Hello,
This patchset adds external reset and wakeup support for CCS811 VOC
gas sensor. 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 v3:
* Added ccs811_set_wake(false) to all error paths before calling it actually
* Added Andy's reviewed-by tag
* Added comment for reset procedure and dropped error print for gpio request
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()
