Cool idea, did that and added this line to drivers/net/ethernet/ti/cpts.c
(and noticed who wrote the file) as last line in
static void cpts_clk_init

properties define the clock constants:
nanoseconds = ticks * cpts
Hi Richard,
thank you for your prompt reply.

Hi linuxptp community,
I could put my hands on a TI AM5728 box (Elesar Titanium) running Linux arm
4.1.6-01294--g8406366 #6 SMP PREEMPT armv7l (Debian Jessy) and ethtool is
reporting this:
