Subject: [PATCH V6 0/9] mmc: add support for sdhci 4.0
Date: Fri, 24 Aug 2018 17:20:19 +0800 [thread overview]
Message-ID: <1535102428-20332-1-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.
This patchset is based on the unmerged patch: https://lkml.org/lkml/2018/8/20/140
Changes from V5:
- Added SDHCI_QUIRK2_BROKEN_32BIT_BLK_CNT;
- Removed sdhci_enable_cmd23();
- Added setting SDHCI_ARGUMENT2 for CMD23 in v4_mode;
- Clear SDHCI_CMD23_ENABLE when not using CMD23;
- Moved disabling auto-CMD23 to sprd sdhci driver;
- Added sdhci_sprd_request() function to hook to mmc_host_ops.request.
