This muxer controls sub-buses that contains three Nuvoton NAU7802 ADCs and a NXP PCA955 GPIO expander. Support for these will be added eventually. Thanks, Maxime Changes from v2: - Fixed indentation of device tree nodes in patch 3 - Removed the address-cells and size-cells properties that are useless for now. Changes from v1: - Fixed indentation in patch 1 - Fixed arrays allocation for the dt bindings - Various fixes in the documentation Maxime Ripard (3): i2c: i2c-mux-gpio: Use devm_kzalloc instead of kzalloc i2c: mux: Add dt support to i2c-mux-gpio driver ARM: dts: cfa10049: Add the i2c muxer buses to the CFA-10049 .../devicetree/bindings/i2c/i2c-mux-gpio.txt | 81 +++++++++ arch/arm/boot/dts/imx28-cfa10049.dts | 24 +++ drivers/i2c/muxes/i2c-mux-gpio.c | 172 +++++++++++++++----- 3 files changed, 234 insertions(+), 43 deletions(-) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-mux-gpio.txt -- 1.7.9.5
