The first part of ongoing work to convert the sunxi-ng clk driver from
using global clock name strings to describe clk parenting, to having
direct struct clk_hw pointers, or local names based on clock-names from
the device tree binding.
This is based on Stephen Boyd's recent work allowing clk drivers to
specify clk parents using struct clk_hw * or parsing DT phandles in the
clk node.
This series can be split into a few major parts:
1) The first patch is a small fix for clk debugfs representation.
2) A bunch of CLK_HW_INIT_* helper macros are added. These cover the
situations I encountered, or assume I will encounter, such as single
internal (struct clk_hw *) parent, single DT (struct clk_parent_data
.fw_name), multiple internal parents, and multiple mixed (internal +
DT) parents. A special variant for just an internal single parent is
added, CLK_HW_INIT_HWS, which lets the driver share the singular
list, instead of having the compiler create a compound literal every
time. It might even make sense to only keep this variant.
3) A bunch of CLK_FIXED_FACTOR_* helper macros are added. The rationale
is the same as the single parent CLK_HW_INIT_* helpers.
4) Bulk conversion of CLK_FIXED_FACTOR to use local parent references,
either struct clk_hw * or DT .fw_name types, whichever the hardware
requires.
5) The beginning of SUNXI_CCU_GATE conversion to local parent
references. This part is not done. They are included as justification
and examples for the shared list of clk parents case.
