Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk fixes from Stephen Boyd:
 "Three clk driver fixes to close out the release

   - Fix a divider calculation breaking boot on Broadcom bcm2835

   - Fix HDMI output on Tanix TX6 mini board by reverting a patch

   - Fix clk_set_rate_range() calls on at91 by considering the range
     while calculating the divisor"

* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
  clk: at91: generated: consider range when calculating best rate
  Revert "clk: sunxi-ng: sun6i-rtc: Add support for H6"
  clk: bcm2835: fix bcm2835_clock_choose_div
