|
|
|
|
+* This file implements functions that correspond to the prism2/hfa384x
|
|
|
|
+* 802.11 MAC hardware and firmware host interface.
|
|
|
|
+*
|
|
|
|
+* The functions can be considered to represent several levels of
|
|
|
|
+* abstraction. The lowest level functions are simply C-callable wrappers
|
|
|
|
+* around the register accesses. The next higher level represents C-callable
|
|
|
|
+* prism2 API functions that match the Intersil documentation as closely
|
|
|
|
+* as is reasonable. The next higher layer implements common sequences
|
|
|
|
+* of invokations of the API layer (e.g. write to bap, followed by cmd).
|
|
|
|
+*
|
|
|
|
+* Common sequences:
|
|
|
|
+* hfa384x_drvr_xxx Highest level abstractions provided by the
|
|
|
|
+* hfa384x code. They are driver defined wrappers
|
|
|
|
+* for common sequences. These functions generally
|
|
|
|
+* use the services of the lower levels.
|
|
|
|
+*
|
|
|
|
+* hfa384x_drvr_xxxconfig An example of the drvr level abstraction. These
|
|
|
|
+* functions are wrappers for the RID get/set
|
|
|
|
+* sequence. They call copy_[to|from]_bap() and
|
|
|
|
+* cmd_access(). These functions operate on the
|
|
|
|
+* RIDs and buffers without validation. The caller
|
|
|
|
+* is responsible for that.
|
|
|
|
+*
|
|
|
|
+* API wrapper functions:
|
|
|
|
+* hfa384x_cmd_xxx functions that provide access to the f/w commands.
|
|
|
|
+* The function arguments correspond to each command
|
|
|
|
+* argument, even command arguments that get packed
|
|
|
|
+* into single registers. These functions _just_
|
|
|
|
+* issue the command by setting the cmd/parm regs
|
|
|
|
+* & reading the status/resp regs. Additional
|
|
|
|
+* activities required to fully use a command
|
|
|
|
+* (read/write from/to bap, get/set int status etc.)
|
|
|
|
+* are implemented separately. Think of these as
|
|
|
|
+* C-callable prism2 commands.
|
|
|
|
+*
|
|
|
|
+* Lowest Layer Functions:
|
|
|
|
+* hfa384x_docmd_xxx These functions implement the sequence required
|
|
|
|
+* to issue any prism2 command. Primarily used by the
|
|
|
|
+* hfa384x_cmd_xxx functions.
|
|
|
|
+*
|
|
|
|
+* hfa384x_bap_xxx BAP read/write access functions.
|
|
|
|
+* Note: we usually use BAP0 for non-interrupt context
|
|
|
|
+* and BAP1 for interrupt context.
|
|
|
|
+*
|
|
|
|
+* hfa384x_dl_xxx download related functions.
|
|
|
|
+*
|
|
|
|
+* Driver State Issues:
|
|
|
|
+* Note that there are two pairs of functions that manage the
|
|
|
|
+* 'initialized' and 'running' states of the hw/MAC combo. The four
|
|
|
|
+* functions are create(), destroy(), start(), and stop(). create()
|
|
|
|
+* sets up the data structures required to support the hfa384x_*
|
|
|
|
+* functions and destroy() cleans them up. The start() function gets
|
|
|
|
+* the actual hardware running and enables the interrupts. The stop()
|
|
|
|
+* function shuts the hardware down. The sequence should be:
|
|
|
|
+* create()
|
|
|
|
+* start()
|
|
|
|
+* .
|
|
|
|
+* . Do interesting things w/ the hardware
|
|
|
|
+* .
|
|
|
|
+* stop()
|
|
|
|
+* destroy()
|
|
|
|
+*
|
|
|
|
+* Note that destroy() can be called without calling stop() first.
