Thanks for the review.
I will change like this:
=============
clocks:
items:
- description: bclk is the block clock.
clock-names:
items:
- const: bclk
required:
- compatible
- reg
- interrupts
- mediatek,larbs
- '#iommu-cells'
if:
properties:
compatible:
contains:
enum:
- mediatek,mt2701-m4u
- mediatek,mt2712-m4u
- mediatek,mt8173-m4u
then:
required:
- clocks
==============
If this is not right, please tell me.
(dt_binding_check is ok.)
