The DT definition is added for STiH415 and STiH416 SoCs on B2000 and B2020 boards. The series has been tested working on STiH416-B2020 board. It applies on top of v3.12-rc5. Changes since v4: - Fixed IRQ flags to level high triggering as reported by Stephen Gallimore - Revert back to generic DT properties for Anti-glitch filtering. Their DT binding documentation will be updated when i2c DT binding docuementation will be created (In Wolfram's ToDo list) - Rebased on v3.12-rc5 Changes since v3: - Switch back to vendor specific DT properties regarding the anti-glitch filter configuration, as this IP is the only one having such a filter - Add DT binding documentation regarding pinctrl-related properties - Move recommended properties to optional properties in DT binding documentation - Rebased on v3.12-rc4 Changes since v2: - Create generic DT property for Anti-glitch filtering configuration - Sort i2c-st entries in Makefile and Kconfig - Various cosmetics changes - Return IRQ_NONE in case of spurious interrupt - Use INIT_COMPLETION instead of init_completion in st_i2c_xfer_msg - Simplify st_i2c_xfer as proposed by Wolfram - Fix PM ops issues - Change author name to myself and fix license to GPL v2 - Include .h file content into the .c file Changes since v1: - Anti-glitch filtering simplified (Only HW Anti-glitch is kept) - Update I2C timings to comply with I2C specification - Handle spurious interrupts properly - DT binding updates taking into account Stephen's comments - Use "clock-names" property to comply with GCF - DT cosmetic changes reported by Lee and Gabriel Signed-off-by: Maxime Coquelin Maxime Coquelin (4): i2c: busses: i2c-st: Add ST I2C controller ARM: STi: Supply I2C configuration to STiH416 SoC ARM: STi: Supply I2C configuration to STiH415 SoC ARM: STi: Add I2C config to B2000 and B2020 boards Documentation/devicetree/bindings/i2c/i2c-st.txt | 38 + arch/arm/boot/dts/stih415-pinctrl.dtsi | 36 + arch/arm/boot/dts/stih415.dtsi | 53 ++ arch/arm/boot/dts/stih416-pinctrl.dtsi | 35 + arch/arm/boot/dts/stih416.dtsi | 53 ++ arch/arm/boot/dts/stih41x-b2000.dtsi | 9 + arch/arm/boot/dts/stih41x-b2020.dtsi | 22 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-st.c | 867 ++++++++++++++++++++++ 10 files changed, 1124 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-st.txt create mode 100644 drivers/i2c/busses/i2c-st.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
