This series of patches a support to the Atmel Flexcom, a wrapper which integrates an USART, a SPI controller and a TWI controller. Only one peripheral can be used at a time. The active function is selected though the Flexcom Mode Register. ChangeLog v11: - replace "GPLv2 only" by a proper license statement in "include/dt-bindings/mfd/atmel-flexcom.h" as suggested by Lee Jones. - remove usage of Linux specific macros for the values of the "atmel,flexcom-mode" property in the DT bindings documentation. - fix typo and reword some parts of the DT bindings documentation. v10: - add Acked-by from Nicolas Ferre v9: - go back to v5 (use the new "atmel,flexcom-mode" DT property). - fix the name of the spi node in the DT example: from spi@f8034400 to spi@400 - align the fields of the struct platform_driver atmel_flexcom_driver as suggested by Lee Jones. v8: - fix the name of the spi node in the DT example: from spi@f8034400 to spi@2,0 - use the return code of op_property_read_u32_index() instead of -EINVAL to report error. - add Acked-by from Nicolas Ferre v7: - read the operating mode from the very first u32 of the reg property from the first available child node (should be unique). - update the DT bindings documentation accordingly. v6: - select the operating mode according to the "compatible" DT property of the first available child node (should be unique). - remove the "atmel,flexcom-mode" DT property so the need of a header file defining macros for the possible values of this deprecated property. v5: - create a header file containing macros used by DT bindings - use numeric constants instead of strings to select the Flexcom mode - change the license to "GPL v2" - update the DT binding documentation to make it more readable and add references to USART, SPI and I2C DT binding documentations. remove the useless label in the Example section. - change the register prefix from FX_ to FLEX_ to match the Flexcom programmer datasheet. - rename some variables to make them more understandable. v4: - check clk_prepare_enable() return code in atmel_flexcom_probe() - add a commit message to the DT binding patch v3: - remove MODULE_ALIAS() - add Acked-by from Boris Brezillon and Alexandre Belloni v2: - enhance the documentation of DT bindings and change the way the "ranges" property is used. - replace __raw_readl() and __raw_writel() by readl() and writel(). - change the module license to "GPL" for v2 or later - print the selected flexcom mode after the hardware version Cyrille Pitchen (3): mfd: atmel-flexcom: create include file with macros used by DT bindings mfd: devicetree: add bindings for Atmel Flexcom mfd: atmel-flexcom: add a driver for Atmel Flexible Serial Communication Unit .../devicetree/bindings/mfd/atmel-flexcom.txt | 63 +++++++++++++ drivers/mfd/Kconfig | 11 +++ drivers/mfd/Makefile | 1 + drivers/mfd/atmel-flexcom.c | 104 +++++++++++++++++++++ include/dt-bindings/mfd/atmel-flexcom.h | 26 ++++++ 5 files changed, 205 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/atmel-flexcom.txt create mode 100644 drivers/mfd/atmel-flexcom.c create mode 100644 include/dt-bindings/mfd/atmel-flexcom.h -- 1.8.2.2 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
