Subject: [PATCH v2 4/4] arm64: dts: rockchip: Enable SFC for Odroid Go Advance
Date: Fri, 28 May 2021 12:00:20 -0500 [thread overview]
Message-ID: <20210528170020.26219-5-macroalpha82@gmail.com> (raw)
In-Reply-To: <20210528170020.26219-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
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 and tx bus width is set to 2 for this reason.
