[PATCH AUTOSEL 4.19 31/44] clk: meson-axg: pcie: drop the mpll3 clock parent

From: Sasha Levin
Date: Tue Nov 13 2018 - 01:03:57 EST


From: Yixun Lan <yixun.lan@xxxxxxxxxxx>

[ Upstream commit 69b93104c7ec5668019caf5d2dbfd0e182df06db ]

We found the PCIe driver doesn't really work with
the mpll3 clock which is actually reserved for debug,
So drop it from the mux list.
