What happened to this series? I want to add shutdown support to my
platform and I need to write a register on the PMIC in one driver to
configure it for shutdown instead of restart and then write an MMIO
register to tell the PMIC to actually do the shutdown in another driver.
It seems that the notifier solves this case for me, albeit with the
slight complication that I need to order the two with some priority.
Can you use the .shutdown driver callback instead ?
I see other drivers use that, and check for system_state == SYSTEM_POWER_OFF
to power off the hardware.
Yes I think that will work. I'll still have to hook pm_power_off() for
the mmio register, but I guess that's ok and I don't need to worry about
this series then.
