Now that all the driver patches are Acked-by the respective driver
Maintainers. Here is the set of Device Tree patches which were
dependent on the driver patches.
These are boot tested on am437x-sk-evm, am437x-gp-evm, am335x-bone,
am335x-boneblack.
Keerthy (1):
ARM: dts: AM437X-GP-EVM: AM437X-SK-EVM: Make dcdc3 dcdc5 and dcdc6
enable during suspend
Tero Kristo (2):
ARM: dts: am437x-gp-evm: disable DDR regulator in rtc-only/poweroff
mode
ARM: dts: am437x-sk-evm: disable DDR regulator in rtc-only/poweroff
mode

dcdc3, dcdc5, dcdc6 supply ddr and rtc respectively. These
are required to be on during suspend. Hence set the state accordingly.

Without this, the memory will remain active during poweroff consuming
extra power. Please note revision 2.1 PMIC seems to fail when DCDC3
disable is attempted, so this is not done on that PMIC revision. The
PMIC revision checks in the regulator patches make sure of this.
