David van Moolenbroek	660d34cd85	I2C: change BUSC_I2C_xxx to use own protocol Previously it would use bits of the character driver protocol, which will change heavily. In the new situation, the BUSC_I2C_xxx requests use a protocol more in line with the PCI protocol, with the reply code in m_type.

Thomas Cort	75bd3009d3	libi2cdriver: add functions for IC register access Many i2c device drivers used similar code to access registers on the ICs they drive. This commit implements that functionality in libi2cdriver and updates the drivers to use the library instead of their own register access functions. The net result is 375+ fewer lines of code and less work for people developing new drivers. The two exceptions were cat24c256 and parts of tda19988. They access the bus in uncommon ways. It doesn't make sense at this time to move their read/write functions into libi2cdriver. Change-Id: Id8280b71af33b710a49944d7f20a7262be9f5988	2013-09-18 08:10:26 -04:00

I2C: change BUSC_I2C_xxx to use own protocol

Previously it would use bits of the character driver protocol, which
will change heavily.  In the new situation, the BUSC_I2C_xxx requests
use a protocol more in line with the PCI protocol, with the reply code
in m_type.

libi2cdriver: add functions for IC register access

Many i2c device drivers used similar code to access registers on
the ICs they drive. This commit implements that functionality in
libi2cdriver and updates the drivers to use the library instead of
their own register access functions. The net result is 375+ fewer
lines of code and less work for people developing new drivers.

The two exceptions were cat24c256 and parts of tda19988. They access
the bus in uncommon ways. It doesn't make sense at this time to
move their read/write functions into libi2cdriver.
