[PATCH 0/2] firmware: exynos-acpm: allow use during system shutdown

[André Draszik]

One user of this ACPM driver is a PMIC driver that needs to communicate
with the PMIC during late system shutdown and at that time we are not
allowed to sleep anymore.

This series address this by switching the code to using udelay() in the
specific case of system shutdown. This approach was inspired by I2C's
i2c_in_atomic_xfer_mode(), which has to deal with a similar corner
case.
