Commit 8bf5973a authored by Linus Torvalds's avatar Linus Torvalds

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

Pull clk fixes from Stephen Boyd:
 "A collection of fixes:

   - Make of_clk.h self contained

   - Fix new qcom DT bindings that just merged to match the DTS files

   - Fix qcom clk driver to properly detect DFS clk frequencies

   - Fix the ls1028a driver to not deref a pointer before assigning it"
