Subject: [PATCH V7 0/9] mmc: add support for sdhci 4.0
Date: Wed, 29 Aug 2018 15:02:55 +0800 [thread overview]
Message-ID: <1535526184-32718-1-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.
Changes from V6:
- Rebased to the next branch of Ulf' mmc tree;
- Replaced SDHCI_QUIRK2_BROKEN_32BIT_BLK_CNT with SDHCI_QUIRK2_USE_32BIT_BLK_CNT,
also added a comment to its definition;
- Added a 'flags' in sprd_host for recovering host->flags in mmc_host_ops.request.
