[PATCH v2 3/3] arm64: dts: amlogic: t7: Add core clock to PWM controller nodes
From: Ronald Claveau via B4 Relay
Date: Fri Sep 25 2026 - 11:22:55 EST
From: Ronald Claveau <linux-kernel-dev@xxxxxxxx>
Describe the system clock of each PWM controller (CLKID_SYS_PWM_*) as a
third clock, and add the clock-names property expected by the updated
binding: "channel-a", "channel-b" and "core".
