Add Xilinx AMS driver which is used for Xilinx's ZynqMP AMS controller. This AMS driver is used to report various interface voltages and temperatures across the system. This driver handles AMS module including PS-Sysmon & PL-Sysmon. The binding documentation is added for understanding of AMS, PS, PL Sysmon Channels. Changes in v2: - Added documentation for sysfs (Patch-2) - Addressed code style review comments - Patch-2 (Now it is Patch-3) - Arranged the includes in alphabetical order - Removed the wrapper 'ams_pl_write_reg()' and used writel instead - Removed the unnecessary delay of 1ms and used polling of EOC instead - Removed spin_lock and used mutex only. - Used request_irq() instead of devm_request_irq() and handled respective error conditions - Moved contents of xilinx-ams.h to inline with xilinx-ams.c - Patch-1 - Addressed Documentation style comments Manish Narani (4): dt-bindings: iio: adc: Add Xilinx AMS binding documentation iio: Documentation: Add Xilinx AMS sysfs documentation iio: adc: Add Xilinx AMS driver arm64: zynqmp: DT: Add Xilinx AMS node .../ABI/testing/sysfs-bus-iio-adc-xilinx-ams | 246 ++++ .../devicetree/bindings/iio/adc/xilinx-ams.txt | 180 +++ arch/arm64/boot/dts/xilinx/zynqmp.dtsi | 26 + drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/xilinx-ams.c | 1337 ++++++++++++++++++++ 6 files changed, 1800 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-adc-xilinx-ams create mode 100644 Documentation/devicetree/bindings/iio/adc/xilinx-ams.txt create mode 100644 drivers/iio/adc/xilinx-ams.c -- 2.1.1
