Subject: [PATCH 0/3] Add Reset and Wakeup support for CCS811

From: Manivannan Sadhasivam <>


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.
