  clk: Add API to get index of the clock parent (2019-11-11 13:59:35 +0100)

This is an updated pull request that contains the revised version of the
new API as discussed with Stephen in this thread:

----------------------------------------------------------------
clk: Changes for v5.5-rc1

Contains a single core API addition that allows clock providers to query
the parent index for a given struct clk_hw. This is used to implement
suspend/resume support on Tegra SoCs.

  clk: tegra: Fix build error without CONFIG_PM_SLEEP (2019-11-11 14:53:05 +0100)

This updated pull request contains changes needed for the updated API to

Stephen.

Thanks,

clk: tegra: Changes for v5.5-rc1

The bulk of these changes implement suspend/resume support for Tegra210.
In addition, some of the SOR clocks on earlier Tegra generations are
reimplemented to more closely match the implementation on later chips,
which in turn makes it possible to handle HDMI and DP support in a more
unified way.

Thanks. Pulled into clk-next. I noticed this error from static checker.

drivers/clk/tegra/clk.c:241 tegra_clk_init() error: double free of 'periph_clk_enb_refcnt'

And maybe that function can use struct_size() too instead of kcalloc
with a multiply?

That's a good catch! Sowjanya, could you please make a patch to fix it?

The struct_size() has a different purpose, it should be used when
structure is padded with a variable-size array at the end.
