Use pll_ref instead of pll_re_vco as the pll_e parent on Tegra114 and Tegra124. Also add a pll_ref table entry for pll_e for Tegra114.Why? What benefit does this give, or what bug does this fix?Otherrwise Tegra114 will crash on boot.Sigh. For what reason?pll_re_vco having an unsupported rate of 300Mhz. My guess is that it depends on the bootloader if you will see this. I'm fairly sure I verified this on my dalmore in helsinki and it worked, but it failed on Paul's test setup.
OK, so this is primarily a SW issue, because pll_e's freq_table simply doesn't have an entry for input frequency 300MHz. Can you make sure the commit description explains that?
