Adds basic support for the Tesla Full Self-Driving (FSD) SoC. This
SoC contains three clusters of four Cortex-A72 CPUs, as well as
several IPs.

Patches 1 to 9 provide support for the clock controller (which is
designed similarly to Exynos SoCs).

The remaining changes provide pinmux support, initial device tree support.

- Changes since v4
* fixed 'make dtbs_check' warnings on patch 14/16

- Changes since v3
* Addressed Stefen's review comments on patch 14/16
* Fixed kernel test robot warning on patch 04/16
* rebsaed this series on Krzysztof's pinmux new binding schema work
[1]

- Changes since v2
* Addressed Krzysztof's and Stephen's review comments
* Added Reviewed-by and Acked-by tags
* Rebased on next-20220120

- Changes since v1
* fixed make dt_binding_check error as pointed by Rob
* Addressed Krzysztof's and Rob's review comments
* Added Reviewed-by and Acked-by tags
* Dropped SPI, MCT and ADC from this series (to be posted in small
sets)

NOTE: These patches are based on Krzysztof's pinmux for-next branch
commit 832ae134ccc1 ("pinctrl: samsung: add support for Exynos850 and
ExynosAutov9 wake-ups") [1]
https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/samsung.git/l
og/?h=for-next

Thanks, applied DTS/soc and pinctrl patches.

I expect Sylwester will pick up the clock ones. Otherwise please let
me know to pick it up as well.

I forgot that clock macros are used in DTS. This does not compile and I cannot
take drivers into DTS branch.

Alim,
DTS changes dropped. Please resend with the same trick we did for
Exynos850 board - hard-coded clock IDs as defines. See:

https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git/diff/arch/arm6
4/boot/dts/exynos/exynos850.dtsi?h=samsung-dt64-5.17-
2&id=e3493220fd3e474abcdcefbe14fb60485097ce06

Ok, I will resend patch 14 and 15 (DTS changes) only as suggested above.

Best regards,
Krzysztof
