Sorry for the delay, this should fix it:

@@ -754,7 +769,7 @@ static int rp1_pll_divider_set_rate(struct clk_hw *hw,
        clockman_write(clockman, data->ctrl_reg, sec);
 
        /* must sleep 10 pll vco cycles */
-       ndelay(10ULL * div * NSEC_PER_SEC / parent_rate);
+       ndelay(div64_ul(10ULL * div * NSEC_PER_SEC, parent_rate));
 
        sec &= ~PLL_SEC_RST;
        clockman_write(clockman, data->ctrl_reg, sec);

should I send a new patch with this fix only (against linux-next or stblinux/next?)
or Florian is it better if you make the change in your next branch directly?

Many thanks,
Andrea
