Subject: ARM: OMAP: voltage: voltage layer present, even when CONFIG_PM=n
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2edc7ba5e8fdba327e16d3d0086e831c5fe6f577;p=mv-sheeva.git

ARM: OMAP: voltage: voltage layer present, even when CONFIG_PM=n

Even when CONFIG_PM=n, we try to scale the boot voltage to a sane,
known value using OPP table to find matching voltage based on boot
frequency.  This should be done, even when CONFIG_PM=n to avoid
mis-configured bootloaders and/or boot voltage assumptions made by
boot loaders.

Also fixes various compile problems due to depenencies between voltage
domain and powerdomain code (also present when CONFIG_PM=n).
