[PATCH v2 1/5] dt-bindings: at24: consistently document the compatible property

[Bartosz Golaszewski]

Current description of the compatible property for at24 is quite vague.

Specify an exact list of accepted compatibles and document the - now
deprecated - strings which were previously used in device tree files.

 Required properties:
 
-  - compatible : should be "<manufacturer>,<type>", like these:
-
-	"atmel,24c00", "atmel,24c01", "atmel,24c02", "atmel,24c04",
-	"atmel,24c08", "atmel,24c16", "atmel,24c32", "atmel,24c64",

-
-	"renesas,r1ex24002"
-
-	The following manufacturers values have been deprecated:
-	"at", "at24"
-
-	 If there is no specific driver for <manufacturer>, a generic
-	 device with <type> and manufacturer "atmel" should be used.
-	 Possible types are:
-	 "24c00", "24c01", "24c02", "24c04", "24c08", "24c16", "24c32", "24c64",
-	 "24c128", "24c256", "24c512", "24c1024", "spd"
