This is the first step in deprecating omap_hsmmc driver completely and moving to sdhci-omap driver which uses the sdhci library. This series adds a new SDHCI quirk to indicate MMC_RSP_136 has CRC (since sdhci in OMAP has CRC) Apart from the quirk, sdhci-omap has it's own callbacks to set_clock (clock divider programming is different from generic sdhci) , set_power, set_bus_width, set_bus_mode and platform_send_init_74_clocks. These callback functions are implemented based on omap_hsmmc driver. The sdhci-omap driver supports only the high speed mode and UHS/HS200 mode will be added in a later series. It has been tested only in boards having DRA7 SoCs like dra7-evm, dra72-evm, am571x-idk, am572x-idk, am57xx-evm. (Tested only eMMC and SD. SDIO support will be added later). The plan is to fully convert DRA7 SoC to use SDHCI driver and then convert other legacy platforms to use SDHCI. Next Steps: *) Add UHS support to sdhci-omap *) Add SDIO support *) Add support for older TI platforms Changes from v1: *) Remove the quirks and instead use sdhci_omap specific callbacks for set_power, set_busmode etc. *) Add a patch from Adrian to tidy reading 136-bit responses I've also pushed the entire series along with dependent dt patches @ https://github.com/kishon/linux-wip.git sdhci_omap_v1 (in case someone wants to test) Adrian Hunter (1): mmc: sdhci: Tidy reading 136-bit responses Kishon Vijay Abraham I (4): mmc: sdhci: Add quirk to indicate MMC_RSP_136 has CRC dt-bindings: ti-omap-hsmmc: Document new compatible for sdhci omap mmc: sdhci-omap: Add OMAP SDHCI driver MAINTAINERS: Add TI OMAP SDHCI Maintainer .../devicetree/bindings/mmc/ti-omap-hsmmc.txt | 1 + MAINTAINERS | 6 + drivers/mmc/host/Kconfig | 12 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/sdhci-omap.c | 629 +++++++++++++++++++++ drivers/mmc/host/sdhci.c | 31 +- drivers/mmc/host/sdhci.h | 2 + 7 files changed, 672 insertions(+), 10 deletions(-) create mode 100644 drivers/mmc/host/sdhci-omap.c -- 2.11.0 -- 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
