+ * struct sdw_intel_link_res - Soundwire Intel link resource structure,
+ * typically populated by the controller driver.
+ * @mmio_base: mmio base of SoundWire registers
+ * @registers: Link IO registers base
+ * @shim: Audio shim pointer
+ * @alh: ALH (Audio Link Hub) pointer
+ * @irq: Interrupt line
+ * @ops: Shim callback ops
+ * @dev: device implementing hw_params and free callbacks
+ * @shim_lock: mutex to handle access to shared SHIM registers
+ * @shim_mask: global pointer to check SHIM register initialization
+ * @clock_stop_quirks: mask defining requested behavior on pm_suspend
+ * @link_mask: global mask needed for power-up/down sequences
+ * @cdns: Cadence master descriptor
+ * @list: used to walk-through all masters exposed by the same controller
