From d5717e894497124fd44289a37f818ee301640c70 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 2 Apr 2015 10:19:12 +0300 Subject: [PATCH] board: AXS10x - update SDIO clock value With the most recent board firmware correct SDIO clock is 50MHz as opposed to 25 MHz before. Also set max frequency of MMC data exchange equal to SDIO clock - because there's no way to transfer data faster than interface clock.
