I'm working to convert these areas to normal "simple-bus" nodes, when that is complete then the name "clock" will be fine again here.

The name "clock" is not allowed for nodes, use "clock-controller" to remove the DTS check warning. Signed-off-by: Andrew Davis <afd@ti.com> --- arch/arm64/boot/dts/ti/k3-am64-main.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
