[PATCH RESEND] CLK: ARC: Set initial pll output frequency specified in device tree

2017-11-14 Thread Eugeniy Paltsev
Add option to set initial output frequency of plls via "clock-frequency" property in pll's device tree node. This frequency will be set while pll driver probed. The usage example is setting CPU clock frequency on boot See discussion: https://www.mail-archive.com/linux-snps-arc@lists.infradead.org/
