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.

* DESCRIPTION:
* Part of DRX driver.
* Data access protocol: Fast Access Sequential Interface (fasi)
* Fast access, because of short addressing format (16 instead of 32 bits addr)
* Sequential, because of I2C.
*
* USAGE:
* Include.

* NOTES:

/********************************************

/*
* Comments about short/long addressing format:
*
* The DAP FASI offers long address format (4 bytes) and short address format
* (2 bytes). The DAP can operate in 3 modes:
* (1) only short
* (2) only long
* (3) both long and short but short preferred and long only when necessary
*
* These modes must be selected compile time via compile switches.
* Compile switch settings for the different modes:
* (1) DRXDAPFASI_LONG_ADDR_ALLOWED=0, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
* (2) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=0
* (3) DRXDAPFASI_LONG_ADDR_ALLOWED=1, DRXDAPFASI_SHORT_ADDR_ALLOWED=1
*
* The default setting will be (3) both long and short.
* The default setting will need no compile switches.
* The default setting must be overridden if compile switches are already
* defined.
