    pwm: fsl-ftm: Added a dedicated IP interface clock · 82a9c55a
    shenwei.wang@nxp.com authored
    The current driver assumes that the ftm_sys clock works as one of the
    clock sources for the IP block as well as the IP interface clock. This
    assumption does not apply any more on the latest i.MX8x SoC family. On
    i.MX8x SoCs, a dedicated IP interface clock is introduced and it must be
    enabled before accessing any FTM registers. Moreover, the clock can not
    be used as the source clock for the FTM IP block. This patch introduces
    the ipg_clk as the dedicated IP interface clock and by default it is the
    same as the ftm_sys clock if not specified.
