From: Rajendra Nayak <rnayak@xxxxxx>
This patch updates the sleep and wake sequences and updates the
device group associations:
Sleep sequence:
-1-Turn off HFCLKOUT
-2-Turn off Vdd1
-3-Turn off Vdd2
-4-Turn off VPLL1
Wakeup p3 sequence
-1-Turn on HFCLKOUT
Wakeup P12 sequence
-1-Turn on HFCLKOUT
-2-Turn on Vdd1
-3-Turn on Vdd2
-4-Turn on VPLL1
Also HFCLKOUT is associated to device group P3. This makes
sure sys clk from PMIC to OMAP is cut during RET as well as OFF.
VDD1 and VDD2 are associated to device group P1 so that they
are cut only during OFF.
CLKEN by default is assigned to all device groups and is left
unchanged. This makes sure the oscillator is not shutdown
in RET states.
