This is a next version of series of patches(based on Eduardo Valentin's patch set) adding a basic support for system control module, on OMAP4+ context. It is a working in progress. Main changes since previous patch set version: - Bandgap and usb phy: drivers are now independent from control module driver, they use their own functions to acess scm registers. - omap-control-core: resources aren't hardcoded, they are specified in dts file. - omap-control-core: Control module is a built-in driver - added control module select to ARCH_HAS_CONTROL_MODULE and ARCH_OMAP4. Probably, no configuration option is required! - omap-control-core: Added early init call that ioremaps control module IOMEM window, this allows access of SCM registers very early, for example from omap_type() - omap-control-core: Removed device pointer from omap-control-core API arguments, becuase there can be only one instance control module device. - omap-control-core: removed omap_control_get, omap_control_readl, omap_control_writel - omap-control-core: added omap_control_status_read that is used early in omap_type - Bandgap and usb phy: Added private spinlocks for bandgap and usb drivers. - Bandgap: Check the type of bandgap dynamically in bandgap driver probe function by reading omap core control module revision register CONTROL_GEN_CORE_REVISION. - Bandgap and usb phy: Parent SCM platform device IOMEM resources is used to get the base address of SCM window. - Bandgap masks defines were moved to drivers/thermal/omap-bandgap.c. TODO list for bandgap driver: - Reserve omap-control-core IOMEM window. - Improve thermal zone definition for OMAP4 - Introduce the thermal zones for OMAP5
