[PATCH v2 03/15] clk: sunxi-ng: mp: provide wrapper for setting feature flags
Posted by Andre Przywara 10 months, 1 week ago
So far our sunxi clock instantiation macros set the required flags
depending on the clock type, but the new "dual divider MP clock"
requires us to pass that piece of information in by the user.

Add a new wrapper macro that allows to specify a "features" field, to
allow marking those dual-divider clocks accordingly.
