If the DTS is correct, please explain why bindings are wrong. Thanks Krzysztof for pointing it out. So far I was wondering spiclk clock-name was the only culprit there and had different perception w.r.t number of clocks. Anyway, below reference is from pl022 point of view: https://documentation-service.arm.com/static/5e8e3bc7fd977155116a936d?token= https://developer.arm.com/documentation/ddi0194/h/functional-overview/primecell-ssp-operation/clock-ratios The reference no where mention that single clock can exist. So far Amd seattle and LG platforms don't comply with binding and define single clock which require updations. So now from bindings perspective, I am looking forward to keep only one notation of sspclk and will respin a patch. Kindly provide comments on the same.
