The compatible string "simple-bus" is well defined in ePAPR, while I see no documentation for the "arm,amba-bus" arnywhere in ePAPR or Documentation/devicetree/. DT is also used by other projects than Linux kernel. It is not a good idea to rely on such an unofficial binding. This commit - replaces "arm,amba-bus" with "simple-bus" - drops "arm,amba-bus" where it is used along with "simple-bus" Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Olof Johansson <olof@lixom.net>
