33 * 0x2 idle: Module is in Idle mode (only OCP part). It is functional if
57 /* Read-modify-write a register in CM */
82 * _clkctrl_idlest - read a CM_*_CLKCTRL register; mask & shift IDLEST bitfield
98 * _is_module_ready - can module registers be accessed without causing an abort?
116 * _clktrctrl_write - write @c to a CM_CLKSTCTRL.CLKTRCTRL register bitfield
121 * @c must be the unshifted value for CLKTRCTRL - i.e., this function
137 * am33xx_cm_is_clkdm_in_hwsup - is a clockdomain in hwsup idle mode?
142 * is in hardware-supervised idle mode, or 0 otherwise.
156 * am33xx_cm_clkdm_enable_hwsup - put a clockdomain in hwsup-idle mode
161 * hardware-supervised idle mode. No return value.
169 * am33xx_cm_clkdm_disable_hwsup - put a clockdomain in swsup-idle mode
174 * software-supervised idle mode, i.e., controlled manually by the
175 * Linux OMAP clockdomain code. No return value.
183 * am33xx_cm_clkdm_force_sleep - try to put a clockdomain into idle
187 * Put a clockdomain referred to by (@inst, @cdoffs) into idle
188 * No return value.
196 * am33xx_cm_clkdm_force_wakeup - try to take a clockdomain out of idle
200 * Take a clockdomain referred to by (@inst, @cdoffs) out of idle,
201 * waking it up. No return value.
213 * am33xx_cm_wait_module_ready - wait for a module to be in 'func' state
219 * Wait for the module IDLEST to be functional. If the idle state is in any
220 * the non functional state (trans, idle or disabled), module and thus the

256 return (i < MAX_MODULE_READY_TIME) ? 0 : -EBUSY; in am33xx_cm_wait_module_idle()
260 * am33xx_cm_module_enable - Enable the modulemode inside CLKCTRL
266 * No return value.
280 * am33xx_cm_module_disable - Disable the module inside CLKCTRL
285 * No return value.
