-Device tree configuration for the I2C busses on the AST24XX, AST25XX, and AST26XX SoCs.

-Required Properties:
-- #address-cells	: should be 1
-- #size-cells		: should be 0
-- reg			: address offset and range of bus
-- compatible		: should be "aspeed,ast2400-i2c-bus"
-			  or "aspeed,ast2500-i2c-bus"
-			  or "aspeed,ast2600-i2c-bus"
-- clocks		: root clock of bus, should reference the APB
-			  clock in the second cell
-- resets		: phandle to reset controller with the reset number in
-			  the second cell
-- interrupts		: interrupt number
-
-Optional Properties:
-- bus-frequency	: frequency of the bus clock in Hz defaults to 100 kHz when not
-		  specified
-- multi-master	: states that there is another master active on this bus.
