24  * - add pinmuxing
25  * - init_conn_id_bit (CONNID_BIT_VECTOR)
26  * - implement default hwmod SMS/SDRC flags?
27  * - move Linux-specific data ("non-ROM data") out
89  * struct omap_hwmod_mux_info - hwmod specific mux configuration
105  * struct omap_hwmod_irq_info - MPU IRQs used by the hwmod
107  * @irq: IRQ channel ID (should be non-negative except -1 = terminator)
119  * struct omap_hwmod_dma_info - DMA channels used by the hwmod
121  * @dma_req: DMA request ID (should be non-negative except -1 = terminator)

304  * struct omap_hwmod_class_sysconfig - hwmod class OCP_SYS* data
314  * modules have separate clockdomains for the interface clock and main

501  * @_postsetup_state: internal-use state to leave the hwmod in after _setup()
506  * @main_clk refers to this module's "main clock," which for our
507  * purposes is defined as "the functional clock needed for register
