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