Subject: [PATCH 00/14] Control Quad SPI pinctrl better on Qualcomm Chromebooks
Date:   Thu, 23 Mar 2023 10:30:04 -0700

The main goal of this series is to do a better job of controling the
pins related to the "Quad SPI" IP block on Qualcomm Chromebooks. This
is essentially 'v2' of my previous attempt in the patch ("arm64: dts:
qcom: sc7180: Fix trogdor qspi pull direction") [1] but since it's
spiraled out a bit and there are no patches that are exactly the same
I've reset to v1.

The early patches in this series are just no-op cleanup patches that
can be applied. They're not terribly critical but since they are
"Fixes" I've listed them first.

The next patch in the series is a very simple and (hopefully)
non-controversial SPI patch. It can be applied independently if
anything else.

Next, we have a bunch of pinctrl patches (including the device tree
bindings related to them). I dunno what folks are going to think about
these. If everyone hates them, we can drop them and just change the
later patches in the series to use "input-enable" instead of
"output-disable". It feels ugly to me, but it maybe less upheval.

Next I removed the now-deprecated "input-enable" property from all
Chromebooks. None of them were necessary.

Finally, I did what I really wanted to do in the first place: attempt
to cleanup the pinctrl states of the Quad SPI. These patches have a
hard requirement on the pinctrl change.
