The goal of this series was to add missing I2C bindings for BLSP_I2C1,
BLSP_I2C3, and BLSP_I2C5. But while working on this, I noticed some
styling issues and decided to tackle them in the same patchset, mostly
because they touch the same files and the same people will be involved
for the review. Let me know if you'd rather see them sent separately.
First patch reindents the wcd_codec block in pm8916.dtsi with respect
to the kernel standards.
Second patch and third patch makes existing I2C more in sync with the
rest of the bindings by dropping assignments to a property that doesn't
take a value, and by making their style matches thus of SPI bindings.
Last patch add bindings of I2C cores 1, 3, and 5.
Damien Riegel (4):

Indentation did not respect kernel standards, so fix that for the usual
indent with tabs, align with spaces. While at it, remove some empty
lines before and after the closing parenthesis of this block.

Drop assignments to bias-disable as the documentation [1] states that
this property doesn't take a value. Other occurrences of this property
respect that.

* [PATCH 3/4] arm64: dts: qcom: msm8916: normalize I2C bindings

The QUP core can be used either for I2C or SPI, so the same IP is mapped
by a driver or the other. SPI bindings use a leading 0 for the start
address and a size of 0x600, I2C bindings don't have the leading 0 and
have a size 0x1000.
To make them more similar, add the leading 0 to I2C bindings and changes
the size to 0x600, as the driver only accesses registers up to address
0x408. Also align the second entry of the clocks array.

pinconf is typically board specific, so please leave these out from the
base dtsi.

Please omit the pinctrl-* properties from the base dtsi (when it's not
hard coded things for the platform).

I don't mind dropping that, but pinconf for i2c{2,4,6} is already in
msm8916-pins.dtsi, so we should either drop them all, or add pinconf for
i2c{1,3,5} for consistency. And if I read the pinctrl driver correctly,
I2C cannot be routed to other pins, the only properties that users may
want to modify are drive-strength and bias. Let me know which option you
prefer.

You're right, this needs to be consistent. So I would like us to update
the existing nodes,

I discussed the matter with my colleagues and we concluded that we want
to keep the muxing in the platform.dtsi and move the specification of
the electrical properties (pinconf) to the board.dts(i).
We did discuss having some "default values" in the platform file, but
pushing these down to the board file gives an indication to others that
these values are board specific.
PS. If you're willing to provide a patch for the existing nodes I would
be happy to review this as well!

Okay that makes sense. I'll work on a patchset to do that.
