The PL022's actual input is named SSPCLK, not SPICLK, so why should a driver which wants to look up that clock by name expect to look for "spiclk"?

It's the DT which is at the fault of defining spiclk instead of sspclk and need to be fixed in DT itself. I didn't take a look at pl022 doc and acted on the basis of DT info. Moreover, DT also uses sspclk and SSPCLK names interchangeably which are anyway same. This also require updation to follow single convention. Appreciate your comments and valuable inputs.
