[PATCH v2 7/8] clk: mediatek: mt7622: add missing clock PERIBUS_SEL clock

Christian Marangi ansuelsmth at gmail.com
Sat Aug 3 10:43:25 CEST 2024


Add missing PERIBUS_SEL clock to match upstream linux clk ID order. Also
convert pericfg to mux + gate implementation as now we have also mux on
top of gates.
