ls1012a has separate input root clocks for core PLLs versus the platform
PLL, with the latter described as sysclk in the hw docs.
Update the qoriq-clock binding to allow a second input clock, named
"coreclk". If present, this clock will be used for the core PLLs.

If anything changed, I take it over and dropped the 2/3 patch in your original patch set to speed up the merge, which I think so. This patch set blocks other patches and 20 days passed, no any action on it. We can't account on you to push it. That's why I take it over and resend it.
