Subject: [PATCH 3/3] clk: at91: sama5d2: allow setting all PMC clock parents via DT
Date: Sun, 15 Mar 2020 19:38:06 +0100 [thread overview]
Message-ID: <590024802c809b02d93cb849e16a62f01963532a.1584296940.git.mirq-linux@rere.qmqm.pl> (raw)
In-Reply-To: <cover.1584296940.git.mirq-linux@rere.qmqm.pl>
We need to have clocks accessible via phandle to select them
as peripheral clock parent using assigned-clock-parents in DT.
PLLACK and AUDIOPLLCK were missing for sama5d2. Add them.
