Cover letter [PATCH v2 0/2] iio: humidity: si7020: Check device property for skipping reset in probe
I2C commands issued after the SI7020 is starting up or after reset can potentially upset the startup sequence. Therefore, the host needs to wait for the startup sequence to finish before issuing further i2c commands. This is impractical in cases where the SI7020 is on a shared bus or behind a mux, which may switch channels at any time (generating I2C traffic). Therefore, check for a device property that indicates that the driver should skip resetting the device when probing.
