- * @_sysc_cache: internal-use hwmod flags
- * @_mpu_rt_va: cached register target start address (internal use)
- * @_mpu_port: cached MPU register target slave (internal use)
- * @opt_clks_cnt: number of @opt_clks
- * @master_cnt: number of @master entries
- * @slaves_cnt: number of @slave entries
- * @response_lat: device OCP response latency (in interface clock cycles)
- * @_int_flags: internal-use hwmod flags
- * @_state: internal-use hwmod state
- * @_postsetup_state: internal-use state to leave the hwmod in after _setup()
- * @flags: hwmod flags (documented below)
- * @_lock: spinlock serializing operations on this hwmod
- * @node: list node for hwmod list (internal use)
- *
- * @main_clk refers to this module's "main clock," which for our
- * purposes is defined as "the functional clock needed for register
- * accesses to complete."  Modules may not have a main clock if the

- *
- * Parameter names beginning with an underscore are managed internally by
