The ROHM BD96801 "Scalable PMIC" is an automotive grade PMIC which can
scale to different applications by allowing chaining of PMICs. The PMIC
also supports various protection features which can be configured either
to fire IRQs - or to shut down power outputs when failure is detected.
The driver implements basic voltage control and sending error
notifications.
NOTE:
The driver does not support doing configuration which require the PMIC
to be in STBY state. The omitted feature set includes setting safety
limit values, changing LDO voltages and controlling enable state for
some regulators.
Also, the ERRB IRQ is not handled.

Set off-on-delay-us to 500000 us for pp3300_mipibrdg to make sure it
complies with the panel's unprepare delay (the time to power down
completely) of the power sequence. Explicit configuration on the
regulator node is required because mt8192-asurada uses the same power
supply for the panel and the anx7625 DP bridge.
For example, the power sequence could be violated in this sequence:
1. Bridge on: panel goes off, but regulator doesn't turn off (refcount=1).
2. Bridge off: regulator turns off (refcount=0).
3. Bridge resume -> regulator turns on but the bridge driver doesn't
check the delay.
Or in this sequence:
1. Bridge on: panel goes off. The regulator doesn't turn off (refcount=1),
but the .unprepared_time in panel_edp is still updated.
2. Bridge off, regulator goes off (refcount=0).
3. Panel on, but the panel driver uses the wrong .unprepared_time to check
the unprepare delay.

The "output-enable" property is set on uart1's RTS pin. This is bogus
because the hardware does not actually have a controllable output
buffer. Secondly, the implementation incorrectly treats this property
as a request to switch the pin to GPIO output. This does not fit the
intended semantic of "output-enable" and it does not have any affect
either because the pin is muxed to the UART function, not the GPIO
function.
