This series improves the handling of clock and reset controls of
NVIDA Tegra ALSA drivers. Tegra HDA and AHUB drivers aren't handling
resets properly, which needs to be fixed in order to unblock other
patches
related to fixes on the reset controller driver since HDA/AHUB are bound
to fail once reset controller driver will be corrected. In particular
ALSA
drivers are relying on implicit de-assertion of resets which is done
by the
tegra-clk driver. It's not the business of the clk driver to touch resets
and we need to fix this because it breaks reset/clk programming sequences
of other Tegra drivers.

I wonder if this will help with the issues we saw when the tegra is
the i2s clock slave.

Probably no, this series shouldn't fix any of the current problems. I
will be surprised if it does.
