11 | * Driver for Siemens reference design card "Easy321-R1". | |
12 | * | |
13 | * This card contains a FALC54 E1/T1 framer and a MUNICH32X 32-channel HDLC | |
14 | * controller. | |
15 | * | |
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. | |
