ec7-8ca6-6c4ba66e5887@baylibre.com/ The features implemented in this series are: - TPS65224 Register definitions - Core (MFD I2C and SPI entry points) - PFSM - ESM - Regulators - Pinctrl TPS65224 Register definitions: This patch adds macros for register field definitions of TPS65224 to the existing TPS6594 driver. Core description: I2C and SPI interface protocols are implemented, with and without the bit-integrity error detection feature (CRC mode). PFSM description: Strictly speaking, PFSM is not hardware. It is a piece of code. PMIC integrates a state machine which manages operational modes. Depending on the current operational mode, some voltage domains remain energized while others can be off. PFSM driver can be used to trigger transitions between configured states. ESM description: This device monitors the SoC error output signal at its nERR_MCU input pin. On error detection, ESM driver toggles the PMIC nRSTOUT pin to reset the SoC. Regulators description: 4 BUCKs and 3 LDOs. BUCK12 can be used in dual-phase mode. Pinctrl description: TPS65224 family has 6 GPIOs. Those GPIOs can also serve different functions such as I2C or SPI interface or watchdog disable functions. The driver provides both pinmuxing for the functions and GPIO capability.
