This patchset adds support of the Secure Digital Host Controller Interface compliant controller found in Qualcomm MSM chipsets. It has been tested on a APQ8074 Dragonboard. Changes from v5: - Driver is split into multiple patches - Do not initialize variables that are assigned later in code - Remove some useless comments - Use shorter variable names - Change pr_err() to dev_err() - Optimized sdhci_msm_setup_vreg() - Some code alignment fixes - Improved DT values sanity check - Added dev_dbg print for sdhci controller version in probe() - Added usleep_range() after SW reset - it can take some time - Added SDHCI_QUIRK_SINGLE_POWER_WRITE - power handled by PMIC - Renamed DT property vdd-io to vddio Changes from v4: - Simplified sdhci_msm_vreg_disable() and sdhci_msm_set_vdd_io_vol() - Use devm_ioremap_resource() instead of devm_ioremap() - Converted IS_ERR_OR_NULL to IS_ERR - Disable regulators in sdhci_msm_remove() - Check for DT node at the beginning in sdhci_msm_probe() - Removed more redundant code - Changes in some error messages - Minor fixes Changes from v3: - Allocate memory for all required structs at once - Added termination entry in sdhci_msm_dt_match[] - Fixed a missing sdhci_pltfm_free() in probe() - Removed redundant of_match_ptr - Removed the unneeded function sdhci_msm_vreg_reset() Changes from v2: - Added DT bindings for clocks - Moved voltage regulators data to platform data - Removed unneeded includes - Removed obsolete and wrapper functions - Removed error checking where unnecessary - Removed redundant _clk suffix from clock names - Just return instead of goto where possible - Minor fixes Changes from v1: - GPIO references are replaced by pinctrl - DT parsing is done mostly by mmc_of_parse() - Use of_match_device() for DT matching - A few minor changes Georgi Djakov (2): mmc: sdhci-msm: Initial SDHCI MSM driver documentation mmc: sdhci-msm: Initial support for MSM chipsets .../devicetree/bindings/mmc/sdhci-msm.txt | 70 +++ drivers/mmc/host/Kconfig | 13 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/sdhci-msm.c | 644 ++++++++++++++++++++ 4 files changed, 728 insertions(+) create mode 100644 Documentation/devicetree/bindings/mmc/sdhci-msm.txt create mode 100644 drivers/mmc/host/sdhci-msm.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
