23 | : Standard Linux driver framework for creating
24 | : exposing and managing interfaces to the rest
25 | : of the kernel or userland. Also uses _fw.c to load
26 | : firmware direct into the PCIe bus, bypassing layers.
27 V
28 saa7164_api..() : Translate kernel specific functions/features
29 | : into command buffers.
30 V
31 saa7164_cmd..() : Manages the flow of command packets on/off,
32 | : the bus. Deal with bus errors, timeouts etc.
33 V
34 saa7164_bus..() : Manage a read/write memory ring buffer in the
35 | : PCIe Address space.
36 |
37 | saa7164_fw...() : Load any frimware
38 | | : direct into the device
