From b21561463885d4c2f40a133dae1ff00ef3f0175f Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu <siva.durga.paladugu@xilinx.com> Date: Tue, 12 Jan 2016 15:12:16 +0530 Subject: [PATCH] mmc: zynq_sdhci: Added qurik to disable high speed Add quirk to disable high speed incase the high speed was broken.This solves the issue where the the controller is used in High Speed Mode and the the hold time requirement for the JEDEC/MMC 4.41 specification is NOT met. This timing issue is not on all boards and hence provided config option to enable it when required.
