Subject: [PATCH v2 0/2] add the capability to disable st_lsm6dsx sensor-hub
Date: Sat, 13 Nov 2021 16:23:13 +0100 [thread overview]
Message-ID: <cover.1636816719.git.lorenzo@kernel.org> (raw)
Introduce the capability to disable sensorhub through a device-tree property
since since there are some configurations where users want to
explicitly disable sensor-hub auto-probing at bootstrap.
A typical configuration is when the sensorhub clock/data lines are connected
to a pull-up resistor since no slave sensors are connected to the i2c master.
If SDO/SA0 line is connected to the same pull-up resistor, when the driver
tries to probe slave devices connected on sensor-hub, it will force SDO/SA0
line to low, modifying the device i2c address.
Changes since v1:
- rename disable-shub property in disable-sensor-hub
- improve commit log
