It is available on SAMA5D2. A firmware and a configuration file describing the topology and the parameters of the sensor are loaded when probing the driver. Changes: - v2: - reorder patches to get the bindings documentation in first - remove the header from the uapi since it may change in the future. Declare only the few structures needed in the driver. - add this driver to the sama5_defconfig Ludovic Desroches (5): dt-bindings: input: Add Atmel PTC subsystem bindings input: misc: introduce Atmel PTC driver MAINTAINERS: add Atmel PTC entries ARM: dts: at91: sama5d2: add PTC subsystem device ARM: at91/defconfig: add PTC driver to sama5_defconfig .../devicetree/bindings/input/atmel,ptc.txt | 67 ++ MAINTAINERS | 7 + arch/arm/boot/dts/sama5d2.dtsi | 16 + arch/arm/configs/sama5_defconfig | 2 + drivers/input/misc/Kconfig | 12 + drivers/input/misc/Makefile | 1 + drivers/input/misc/atmel_ptc.c | 723 +++++++++++++++++++++ 7 files changed, 828 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/atmel,ptc.txt create mode 100644 drivers/input/misc/atmel_ptc.c -- 2.9.0
