Here is what I suggest. Now that it's obvious there is some common platform for moder Exynos SoCs, and it's probably Exynos9, I'd suggest next course of action (if maintainers agree): 1. Remove this one 2. Rename exynos850_bank_type_off to exynos9_bank_type_off 3.

What is 'types'? Moreover, it doesn't look very different from EXYNOS850_PIN_BANK_EINTN() -- just because I created EXYNOS850_PIN_BANK_EINTN() exactly from this downstream macro. I was strictly prohibited adding EXYNOS9_* stuff back at the time. But now I guess it should be apparent we are actually dealing with Exynos9 common platform.

Please add filter fields to EXYNOS850_PIN_BANK_EINTG() instead of adding pretty much the same macro (it is the same, I created EXYNOS850_PIN_BANK_EINTG() from exactly this macro).

But why not also rename exynos850_* to exynos9_*? I've a feeling that a lot of modern Exynos SoCs have the same pin bank configuration. Wouldn't it be better to use exynos9_ prefix for all such SoCs than exynos850_*?
