Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck
from dpll_pcie_ref_ck.
Why? Needs a better changelog also.
Figure 26-22. DPLL_PCIE_REF Functional Block Diagram in vE of DRA7xx ES1.0 TRM
shows the signal name for the output of post divider (M2) is CLKOUTLDO.
Figure 26-21. PCIe PHY Clock Generator Overview shows CLKOUTLDO is used as
input to apll mux.
So the actual output of dpll should be dpll_pcie_ref_m2ldo_ck instead of
dpll_pcie_ref_ck (which is the input of apll mux).
Yep, this is what I want to see in the changelog, so please repost. The
original changelog had no info on it whatsoever.

Thanks
