From 73eeac49be566d389df728b5335f7146d03d2f90 Mon Sep 17 00:00:00 2001 From: Shiji Yang Date: Mon, 8 Jul 2024 00:05:14 +0800 Subject: [PATCH] ramips: limit max spi clock frequency to 50 MHz In the past few years, we have received several reports about SPI Flash not working properly. This is caused by excessively fast clock frequency. It's really annoying to fix them one by one. Let's reduce these aggressive frequencies to 50 MHz. This is a safe and suggested value in the vendor SDK.
