Any comments? Thanks.
Sorry, I must have missed this on my last time through the patch queue. I see you've decimalized the fiper and max-adj properties, which is good... but does it really make sense for tmr-add? I'm not familiar with what this value represents, but the numbers look more natural as hex (e.g. 0xaaaaaaab versus 2863311531).

And here, you're changing the value of fsl,tmr-add and fsl,max-adj. Why? -Scott
