-Subject: [PATCH] i2c-gpio: Also set bus numbers from reg property
-
-I2C busses can be assigned specific bus numbers using aliases in
-Device Tree - string properties where the name is the alias and the
-value is the path to the node. The current DT parameter mechanism
-does not allow property names to be derived from a parameter value
-in any way, so it isn't possible to generate unique or matching
-aliases for nodes from an overlay that can generate multiple
-instances, e.g. i2c-gpio.
-
-Work around this limitation (at least temporarily) by allowing
-the i2c adapter number to be initialised from the "reg" property
-if present.
