This patch adds Tesla FSD SoC specific data to enable pinctrl.
FSD SoC has similar pinctrl controller as found in the most
samsung/exynos SoCs.

No wake-up interrupts (eint_wkup_init)? It's fine not to have them but
just looks incomplete.

In general looks ok, except discussion about compatibles.

Looks good to me once Krysztof is happy with this I expect to get the
pin control portions from him by a pull request.
