It changed in this commit:

    ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files

    The imx-pwm driver supports 3 cells and this is the more flexible setting.
    So use it by default and overwrite it back to two for the files that
    reference the PWMs with just 2 cells to minimize changes.

    This allows to drop explicit setting to 3 cells for the boards that already
    depend on this. The boards that are now using 2 cells explicitly can be
    converted to 3 individually.
