[PATCH 0/3] ARM: dts: Enable suspend configuration

[Keerthy]

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

[PATCH 1/3] ARM: dts: AM437X-GP-EVM: AM437X-SK-EVM: Make dcdc3 dcdc5 and dcdc6 enable during suspend

[Keerthy]

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

[PATCH 2/3] ARM: dts: am437x-gp-evm: disable DDR regulator in rtc-only/poweroff mode

[Keerthy]

From: Tero Kristo <t-kristo@ti.com>

Without this, the memory will remain active during poweroff consuming
extra power.

[PATCH 3/3] ARM: dts: am437x-sk-evm: disable DDR regulator in rtc-only/poweroff mode

[Keerthy]

From: Tero Kristo <t-kristo@ti.com>

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.
