From c376ea9e46215fbfa09b371f79c821fa5a51f26e Mon Sep 17 00:00:00 2001 From: Hu Ziji Date: Thu, 30 Mar 2017 17:22:56 +0200 Subject: [PATCH] mmc: sdhci: Export sdhci_start_signal_voltage_switch() in sdhci.c Export sdhci_start_signal_voltage_switch() from sdhci.c. Thus vendor sdhci driver can implement its own signal voltage switch routine.
