regulator: drivers: Add TI TPS65219 PMIC regulators support
The regulators set consists of 3 bucks DCDCs and 4 LDOs. The output voltages are configurable and are meant to supply power to the main processor and other components. Validation: Visual check: cat /sys/kernel/debug/regulator/regulator_summary Validation: userspace-consumer and virtual-regulator required to test further Enable/Disable: cat /sys/devices/platform/userspace-consumer-VDDSHV_SD_IO_PMIC/state echo disabled > /sys/devices/platform/ userspace-consumer-VDDSHV_SD_IO_PMIC/state echo enabled > /sys/devices/platform/ userspace-consumer-VDDSHV_SD_IO_PMIC/state Change voltage: cat /sys/devices/platform/regulator-virtual-ldo1/min_microvolts echo 1000000 > /sys/devices/platform/regulator-virtual-ldo1/ min_microvolts echo 3000000 > /sys/devices/platform/regulator-virtual-ldo1/ max_microvolts Signed-off-by: Jerome Neanne <jneanne@baylibre.com> Link: https://lore.kernel.org/r/20220805121852.21254-9-jneanne@baylibre.com Signed-off-by: Mark Brown <broonie@kernel.org>
