The nRESET and nWAKE pins available on the device are utilised to provide these functionalities. The patchset has been validated using CCS811 connected to STM32MP1 based board over I2C. While at it, the devicetree yaml binding and OF match table for this sensor are also added. Thanks, Mani Changes in v2: * Fixed DT binding schema and switched to dual license (GPL/BSD) * Returned actual error code from devm_gpiod_get_optional() * Dropped of.h include and of_match_ptr() Manivannan Sadhasivam (3): dt-bindings: iio: chemical: Add binding for CCS811 VOC sensor iio: chemical: Add support for external Reset and Wakeup in CCS811 iio: chemical: Add OF match table for CCS811 VOC sensor .../bindings/iio/chemical/ams,ccs811.yaml | 51 ++++++++++ drivers/iio/chemical/ccs811.c | 95 +++++++++++++++++-- 2 files changed, 138 insertions(+), 8 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/chemical/ams,ccs811.yaml
