30 * omap4_cm_wait_module_ready - wait for a module to be in 'func' state
31 * @clkctrl_reg: CLKCTRL module address
32 *
33 * Wait for the module IDLEST to be functional. If the idle state is in any
34 * the non functional state (trans, idle or disabled), module and thus the
35 * sysconfig cannot be accessed and will probably lead to an "imprecise
36 * external abort"
37 *
38 * Module idle state:
39 * 0x0 func: Module is fully functional, including OCP
40 * 0x1 trans: Module is performing transition: wakeup, or sleep, or sleep
41 * abortion
42 * 0x2 idle: Module is in Idle mode (only OCP part). It is functional if
43 * using separate functional clock
44 * 0x3 disabled: Module is disabled and cannot be accessed
