Subject: [PATCH 2/8] ARM: dts: dra7xx-clocks: Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck

From: Keerthy <j-keerthy@...com>

Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck
from dpll_pcie_ref_ck.

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 is dpll_pcie_ref_m2ldo_ck which is also the input
of apll.
