[PATCH 0/2] i2c: Aspeed: Add AST2600 compatible string

[Eddie James]

Update the Aspeed I2C driver with the AST2600 compatible string. The default
driver behavior works fine with the AST2600. A new compatible string is needed
to avoid the AST2400 and AST2500 behavior.

[PATCH 1/2] i2c: Aspeed: Add AST2600 compatible

[Eddie James]

The driver default behavior works with the AST2600. We need a new
compatible though to make sure the driver doesn't enable AST2400 or
AST2500 behavior.

Perhaps s/buses/busses/ while you're here.
