As per AM57x TRM SPRUHZ6, October 2014, Section 29.1.3 Table 29-4. source signal as L4PER2_L3_GICLK but it is actually equal to L4PER2_L3_GICLK/2. l4_root_clock_div is fixed-factored clock equal to L4PER2_L3_GICLK/2 (l3_iclk_div/2 in Linux clock dt). The TRM does'nt show factor of by 2. I will forward you an internal documentation that talks about this. I also measured the frequencies of PWM waveforms using oscilloscope and it matches above observation. I will update the patch description in v2.
