Subject: [PATCH 0/3] media: Support runtime PM and system sleep for
 TI-CSI2RX

This series adds support for runtime power management and system sleep
for the TI (J721E) CSI2RX pipeline.

Some basic testing with suspend-to-idle mode has been performed to
ensure that any ongoing stream resumes smoothly after wakeup. More
testing with suspend-to-memory mode will be done later, as I need to
update the device management boot firmware, which supports newer APIs
used by the mainline kernel.

I have picked PATCH 1/3 from Changhuang's earlier series [1] with minor
modifications.
