Subject: [RFC PATCH 0/5] Add TI TPS65219 PMIC support for AM642 SK board.
Date: Mon, 13 Jun 2022 11:05:59 +0200 [thread overview]
Message-ID: <20220613090604.9975-1-jneanne@baylibre.com> (raw)
1-Regulators: full implementation
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
Voltage changes monitored on LDO1 output on TP84 for k3-am642-sk board
2-Low power Mode (STBY)
A regulator set_mode with a standby mode is implemented (not tested)
3-Reset WARM/COLD
implemented not tested
4-SD Card VSEL_SD
Implemented, appears in summary as: tps65219-LDO1-SEL-SD GPIO control
not tested
5-Interrupt Pin (nINT)
Not implemented
6-SW Shutdown
Implemented not tested
Note: enters in competition with other source during probe
7-PB Startup and Shutdown
Can be derived from 65217/8 implementation but postponed,
interrupt support required first.
