- * include/linux/platform.h - platform driver definitions
- *
- * Because of the prolific consumerism of the average American,
- * and the dominant marketing budgets of PC OEMs, we have been
- * blessed with frequent updates of the PC architecture. 
- *
- * While most of these calls are singular per architecture, they 
- * require an extra layer of abstraction on the x86 so the right
- * subsystem gets the right call. 
- *
- * Basically, this consolidates the power off and reboot callbacks 
- * into one structure, as well as adding power management hooks.
- *
- * When adding a platform driver, please make sure all callbacks are 
- * filled. There are defaults defined below that do nothing; use those

- * The function is passed some sort of HANDLE from which a cache_detail
- * structure can be determined (via SETUP, DETAIL), a template
- * cache entry (type RTN*), and a "set" flag.  Using the HASHFN and the 
- * TEST, the function will try to find a matching cache entry in the cache.
- * If "set" == 0 :
- *    If an entry is found, it is returned
- *    If no entry is found, a new non-VALID entry is created.
- * If "set" == 1 and INPLACE == 0 :
- *    If no entry is found a new one is inserted with data from "template"
- *    If a non-CACHE_VALID entry is found, it is updated from template using UPDATE
- *    If a CACHE_VALID entry is found, a new entry is swapped in with data
- *       from "template"
- * If set == 1, and INPLACE == 1 :
- *    As above, except that if a CACHE_VALID entry is found, we UPDATE in place
- *       instead of swapping in a new entry.
- *
- * If the passed handle has the CACHE_NEGATIVE flag set, then UPDATE is not
- * run but insteead CACHE_NEGATIVE is set in any new item.
 
- *  In any case, the new entry is returned with a reference count.
- *
- *    
- * RTN is a struct type for a cache entry
- * MEMBER is the member of the cache which is cache_head, which must be first
- * FNAME is the name for the function   
- * ARGS are arguments to function and must contain RTN *item, int set.  May
- *   also contain something to be usedby SETUP or DETAIL to find cache_detail.
- * SETUP  locates the cache detail and makes it available as...
- * DETAIL identifies the cache detail, possibly set up by SETUP
- * HASHFN returns a hash value of the cache entry "item"
- * TEST  tests if "tmp" matches "item"
- * INIT copies key information from "item" to "new"
- * UPDATE copies content information from "item" to "tmp"
- * INPLACE is true if updates can happen inplace rather than allocating a new structure
- *
- * WARNING: any substantial changes to this must be reflected in
- *   net/sunrpc/svcauth.c(auth_domain_lookup)
- *  which is a similar routine that is open-coded.

+ *  RPC client per-operation statistics provide latency and retry
+ *  information about each type of RPC procedure in a given RPC program.
+ *  These statistics are not for detailed problem diagnosis, but simply
+ *  to indicate whether the problem is local or remote.
+ *
+ *  These counters are not meant to be human-readable, but are meant to be
+ *  integrated into system monitoring tools such as "sar" and "iostat".  As
+ *  such, the counters are sampled by the tools over time, and are never
+ *  zeroed after a file system is mounted.  Moving averages can be computed
+ *  by the tools by taking the difference between two instantaneous samples
+ *  and dividing that by the time between the samples.
+ *
+ *  The counters are maintained in a single array per RPC client, indexed
+ *  by procedure number.  There is no need to maintain separate counter
+ *  arrays per-CPU because these counters are always modified behind locks.

+/* msp3400 routing
+   ===============
+
+   The msp3400 has a complicated routing scheme with many possible
+   combinations. The details are all in the datasheets but I will try
+   to give a short description here.
+
+   Inputs
+   ======
+
+   There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+   to select which tuner input to use and which SCART input to use. The
+   selected tuner input, the selected SCART input and all I2S inputs go to
+   the DSP (the tuner input first goes through the demodulator).
+
+   The DSP handles things like volume, bass/treble, balance, and some chips
+   have support for surround sound. It has several outputs: MAIN, AUX, I2S
+   and SCART1/2. Each output can select which DSP input to use. So the MAIN
+   output can select the tuner input while at the same time the SCART1 output
+   uses the I2S input.
+
+   Outputs
+   =======
+
+   Most DSP outputs are also the outputs of the msp3400. However, the SCART
+   outputs of the msp3400 can select which input to use: either the SCART1 or
+   SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+   bypassing the DSP.
+
+   Summary
+   =======
+
+   So to specify a complete routing scheme for the msp3400 you will have to
+   specify in the 'input' field of the v4l2_routing struct:
+
+   1) which tuner input to use
+   2) which SCART input to use
+   3) which DSP input to use for each DSP output
+
+   And in the 'output' field of the v4l2_routing struct you specify:
+
+   1) which SCART input to use for each SCART output
+
+   Depending on how the msp is wired to the other components you can
+   ignore or mute certain inputs or outputs.
+
+   Also, depending on the msp version only a subset of the inputs or
+   outputs may be present. At the end of this header some tables are
+   added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+   1) the tuner (SIF) input
+   2) the SCART input
+   Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+   input, bits 4-7 are reserved.

+   a DSP input.
+
+   The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+   (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+   There also is a quasi-peak detector output, but that is not used by
+   this driver and is set to the same input as the loudspeaker output.
+   Not all outputs are supported by all msp models. Setting the input
+   of an unsupported output will be ignored by the driver.
+
+   There are up to 16 DSP inputs to choose from, so each output is
+   assigned 4 bits.
+
+   Note: the 44x8G can mix two inputs and feed the result back to the
+   DSP. This is currently not implemented. Also not implemented is the
+   multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
