The FP6 sensor suite (QMC6308 magnetometer @ 0x2c, SPL07 barometer @ 0x76, STK3BCx ALS/proximity @ 0x48) sits on an I2C bus wired to TLMM gpio153/gpio154. Those pads are eGPIOs with no AP serial-engine function: on the stock OS the bus is driven by an island QUP owned by the Snapdragon Sensor Core on the ADSP. From the AP they are only usable as software GPIOs, so describe the bus as i2c-gpio, and add the QMC6308 magnetometer node: powered from the always-on vreg_l10b (per the schematics), mount matrix from the vendor SSC registry (volcano_qmc630x_0.json .orient: sensor x -> device +y, sensor y -> device -x, z -> z), validated against Earth's field with a four-point cardinal rotation.
