[RFC PATCH v2 00/11] OMAP System Control Module

[Konstantin Baydarov]

  Hello.

  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 API functions.
Dependency was removed from Kconfig.
- omap-control-core: driver is basically the same as arch/arm/mach-omap2/control.c, but 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
omap-control-core.c API to be called 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.
- 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.

TODO list for bandgap driver:
- Currently, bandgap and usb phy are children of control module, but, in fact, the drivers are independent,
so probably they should be independent entries in dts as well.
- Reserve omap-control-core IOMEM window.
- Improve thermal zone definition for OMAP4
- Introduce the thermal zones for OMAP5

Overall series has been tested only with panda board OMAP4430, so bandgap and usb phy drivers weren't tested at all.
