From a994b58f9d1163c4f559bd169721f0fc15866919 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 20 Apr 2025 18:47:59 +0200 Subject: [PATCH] ARM: dts: amlogic: meson8b: fix reference to unknown/untested PWM clock Device-tree expects absent clocks to be specified as <0> (instead of using <>). This fixes using the FCLK4/FCLK3 clocks as they are now seen at their correct index (while before they were recognized, but at the correct index - resulting in the hardware using a different clock than what the kernel sees).
