Hi Oleksij,

It changed in this commit:
commit fa28d8212ede9c533ae87a737571a9d3b3eebb29 Author: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Date: Fri Jul 10 07:19:37 2020 +0200
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.
