96  * struct sysc - TI sysc interconnect target module registers and capabilities
98  * @module_pa: physical address of the interconnect target module
99  * @module_size: size of the interconnect target module
100  * @module_va: virtual address of the interconnect target module
101  * @offsets: register offsets from module base
102  * @mdata: ti-sysc to hwmod translation data for a module
103  * @clocks: clocks used by the interconnect target module
105  * @nr_clocks: number of clocks used by the interconnect target module
106  * @rsts: resets used by the interconnect target module
108  * @cap: interconnect target module capabilities
109  * @cfg: interconnect target module configuration
112  * @revision: interconnect target module revision
114  * @reserved: target module is reserved and already in use
119  * @idle_work: work structure used to perform delayed idle on a module
120  * @pre_reset_quirk: module specific pre-reset quirk
121  * @post_reset_quirk: module specific post-reset quirk
122  * @reset_done_quirk: module specific reset done quirk
123  * @module_enable_quirk: module specific enable quirk
124  * @module_disable_quirk: module specific disable quirk
125  * @module_unlock_quirk: module specific sysconfig unlock quirk
126  * @module_lock_quirk: module specific sysconfig lock quirk
642  * sysc_parse_and_check_child_range - parses module IO region from ranges
646  * module range. But we do want the offsets for these registers from the
647  * module base. This allows us to check them against the legacy hwmod
802  * sysc_parse_one - parses the interconnect target module registers
862 			dev_err(ddata->dev, "register outside module range");
888  * sysc_ioremap - ioremap register space for the interconnect target module
891  * Note that the interconnect target module registers can be anywhere
892  * within the interconnect target module range. For example, SGX has
893  * them at offset 0x1fc00 in the 32MB module address space. And cpsw
895  * interconnect target module registers are at the beginning of
896  * the module range though.
965  * sysc_show_rev - read and show interconnect target module revision
999  * sysc_show_registers - show information about interconnect target module
1063 	 * the module reset quirk is enabled. Skip status check on enable.
1074 	 * Some subsystem private interconnects, like DSS top level module,
1424 		/* Disable target module if it is enabled */
1430 	/* Enable target module */
1447 	/* Disable target module if no leave_enabled was set */
1545 	/* Quirks that need to be set based on the module address */
1550 	/* Quirks that need to be set based on detected module */
1706  * Early quirks based on module base and register offsets only that are
1707  * needed before the module revision can be read
1802 	/* Remap the whole module range to be able to reset dispc outputs */
1890 /* 1-wire needs module's internal clocks enabled for reset */
2119  * target module.
2137  * Note that the caller must ensure the interconnect target module is enabled
2192  * At this point the module is configured enough to read the revision but
2193  * module may not be completely configured yet to use PM runtime. Enable
2254 	/* No re-enable of clockdomain autoidle to prevent module autoidle */
