Subject: [PATCH v1 00/14] Add support for TI TPS65219 PMIC.
Date: Tue, 19 Jul 2022 11:17:28 +0200 [thread overview]
Message-ID: <20220719091742.3221-1-jneanne@baylibre.com> (raw)
Not implemented
- DVS
1-Regulators:
Full implementation and test
Visual check: cat /sys/kernel/debug/regulator/regulator_summary
Full validation requires userspace-consumer and virtual-regulator
LDO1 is not used and output can be probbed on TP84.
Changes vs RFC:
Use standard regmap helpers only.
Reshaped integrating review feedbacks.
2-Reset WARM/COLD
test procedure: launch reboot on the console and check visually
warm vs. cold can be configured on the kernel command-line at boot time.
Default is cold, but adding `reboot=w`
to kernel command allow testing warm reboot.
Alternative:
`# echo warm > /sys/kernel/reboot/mode`
Changes vs RFC:
Hooked to standard linux/reboot.h
Add pr_flush to ensure output to console happens.
3-SW Shutdown
test procedure: launch halt on the console and check visually
Note: enters in competition with other source during probe
Board Test Points can be used to check voltage after system shutdown.
baseport is not handling wakeup.
A power OFF/ON cycle is needed to recover.
Changes vs RFC:
Standard system-power-controller has been implemented to enable override.
4-Interrupt Pin (nINT): NEW, was not implemented in RFC
Interrupt occurring on PMIC TPS65219 is propagated to SOC
through EXTINTn pin connected to gic500 interrupt controller
Interrupt lines for TPS65219 shows-up on console:
cat /proc/interrupts
Validation:
Create a Residual Voltage interrupt and handling and interrupt source is cleared.
`tps65219 0-0030: Registered residual voltage for LDO1`
`533: 1 0 tps65219_irq 35 Edge LDO1_RV`
Mapped to power button (use TP90 to GND to emulate a physical button)
5-PB Startup and Shutdown: NEW, was not implemented in RFC
New implementation to support both rising and falling edge.
TPS65219 has different interrupts compared to other TPS6521* chips.
TPS65219 defines two interrupts for the powerbutton one for push and one
for release.
Interrupt support: cat proc/interrupts
`557: 0 0 tps65219_irq 47 Edge tps65219-pwrbutton.1.auto`
`558: 0 0 tps65219_irq 48 Edge tps65219-pwrbutton.1.auto`
