So the ADXL345 actually wont be driven by kernel. The SPI connection is enabled so that klipper (3d printer firmware) can be told to look for ADXL345 at this SPI and use it on its own. Klipper will initialize and communicate with the ADXL on its own. > = >> +}; >> + >> +&uart0 { >> + pinctrl-names =3D "default"; >> + pinctrl-0 =3D <&uart0_ph_pins>; >> + status =3D "okay"; >> +}; > = > = > = > = _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
