The programming sequence for voltage switching, tuning is followed from AM572x TRM http://www.ti.com/lit/ug/spruhz6j/spruhz6j.pdf (Similar to all AM57x/DRA7x SoCs). The patch series also implements workaround for errata published in http://www.ti.com/lit/er/sprz429l/sprz429l.pdf patches are created on top of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git next Changes from v3: *) Fixed Adrian's comment on error handling when __sdhci_add_host() fails *) Used Adrian's patches for programming SW timeout value. Changes from v2: *) Patches in v2 already applied to mmc -next are dropped from the series. *) Changed SW timeout logic as per Adrians's suggestion *) Validated SDIO with the current patches (added a couple of fixes found while adding SDIO support). *) Used soc_device_match() instead of pdata-quirks as per Tony's suggestions. Changes from v1: *) Only poll on DAT0 and DATI for card_busy status *) Cleanup iodelay patch as suggested by Tony. *) Added quirk to disable HW timeout *) Use the existing data timer but program a relatively accurate SW timeout value (Impacts all platforms) *) Fix a bug in sdhci which was using data_timer for non data line commands Adrian Hunter (2): mmc: sdhci: Add quirk to disable HW timeout mmc: sdhci: Factor out target_timeout calculation Kishon Vijay Abraham I (10): mmc: sdhci-omap: Fix when capabilities are obtained from SDHCI_CAPABILITIES reg mmc: sdhci-omap: Remove setting ADMA capability in driver mmc: sdhci-omap: Workaround for Errata i843 mmc: sdhci-omap: Invoke sdhci_get_of_property to read sdhci dt properties mmc: sdhci: Disable HS200 mode if controller can't support 1.8v mmc: sdhci: Program a relatively accurate SW timeout value mmc: sdhci-omap: Workaround for Errata i834 dt-bindings: sdhci-omap: Add K2G specific binding mmc: sdhci-omap: Add support for MMC/SD controller in k2g SoC mmc: sdhci-omap: Add sdhci_omap specific ops for enable_sdio_irq .../devicetree/bindings/mmc/sdhci-omap.txt | 2 + drivers/mmc/host/sdhci-omap.c | 81 ++++++++++-- drivers/mmc/host/sdhci.c | 123 ++++++++++++++---- drivers/mmc/host/sdhci.h | 15 +++ include/linux/mmc/host.h | 1 + 5 files changed, 191 insertions(+), 31 deletions(-) -- 2.17.0
