From d37b4f37ea40243ad3a126a152920339189afb52 Mon Sep 17 00:00:00 2001 From: Chin-Ting Kuo Date: Fri, 19 Aug 2022 17:01:07 +0800 Subject: [PATCH] arm: dts: aspeed: Update SPI flash node settings For both AST2500 and AST2600, there are three SPI controllers, FMC(Firmware Memory Controller), SPI1 and SPI2. The clock source is HCLK. Following is the basic information for ASPEED SPI controller.
