Revision 3a4347d82efdfcc5465b3ed37616426989182915 authored by Linus Torvalds on 30 October 2021, 16:55:46 UTC, committed by Linus Torvalds on 30 October 2021, 16:55:46 UTC 
Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
 
Pull clk fix from Stephen Boyd:
 "One fix for the composite clk that broke when we changed this clk type
  to use the determine_rate instead of round_rate clk op by default.
  This caused lots of problems on Rockchip SoCs because they heavily use
  the composite clk code to model the clk tree"

* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
  clk: composite: Also consider .determine_rate for rate + mux composites
