Subject: [PATCH v3 11/11] ARM: dts: aspeed-g4: Set spi-max-frequency for all flashes
Date: Fri,  4 Mar 2022 09:36:43 +0100	[thread overview]
Message-ID: <20220304083643.1079142-12-clg@kaod.org> (raw)
In-Reply-To: <20220304083643.1079142-1-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.
