From e31083f9185928ea093c61152c139bb4c96c7ad2 Mon Sep 17 00:00:00 2001 From: Chris Morgan Date: Thu, 12 Aug 2021 21:46:39 +0800 Subject: [PATCH 051/478] arm64: dts: rockchip: Enable SFC for Odroid Go Advance This enables the Rockchip Serial Flash Controller for the Odroid Go Advance. Note that while the attached SPI NOR flash and the controller both support quad read mode, only 2 of the required 4 pins are present. The rx bus width is set to 2 for this reason, and tx bus width is set to 1 for compatibility reasons.
