Subject: [PATCH V2 0/7] mmc: add support for sdhci 4.0
Date: Fri, 15 Jun 2018 10:04:08 +0800 [thread overview]
Message-ID: <1529028255-6022-1-git-send-email-zhang.chunyan@linaro.org> (raw)
From: Chunyan Zhang <chunyan.zhang@spreadtrum.com>
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 v1:
* Addressed comments from Ulf:
- Add dt-bindings for Spreadtrum sdhci;
- Use assigned-clocks* DT bindings to set default source of sdio clock;
- Removed unuseful print;
- Removed two functions which are not used;
- Add back the missing pm_runtime_put_autosuspend() after adding sdhci host.
* Changed Spreadtrum sdhci driver name to sdhci-sprd.
