Subject: [PATCH v3 2/7] pinctrl: samsung: Add Exynos850 SoC specific data
Add Samsung Exynos850 SoC specific data to enable pinctrl support for
all platforms based on Exynos850.
Signed-off-by: Sam Protsenko <semen.protsenko@...aro.org>
---
Changes in v3:
- Added const qualifier to exynos850_bank_type_* structs
- Added const and __initconst qualifiers to exynos850_pin_banks*[]
arrays
- Renamed EXYNOS9_* mactos to EXYNOS850_*
Changes in v2:
- Removed .suspend/.resume callbacks, as retention registers are not
implemented yet for Exynos850
- Removed .eint_gpio_init for AUD domain, as there are no external
interrupts available for that domain
