[PATCH v3 3/3] arm64: dts: amlogic: a1-c3-s4-t7: Add core clock to PWM controller nodes

From: Ronald Claveau via B4 Relay

Date: Sun Sep 27 2026 - 10:29:20 EST

From: Ronald Claveau <linux-kernel-dev@xxxxxxxx>

Describe the system clock of each PWM controller as a third clock,
and add the clock-names property expected by the updated binding:
"channel-a", "channel-b" and "core".
