This patch continues support for the imxrt series now adding the imxrt1170

This patch contains:
- Update to imxrt_defconfig
- Devicetree
- Clock driver
- Pinctrl driver
- New pll

This patch also updates some documentation for both imxrt1170 an 1050.

The i.MXRT1170 has a vast array of features including two cores,
2 Ethernet, 2 USB phy, and a 2d gpu.

It also is featured in a new google coral board

No it does not, I already merged that.

I think you should probably split up your series per-subsystem so the
clock bindings and changes can be merged separately etc.

Then the DTS files can be added to the ARM SoC tree as a final step.

When you send everything in one bundle like this subsystem maintainers
don't know if they can merge e.g. just the clock patches separately
and be done with their part (like what I did with pinctrl).

Yours.

Do you think its possible to add Docs for Device tree compatibles that 
aren't added yet?

Thanks,

Bindings and drivers are orthogonal, we only submit them together
to provide context for reviewers.

It is also possible to submit device trees with compatibles and entire
nodes without bindings because there essentially is no real police for
this. Of course it is not recommended.

If you are confident that bindings and device trees will come in the
same merge window it is fine to merge them separately through different
trees.
