Hi Michael and Stephen, This patch set was acked by Rob Herring. Do you have any comments on them? BTW: Scott should stay in author, do I need to resend them with author changed or you can change it when applying? Regards, Yuantian

From: Tang Yuantian <redacted> 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.
