16 * The driver supports E1 mode with up to 31 channels. We send CRC4 but don't
17 * check it coming in.
18 *
19 * The FALC54 and MUNICH32X have far too many registers and weird modes for
20 * comfort, so I have not bothered typing it all into a "fooreg.h" file,
21 * you will (badly!) need the documentation anyway if you want to mess with
22 * this gadget.
