This patch set applies on top of pm-1 branch. This has context save/restore support implemented for the following modules GPMC, UART, GPIO, I2C, PRCM, INTC, SCM, SRAM. A sysfs knob to dynamically control OFF mode is provided at /sys/power/enable_off_mode. This is set to 0 (disabled) by default. After bootup execute the following commands to be able to achieve OFF mode in idle as well as in suspend. # echo -n 1 > /sys/power/enable_off_mode # echo -n 1 > /sys/power/clocks_off_while_idle # echo -n 1 > /sys/power/sleep_while_idle regards, Rajendra
