From 62226b68631b5767814224f70f1afc253474d999 Mon Sep 17 00:00:00 2001 From: Jaehoon Chung Date: Fri, 30 Dec 2016 15:30:18 +0900 Subject: [PATCH] mmc: sdhci: move the callback function into sdhci_ops callback function should be moved into sdhci_ops struct. Other controller can use these ops for controlling clock or their own specific register.
