-Subject: [PATCH] mips: ralink: introduce commonly used remap node function
-
-The ralink_of_remap() function is repeated several times on SoC specific
-source files. They have the same structure, but just differ in compatible
-strings. In order to make commonly use of these codes, this patch
-introduces a newly designed mtmips_of_remap_node() function to match and
-remap all supported system controller and memory controller nodes.
-
-Build and run tested on MT7620 and MT7628.
