Like many similar chips, the DW9714 has a single VDD supply, but its I2C lines go through a level shifter to a 1.8V rail, and there is currently no place in DT to describe that rail so it gets enabled during I2C access to the device. As a stopgap, this series models it as an always-on, see the comment in the vreg_lvs1a_1p8 node). Direction agreed with Rob Herring and Mark Brown on IRC: - Modeling the level shifter itself is overkill as long as it is just a supply; modeling the connector would come first if needed. - Since each side of the shifter has its own supply, the proper solution is a generic 'bus-supply' property valid in both the I2C controller and device nodes. - Defining it per-device-schema would ideally use an I2C equivalent of spi-peripheral-props.yaml, which does not exist yet. The pragmatic interim is to define bus-supply in i2c-controller.yaml for both places and add 'bus-supply: true' to schemas that need it now (dw9714), deferring the peripheral-props question until more shared device properties accumulate. Once bus-supply exists, the regulator-always-on workaround in this DTS can be dropped. Signed-off-by: David Heidelberg --- Changes in v5: - There is secondary rear camera with the same AF. Tested with the camera (not upstreamed yet). - Verified the both rear cameras i2c addresses, added comment about it. - Link to v4: https://patch.msgid.link/20260810-dw9714v-v4-0-a227cb1d29bd@ixit.cz Changes in v4: - Updated DT bindings commit description.
