35 * 0x0 func: Module is fully functional, including OCP
36 * 0x1 trans: Module is performing transition: wakeup, or sleep, or sleep
38 * 0x2 idle: Module is in Idle mode (only OCP part). It is functional if
40 * 0x3 disabled: Module is disabled and cannot be accessed
50 /* Read a register in a CM instance */

87 * _clkctrl_idlest - read a CM_*_CLKCTRL register; mask & shift IDLEST bitfield
88 * @inst: CM instance register offset (*_INST macro)

107 * Returns true if the module's CM_*_CLKCTRL.IDLEST bitfield is either
121 * _clktrctrl_write - write @c to a CM_CLKSTCTRL.CLKTRCTRL register bitfield
123 * @inst: CM instance register offset (*_INST macro)
126 * @c must be the unshifted value for CLKTRCTRL - i.e., this function

161 * am33xx_cm_clkdm_enable_hwsup - put a clockdomain in hwsup-idle mode
162 * @inst: CM instance register offset (*_INST macro)
166 * hardware-supervised idle mode. No return value.
