13 | : Standard Linux driver framework for creating
14 | : exposing and managing interfaces to the rest
15 | : of the kernel or userland. Also uses _fw.c to load
16 | : firmware direct into the PCIe bus, bypassing layers.
17 V
18 saa7164_api..() : Translate kernel specific functions/features
19 | : into command buffers.
20 V
21 saa7164_cmd..() : Manages the flow of command packets on/off,
22 | : the bus. Deal with bus errors, timeouts etc.
23 V
24 saa7164_bus..() : Manage a read/write memory ring buffer in the
25 | : PCIe Address space.
26 |
27 | saa7164_fw...() : Load any frimware
28 | | : direct into the device
