mfd: tps65219: Add driver for TI TPS65219 PMIC
The TPS65219 is a power management IC PMIC designed to supply a wide range of SoCs in both portable and stationary applications. Any SoC can control TPS65219 over a standard I2C interface. It contains the following components: - Regulators. - Over Temperature warning and Shut down. - GPIOs - Multi Function Pins (MFP) - power-button This patch adds support for tps65219 PMIC. At this time only the functionalities listed below are made available: - Regulators probe and functionalities - warm and cold reset support - SW shutdown support - Regulator warnings via IRQs - Power-button via IRQ Signed-off-by: Jerome Neanne <jneanne@baylibre.com> Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221104152311.1098603-5-jneanne@baylibre.com
