Hello,
The latest PM branch, is now available in the linux-omap tree. The
git-shortlog is below[1], but from a high level, this branch includes
support for
- full-chip retention in dynamic idle
- full-chip retention in suspend
- full-chip OFF in dynamic idle
- full-chip OFF in suspend
The choice of retention versus off-mode can be selected using
/sys/power/enable_off_mode (zero by default.)
Tested on 3430SDP.
To test:
# echo 1 > /sys/power/clocks_off_while_idle
# echo 1 > /sys/power/sleep_while_idle
# echo 1 > /sys/power/voltage_off_while_idle
and optionally for off-mode
# echo 1 > /sys/power/enable_off_mode
