I'd pretty much echo what Liam said - I'm not 100% sure from your description what the
patch is supposed to do and the code isn't particularly clear either. It *looks* like you're
trying to add a new clock source, but from the description this appears to be an
externally visible clock which makes it very unclear why you have to guess the frequency.
