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