    Subject[PATCH 3/3] arm64: dts: qcom: sm7225-fairphone-fp4: Add AW8695 haptics
    Date
    Add a node for the haptics driver found on the phone.

    Signed-off-by: Luca Weiss <luca.weiss@fairphone.com>

    This patch depends on the i2c10 node introduced in this patch:
    https://lore.kernel.org/linux-arm-msm/20220408114205.234635-2-luca.weiss@fairphone.com/

    For reference, the dt properties are based on the following properties
    from the original vendor driver:

    vib_f0_pre = < 2350 >;
    => awinic,f0-preset = <2350>;

    vib_f0_coeff = < 260 >;
    => awinic,f0-coefficient = <260>;

    vib_f0_cali_percen = < 7 >;
    => awinic,f0-calibration-percent = <7>;

    vib_cont_drv_lev = < 125 >;
    => awinic,drive-level = <125>;

    vib_f0_trace_parameter = < 0x05 0x03 0x02 0x0f >;
    => awinic,f0-detection-play-time = <5>;
    => awinic,f0-detection-wait-time = <3>;
    => awinic,f0-detection-repeat = <2>;
    => awinic,f0-detection-trace = <15>;

    vib_bstdbg = < 0x30 0xeb 0xd4 0 0 0 >;
    => awinic,boost-debug = /bits/ 8 <0x30 0xeb 0xd4>;

    vib_tset = < 0x12 >;
    => awinic,tset = /bits/ 8 <0x12>;

    vib_r_spare = < 0x68 >;
    => awinic,r-spare = /bits/ 8 <0x68>;

    vib_bemf_config = < 0x10 0x08 0x03 0xf8 >;
    (0x10 << 8) | 0x08
    => awinic,bemf-upper-threshold = <4104>;
    (0x03 << 8) | 0xf8
    => awinic,bemf-lower-threshold = <1016>;
