Add support for TI TPS65219 PMIC.
Merge series from Jerome Neanne <jneanne@baylibre.com>: This driver supports - 3 Buck regulators and 4 LDOs - low-power standby mode - warm/soft reset - basic fault handling (via interrupts). - power button 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.

Optional property that sets the EN/PB/VSENSE pin to be a

|
||||
TPS65219 has a multipurpose pin called EN/PB/VSENSE that can be either
|
||||
1. EN in which case it functions as an enable pin.
|
||||
2. VSENSE which compares the voltages and triggers an automatic
|
||||
on/off request.
|
||||
3. PB in which case it can be configured to trigger an interrupt
|
||||
to the SoC.
|
||||
ti,power-button reflects the last one of those options
|
||||
where the board has a button wired to the pin and triggers
|
||||
an interrupt on pressing it.
