int omap4_cminst_wait_module_idle	(	u8	part,
		u16	inst,
		s16	cdoffs,
		u16	clkctrl_offs
	)

omap4_cminst_wait_module_idle - wait for a module to be in 'disabled' state : PRCM partition ID that the CM_CLKCTRL register exists in : CM instance register offset (*_INST macro) : Clockdomain register offset (*_CDOFFS macro) : Module clock control register offset (*_CLKCTRL macro)

Wait for the module IDLEST to be disabled. Some PRCM transition, like reset assertion or parent clock de-activation must wait the module to be fully disabled.

int omap4_cminst_wait_module_ready	(	u8	part,
		u16	inst,
		s16	cdoffs,
		u16	clkctrl_offs
	)

omap4_cminst_wait_module_ready - wait for a module to be in 'func' state : PRCM partition ID that the CM_CLKCTRL register exists in : CM instance register offset (*_INST macro) : Clockdomain register offset (*_CDOFFS macro) : Module clock control register offset (*_CLKCTRL macro)

Wait for the module IDLEST to be functional. If the idle state is in any the non functional state (trans, idle or disabled), module and thus the sysconfig cannot be accessed and will probably lead to an "imprecise external abort"
