Merge tag 'sunxi-clk-for-4.16-2' of https://git.kernel.org/pub/scm/li…

…nux/kernel/git/sunxi/linux into clk-allwinner

Pull Allwinner clock changes from Chen-Yu Tsai:

 - Fix hardware description for the DE2 clocks on the A64 and H5 SoCs
 - Support DE2 clocks on the H3
 - Fix description for the TCON1 clock on A83T

All these are non-critical, as they have no users.

* tag 'sunxi-clk-for-4.16-2' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux:
  clk: sunxi-ng: a83t: Add M divider to TCON1 clock
  clk: sunxi-ng: fix the A64/H5 clock description of DE2 CCU
  clk: sunxi-ng: add support for Allwinner H3 DE2 CCU
  dt-bindings: fix the binding of Allwinner DE2 CCU of A83T and H3
