From 16f4d36c7b8b6aeb0374485acb91afee795ccfc9 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Tue, 11 Jan 2022 07:21:06 -0600 Subject: [PATCH] arm: dts: rz-g2-beacon-u-boot: Enable pinmux for QSPI When booting from QSPI, the boot ROM appears to mux the QSPI pins, but it's not guaranteed to be setup when booting from eMMC. Fix this by explicitly configuring the pinmux.
