[PATCH v5 03/12] mmc: sdhci: Export sdhci_start_signal_voltage_switch() in sdhci.c
From: Gregory CLEMENT <hidden>
Date: 2017-01-11 17:23:56
Also in:
linux-arm-kernel, linux-clk, linux-mmc, lkml
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, the rest · Maintainers:
Ulf Hansson, Adrian Hunter, Linus Torvalds
From: Hu Ziji <huziji@marvell.com> Export sdhci_start_signal_voltage_switch() from sdhci.c. Thus vendor sdhci driver can implement its own signal voltage switch routine.
