For which variants/compatibles it is optional? Add allOf:if:then restricting it. Best regards, Krzysztof

If add restricting on this, may not easy to maintain. Does this acceptable? Thanks Xiangsheng Hou

I don't think it is not easy to maintain. We have it in many, many bindings... Best regards, Krzysztof

1. add mt7986 IC bindings 2. add optional nfi_hclk property which needed for mt7986 Signed-off-by: Xiangsheng Hou <xiangsheng.hou@mediatek.com> --- .../devicetree/bindings/spi/mediatek,spi-mtk-snfi.yaml | 6 ++++++ 1 file changed, 6 insertions(+)
