Subject: [PATCH v6 8/8] arm64: dts: rockchip: Enable SFC for Odroid Go Advance
Date: Tue, 8 Jun 2021 10:33:05 +0800 [thread overview]
Message-ID: <20210608023305.25371-4-jon.lin@rock-chips.com> (raw)
In-Reply-To: <20210608023305.25371-1-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.
