    OK, seeing how you got this -- I should have tested the kernel build with 
only R8A7743 enabled... sorry about that. :-<
    I probably shouldn't have used rcar_gen2_timer_init() in the 1st place...

    The problem is we're not going to use this driver on RZ/G SoCs... The 
newer rcar2-cpg-mssr.c will be used instead -- I submitted the patches for 
that before ELC-E...
