/*
- Changes:
- 24.08.2002
- Fixed the typo in sis630_access (Thanks to Mark M. Hoffman)
- Changed sis630_transaction.(Thanks to Mark M. Hoffman)
- 18.09.2002
- Added SIS730 as supported.
- 21.09.2002
- Added high_clock module option.If this option is set
- used Host Master Clock 56KHz (default 14KHz).For now we save old Host
- Master Clock and after transaction completed restore (otherwise
- it's confuse BIOS and hung Machine).
- 24.09.2002
- Fixed typo in sis630_access
- Fixed logical error by restoring of Host Master Clock
- 31.07.2003
- Added block data read/write support.

Status: beta
Supports:
SIS 630
SIS 730
+ SIS 964
+
+ Notable differences between chips:
+ +------------------------+--------------------+-------------------+
+ | | SIS630/730 | SIS964 |
+ +------------------------+--------------------+-------------------+
+ | Clock | 14kHz/56kHz | 55.56kHz/27.78kHz |
+ | SMBus registers offset | 0x80 | 0xE0 |
+ | SMB_CNT | Bit 1 = Slave Busy | Bit 1 = Bus probe |
+ | (not used yet) | Bit 3 is reserved | Bit 3 = Last byte |
+ | SMB_PCOUNT | Offset + 0x06 | Offset + 0x14 |
+ | SMB_COUNT | 4:0 bits | 5:0 bits |
+ +------------------------+--------------------+-------------------+
+ (Other differences don't affect the functions provided by the driver)
Note: we assume there can only be one device, with one SMBus interface.
