Subject: [RFC PATCH v9 10/10] arm64: dts: rockchip: Enable SFC for Odroid Go Advance
Date: Fri, 25 Jun 2021 16:41:25 +0800	[thread overview]
Message-ID: <20210625084125.13685-1-jon.lin@rock-chips.com> (raw)
In-Reply-To: <20210625084036.13464-1-jon.lin@rock-chips.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.
