[V6,0/9] Add Tegra234 HTE support

  This patch series mainly adds support for the Tegra234 HTE provider. In
addition, it addresses dt binding comments which prompted code
changes in the existing HTE provider driver without breaking the
Tegra194 provider. The comments raised concern how existing code
retrieves gpio controller node
(the node is used to help namespace conversion between HTE and GPIOLIB).
To help simplify that process, new DT property is suggested which adds
gpio controller node in the HTE provider binding as phandle property. To
conlude this patch series:
- adds Tegra234 HTE provider
- modifies existing provider code to address new dt binding for Tegra234
without breaking it for the Tegra194 chip.

The V1 patch series:
- Adds tegra Tegra234 HTE(timestamp) provider supports.
- Updates MAINTAINERS file for git tree, mail list fields.
- Updates devicetree and API documentations.
- Enables HTE subsystem, Tegra194 and Tegra234 HTE providers
by default in arm64 defconfig and dts files.

The V2 patch series:
- Changes in dt bindings to remove slices property
- Adds nvidia,gpio-controller dt property
- Add GTE node for the Tegra234

The V3 patch series:
- Re-arranged patches to have dt bindings first before its usage
- Addressed review comments regarding dt bindings

The V4 patch series:
- Logically divides dt binding and tegra HTE provider patches from v3
- Maintains backward compatibilty for the Tegra194

The V5 patch series:
- Reflect review comments for the patch
"dt-bindings: timestamp: Add nvidia,gpio-controller"
- Documentation changes including renaming of the file

The V6 patch series:
- Merges patch
"dt-bindings: timestamp: Add nvidia,gpio-controller" with the patch
"dt-bindings: timestamp: Add Tegra234 support"

All your emails miss PATCH prefix. Use `git format-patch` to generate
proper versioned patch. Stripping important part messes up with our
filters. We have quite a lot of emails, so proper filtering is important.

At this point I would even recommend kernel maintainers to get b4
into the workflow:
https://people.kernel.org/monsieuricon/sending-a-kernel-patch-with-b4-part-1

This tool will also implement other desired behaviours and version
the patch set for you.

I am gradually adopting it for my own work, using it all the time when
applying patches but also getting better at using it for submitting
them. It has a small overhead (like learning and memorizing the
subcommands) but once you get used to it, it is really helpful.

Yours,
Linus Walleij

I used to get this wrong as well because I didn't know (or perhaps it
didn't exist yet at the time) --reroll-count|-v and used to manually
override --subject-prefix.

My bad...excitement of sending the patch series got hold of me :) Now I have realized
it is been happening since the beginning. Since all the previous patches have been
sent without PATCH prefix, is it ok for this version as it is or do you want me to resend
with proper prefix?

Thanks for sharing...will have to look into it to avoid such mistakes.

It's okay for me, no need to resend. I just wanted to bring this to your
attention, so future patchsets can be improved.
