Subject: [PATCH 0/6] mmc: add support for sdhci 4.0
Date: Fri, 8 Jun 2018 16:18:07 +0800 [thread overview]
Message-ID: <1528445893-14530-1-git-send-email-zhang.chunyan@linaro.org> (raw)
>From the SD host controller version 4.0 on, SDHCI implementation either
is version 3 compatible or version 4 mode. This patch-set covers those
changes which are common for SDHCI 4.0 version, regardless of whether
they are used with SD or eMMC storage devices.
This patchset also added a new sdhci driver for Spreadtrum's controller
which supports v4.0 mode.
This patchset has been tested on Spreadtrum's mobile phone, emmc can be
initialized, mounted, read and written, with these changes for common
sdhci framework and sdhci-sprd driver.
