From d53cc1c37e5a4006fb23df8e54dc4a50e01732d9 Mon Sep 17 00:00:00 2001 From: Rui Miguel Silva Date: Tue, 19 Jul 2016 15:41:30 +0100 Subject: [PATCH] greybus: sdio: add switch voltage operation Core sd/mmc needs the start_signal_voltage_switch operation to be defined to issue a voltage switch command. So, we define it here even though we do not need to take in action on it, since all voltage control is done in the Module.
