[PATCH 3.12 14/82] mmc: sdhci-esdhc: Make 8BIT bus work

From: Jiri Slaby <hidden>
Date: 2015-08-24 09:34:03
Also in: 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: Joakim Tjernlund <redacted>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 8e91125ff3f57f15c6568e2a6d32743b3f7815e4 upstream.

Support for 8BIT bus with was added some time ago to sdhci-esdhc but
then missed to remove the 8BIT from the reserved bit mask which made
8BIT non functional.

Fixes: 66b50a00992d ("mmc: esdhc: Add support for 8-bit bus width and..")
