MFD: TWL6030: Configure MOD & CON processor group to OFF.
For PMIC to enter deeper power state, all the processor group needs
be to turned off and it can be achieved either through HW & SW. In case
of HW, by de-asserting PREQ1/2a/2b/2c/3 pins all the processor group
will be turned off. In case of SW, by configuring DEV_ON register, we can
selectively disable individual processor group.
In most of HW design, only PREQ1 is used to turn Application processor
and PREQ2a/2b/2c/3 are not connected. So to achieve low power state,
MOD & CON processor group needs to disabled through SW.
SW bits gets reset after PMIC exit low power state, so it is necessary
to ensure that during every suspend, SW bits are configured accordingly.
