Subject: Re: [PATCH v4 1/2] dt-bindings: spi: add loongson spi

This patch need depend on
https://lore.kernel.org/all/20230323025229.2971-1-zhuyinbo@loongson.cn/
then the spi yaml file will build successful, if no this clock patch 
that spi yaml will build fail, so please test it that base on above 
clock patch.
