omap_hwmod_pad_route_irq - route an I/O pad wakeup to a particular MPU IRQ : struct omap_hwmod * containing hwmod mux entries : array index in oh->mux of the hwmod mux entry to route wakeup : the hwmod mpu_irqs array index of the IRQ to trigger on wakeup
When an I/O pad wakeup arrives for the dynamic or wakeup hwmod mux entry number for the hwmod , trigger the interrupt service routine for the hwmod's mpu_irqs array index . If this function is not called for a given pad_idx, then the ISR associated with 's first MPU IRQ will be triggered when an I/O pad wakeup occurs on that pad. Note that is the index of the dynamic or wakeup entry: if there are other entries not marked with OMAP_DEVICE_PAD_WAKEUP or OMAP_DEVICE_PAD_REMUX, these entries are NOT COUNTED in the dynamic pad index. This function must be called separately for each pad that requires its interrupt to be re-routed this way. Returns -EINVAL if there is an argument problem or if does not have hwmod mux entries or MPU IRQs; returns -ENOMEM if memory cannot be allocated; or 0 upon success.
XXX This function interface is fragile. Rather than using array indexes, which are subject to unpredictable change, it should be using hwmod IRQ names, and some other stable key for the hwmod mux pad records.

Sets the hwmod state that will enter at the end of setup() (called by omap_hwmod_setup*()). See also the documentation for _setup_postsetup(), above. Returns 0 upon success or -EINVAL if there is a problem with the arguments or if the hwmod is in the wrong state.

omap_hwmod_set_slave_idlemode - set the hwmod's OCP slave idlemode : struct omap_hwmod * : SIDLEMODE field bits (shifted to bit 0)
Sets the IP block's OCP slave idlemode in hardware, and updates our local copy. Intended to be used by drivers that have some erratum that requires direct manipulation of the SIDLEMODE bits. Returns -EINVAL if is null, or passes along the return value from _set_slave_idlemode().
XXX Does this function have any current users? If not, we should remove it; it is better to let the rest of the hwmod code handle this. Any users of this function should be scrutinized carefully.

omap_hwmod_setup_one - set up a single hwmod : const char * name of the already-registered hwmod to set up
Initialize and set up a single hwmod. Intended to be used for a small number of early devices, such as the timer IP blocks used for the scheduler clock. Must be called after omap2_clk_init(). Resolves the struct clk names to struct clk pointers for each registered omap_hwmod. Also calls _setup() on each hwmod. Returns -EINVAL upon error or 0 upon success.

omap_hwmod_shutdown - shutdown an omap_hwmod : struct omap_hwmod *
Shutdown an omap_hwmod . Intended to be called by omap_device_shutdown(). Returns -EINVAL on error or passes along the return value from _shutdown().

omap_hwmod_softreset - reset a module via SYSCONFIG.SOFTRESET bit : struct omap_hwmod *
This is a public function exposed to drivers. Some drivers may need to do some settings before and after resetting the device. Those drivers after doing the necessary settings could use this function to start a reset by setting the SYSCONFIG.SOFTRESET bit.
