This series adds a driver for the ChromeOS snooping protection sensor (a.k.a. HPS) device, attached on the I2C bus. The sensor is a hardware-isolated module which reports a high-level presence signal, e.g., whether there is person in front of the computer or not.
The driver exposes the device to userspace as a character device, which can be used to send and receive messages to the sensor. The driver automatically turns power off to the sensor unless a process is
More information about HPS, its firmware and communication protocol can be found at https://chromium.googlesource.com/chromiumos/platform/hps-firmware.
