From 0718e59ae259f7c48155b4e852d8b0632d59028e Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 25 Apr 2014 12:57:18 +0100 Subject: mmc: sdhci: move FSL ESDHC reset handling quirk into esdhc code The Freescale esdhc driver is the only driver which needs the interrupt registers restored after a reset. Move this quirk to be part of the ESDHC driver implementation.
