The idea for this series was born back from Dublin (ELCE 2022) after
having attended the talk entitled "Updating and Modernizing Clock
Drivers" held by Chen-Yu Tsai and the availability of a board with
imx8mn SOC.

This series aims to setup all imx8mn's clocks from the device tree and
remove the legacy setup code with hardwired parameters.

I am well aware that the series lacks patches for the DT bindings. The
effort up to this point has been important and so I thought I'd ask for
feedback from the community before proceeding to implement them. If it
is positive I will add the DT binding patches starting from version 2.

The series has been tested on the BSH SystemMaster (SMM) S2 board:
