From: Michał Mirosław Date: Mon, 4 May 2020 22:37:57 +0000 (+0200) Subject: clk: at91: allow setting all PMC clock parents via DT X-Git-Tag: v5.15~3627^2~7^6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03a1ee1dad0e39390ca397fff0cf84a3b1de1beb;p=platform%2Fkernel%2Flinux-starfive.git clk: at91: allow setting all PMC clock parents via DT We need to have clocks accessible via phandle to select them as peripheral clock parent using assigned-clock-parents in DT. Add support for PLLACK/PLLBCK/AUDIOPLLCK clocks where available.
