From 6e36024ad688bfa13289c137799aecc4bbfc9604 Mon Sep 17 00:00:00 2001 From: Jakob Unterwurzacher Date: Mon, 18 Feb 2019 09:25:36 +0100 Subject: rk3399-puma.dts: reduce eMMC freq to 100MHz Running at the default frequency of 200MHz, CRC errors (error -84 = EILSEQ) have been observed on three boards. Reduce the freqency to 100MHz to fix the issue on the affected boards and for safety on all others.
