I'm using similar binding (different clock and interrupt names, but otherwise  
same) for quiet some time now on LibreELEC with ARM proprietary userspace and 
kernel space driver (32-bit GBM version) and it works well.

It's true that I'm using OPP table, but most (if not all) of the time GPU is 
set to lowest setting as there is not much to do when rendering GUI.

Best regards,
Jernej
