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: https://www.apertis.org/reference_hardware/imx8mn_bsh_smm_s2pro_setup Changes in v2: - Fix compiler warnings reported by kernel test robot.
