Subject: [PATCH 1/3] MMC: rtsx: remove driving adjustment
Date: Mon, 4 Feb 2013 15:45:57 +0800 [thread overview]
Message-ID: <1359963959-2305-2-git-send-email-rogerable@realtek.com> (raw)
In-Reply-To: <1359963959-2305-1-git-send-email-rogerable@realtek.com>
Several new models of readers use different way to select driving
capability(a necessary adjustment along with voltage change). Removing this
from device-independent rtsx_pci_sdmmc module. It will be implemented in
device-depend calls encapsulated by rtsx_pci_switch_output_voltage().
