From d77fe9219af17dce2d00147d904267d4489ae841 Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Sat, 18 Nov 2017 21:07:45 +0100 Subject: [PATCH] ramips: backport MT7628 pinmux fixes According to the datasheet the REFCLK pin is shared with GPIO#37 and the PERST pin is shared with GPIO#36. While at it fix a typo inside the pinmux setup code. The function is called refclk and not reclk. Update device tree source files accordingly.
