[PATCH 0/4] clk: si5351: Some fixes

[Sebastian Hesselbarth <sebastian.hesselbarth-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

For Si5351 clock driver, Michael Welling and Jean-Francois Moine reported
issues with recent v4.x kernels due to broken/missing/wrong parent clock
claming. This patch set now deals with the issues reported.

Patch 1 amends the binding documentation mention clock-names property
for the "xtal" and "clkin" parent clock inputs of Si5351 variants.

Patch 2 adds the clock-names property for the SolidRun CuBox using Si5351
with a fixed oscillator connected to "xtal" input.

Patch 3 reworks the way we claim parent clocks by using devm_clk_get()
for both DT and platform_data based registration. Also, properly check
for errors returned by devm_clk_get() and prepare/enable the parent clocks.

Patch 4 introduces a function to reset PLLs on rate change. This should
improve generated clock output stability. I currently have no scope at hand
to actually test that properly, so there may be more issues remaining.

@Michael, Jean-Francois: Please test and report if there are still
issues remaining.

Sebastian
