i2c-sibyte: SWARM I2C board initialization
The standard rtc-m41t80.c driver cannot be used with the SWARM as it is, because the board does not provide setup information for the I2C core. As a result the bus and the address to probe for the M41T80 chip is not known. Here is a set of changes that fix the problem: 1. swarm-i2c.c -- SWARM I2C board setup, currently for the M41T80 chip on the bus #1 only (there is a MAX6654 temperature sensor on the bus #0 which may be added in the future if we have a driver for that chip). 2. The i2c-sibyte.c BCM1250A SMBus controller driver now registers its buses as numbered so that board setup is correctly applied. Signed-off-by: Maciej W.
