OK no need to update patch 5 then.

OK. Please use your updated patch 1 as it contains the oops in
the description. Kevin, are you OK with that?
So that leaves me only the second one to queue that adds checks
for the PMIC info for boards that don't have it, see below.

Subject: [PATCH] ARM: OMAP2+: PM: only register TWL with voltage layer when
device is present
Current code registers voltage layer details for TWL PMIC even when a TWL
has not been registered. Fix this to only register the TWL with voltage
layer when the TWL PMIC is initialized by board-level code.
