[RFC PATCH 0/7] aspeed: i2c: Add new mode support

[Joe Komlodi]

Hi all,

This series migrates the Aspeed I2C controller to use the register API,
and then adds new mode support.

New mode has some behavior changes and a register layout change compared
to old mode.

The series starts by adding "shared field" macros to help simplify logic
when adding new mode.
Generally, the macros are to be used in cases where register locations
change depending on what mode a peripheral is operating in, but
the fields in those registers have the same offsets.
Specifically, this happens very frequently with new and old I2C modes on
Aspeed I2C.

After that we migrate over to the register API and then add new mode
support.

Thanks!
Joe
