The series adds support for spread spectrum clocking for i.MX8MN PLLs (audio, video and DRAM). It has been tested for the video PLL on a board using i.MX8MN. The patches added in version 4, such as the dt-bindings and the driver for anatop, were inspired by the extensive email exchange from version 3: https://lore.kernel.org/imx/20241106090549.3684963-1-dario.binacchi@xxxxxxxxxxxxxxxxxxxx/ The series added spectrum spread support for the imx8mn platform only, but in case it was merged, confirming that the directives and suggestions made by the maintainers were correctly understood and implemented, I will extend this support to the imx8mm and imx8mp platforms as well.
