Cover letter [PATCH v4 0/4] OMAP System Control Module

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. As Bandgap and usb phy drivers are now independent from control module driver and they will be sent separately. IIUC, Bandgap driver has already been sent.

OMAP system control module driver provides only one API function - read of CONTROL_STATUS register:
u32 omap_control_status_read(void) that is used in omap_type()

The physical address of CONTROL_STATUS register is specified in DT:

ctrl_module_core: ctrl_module_core at 4A0022C4 {
	compatible = "ti,omap4-control";
	#address-cells = <1>;
	#size-cells = <1>;
	/* ranges; */
	ti,hwmods = "ctrl_module_core";
	reg = <0x4A0022C4 0x4>; /* CONTROL_STATUS register */
};
