That isn't logical, but maybe later patches make it clear...cc.mult has to be reloaded to original value each time CPTS is registered(restarted) as it can be modified by cpts_ptp_adjfreq(). While cc.shift is static.
Will it ok if i will add comment here and re-send series? -- regards, -grygorii -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
