ARM: OMAP AM33xx: clockdomains: Add clockdomain data and respective operations
AM33XX PRCM module consists of various clockdomains, in all total we have 18 clockdomains available, with following controlling options, - SW Sleep: sw forced sleep transition - SW Wakeup: sw forced wakeup transition This patch adds all available clockdomain data, respective clockdomain operations for AM33XX family of device, and also integrates it into existing OMAP framework.
