FT5x06 DTS PROBLEM in 2.8B1 imx6dl colibri

Technical Support

Hi,
the ft5x06 driver with dts in colibri imx6 2.7B4 worked fine.
trying the new 2.8B1 with the same dts, the driver ft5x06 did not work (driver did not grep 0x38 device in i2c).
any idea ?

It seems that the driver cannot find the pinctrl node. Maybe that behavior changed with the new Linux 4.9 kernel. In general, it is recommended to carefully diff changes between the two versions as there might be breaking changes when moving to new NXP BSP kernels…

Try using a node around pinctrl_ft5x06, similar to GPIO:

touchscreen {
     pinctrl_ft5x06: ft5x06 {
             fsl,pin = <
             MX6QDL_PAD_EIM_A20__GPIO2_IO18    PAD_CTRL_HYS_PD /* SODIMM 97 */
             MX6QDL_PAD_EIM_A17__GPIO2_IO21    PAD_CTRL_HYS_PD /* SODIMM 101 */
             MX6QDL_PAD_EIM_A18__GPIO2_IO20    PAD_CTRL_HYS_PD /* SODIMM 103 */
        >;
    };
};
