Subject: [PATCH v5 10/11] ARM: dts: aspeed-g4: Set spi-max-frequency for all flashes
Date: Mon,  2 May 2022 10:13:40 +0200	[thread overview]
Message-ID: <20220502081341.203369-11-clg@kaod.org> (raw)
In-Reply-To: <20220502081341.203369-1-clg@kaod.org>

From: Tao Ren <rentao.bupt@gmail.com>

Set "spi-max-frequency" to 50 MHz for all the flashes under the FMC
controller to ensure the clock frequency is calculated correctly.
