From e142173e8dc5ddd923761581bcc877a786f3c2ff Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Sat, 18 Nov 2017 21:07:45 +0100 Subject: 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.
