Hi, I'd like to recommend this commit for stable v3.18 onwards: commit c61f30a255550bbfc6b83c1ca720661489cac4c0 Author: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Date: Fri Dec 18 11:51:36 2015 +0100 ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz This change corrects an long-standing miss-match between the clock speed specified in the kernel (DTS) and what is actually present in the hardware. My understanding is that this can result in unexpected behaviour. I believe Geert can provide more details if needed.
