Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

struct psil_ep {
	u32 thread_id;
	struct psil_endpoint_config ep_config;
};

/**
 * struct psil_ep_map - PSI-L thread ID configuration maps
 * @name:	Name of the map, set it to the name of the SoC
 * @src:	Array of source PSI-L thread configurations
 * @src_count:	Number of entries in the src array
 * @dst:	Array of destination PSI-L thread configurations
 * @dst_count:	Number of entries in the dst array
 *
 * In case of symmetric configuration for a matching src/dst thread (for example
 * 0x4400 and 0xc400) only the src configuration can be present. If no dst
 * configuration found the code will look for (dst_thread_id & ~0x8000) to find
 * the symmetric match.
