Hello,
This patchset adds support for atomic transfers which are required for
shutting down machine properly. Secondly, a (not)suspending I2C is fixed
by this small series as well.
Changelog:
v1: The "i2c: tegra: Support atomic transfers" previously was sent out as
a separate patch, but later I spotted that suspend/resume doesn't
work properly. The "i2c: tegra: Fix suspending in active runtime PM
state" patch depends on the atomic patch because there is a need to
active IRQ-safe mode for the runtime PM by both patches.
I fixed a missed doc-comment of the newly added "is_curr_atomic_xfer"
structure field and added additional comment that explains why IRQ needs
to be disabled for the atomic transfer in the "Support atomic transfers"
patch.
Lastly, I added a minor "i2c: tegra: Rename .." patch that helps to
follow driver's code.
