From 95069704cdd88c1e0494081056df08b9526b9ae1 Mon Sep 17 00:00:00 2001 From: Tim Harvey Date: Wed, 8 Apr 2015 12:54:56 -0700 Subject: [PATCH] imx: ventana: add DT fixup for GW54xx compatibility with older kernels Certain older kernels in use by some customers erroneously define a uart3 for GW54xx with a pinmux that conflicts with NAND. This will remove that node to avoid such conflicts.
