Subject: [PATCH V3 02/10] ARM: OMAP3+: SmartReflex: class drivers should use struct omap_sr *
From: Jean Pihet <j-pihet@...com>
Convert SmartReflex "class" functions to take a struct omap_sr *, rather than
a struct voltagedomain *. SmartReflex code should be driver code and not
tightly coupled to OMAP subarchitecture-specific structures.
Based on Paul's original code for the SmartReflex driver conversion.
