From: Ulf Hansson <ulf.hansson@xxxxxxxxxx> UHS cards in mode SDR12|25 operates at 1.8V I/O voltage. This patchset adds support to handle the corresponding voltage switch from the default 2.7-3.6 I/O voltage to 1.8V. The first patch, "Fixup regulator handling for vqmmc" has recently been sent as a separate patch, since it is a pure bugfix. Nevertheless this patchset depends on this patch, thus I decided to fold it here as well. Host capabilities for SDR12 and SDR25 needs to be set to enable support, but that will be handled outside this patchset.
