Subject: [PATCH v1 0/6] clk: sunxi-ng: Allwinner D1 clock support

This series adds support for the D1's CCU and R_CCU.

I attempted to hook up clock parents the "right" way, not using global
names. To accomplish that, I added several new macros. I am open to
comments on this approach. It looks a bit messier, but seems like it
could be less prone to errors.


Samuel Holland (6):
  dt-bindings: clk: Add compatibles for D1 CCUs
  clk: sunxi-ng: div: Add macros using clk_parent_data and clk_hw
  clk: sunxi-ng: mp: Add macros using clk_parent_data and clk_hw
  clk: sunxi-ng: mux: Add macros using clk_parent_data and clk_hw
  clk: sunxi-ng: gate: Add macros for gates with fixed dividers
  clk: sunxi-ng: Add support for the D1 SoC clocks
