The Special Function Registers on all Exynos SoC, including ARM64, are 32-bit wide, so entire driver uses matching functions like readl() or writel(). On 64-bit ARM using unsigned long for register masks: 1. makes little sense as immediately after bitwise operation it will be cast to 32-bit value when calling writel(), 2. is actually error-prone because it might promote other operands to 64-bit.

The "invalid function %d on pin %d .\n" message is triplicated in the driver in different variants, just pull it into the function and have it once in the driver. The bonus is that all variants of the message now print the pin number and AF consistently, so it is easier to debug such pinmux problems. Signed-off-by:

The Rockchip GPIO and pin control modules are only present on Rockchip SoCs. Hence add a dependency on ARCH_ROCKCHIP, to prevent asking the user about this driver when configuring a kernel without Rockchip platform support. Note that before, the PINCTRL_ROCKCHIP symbol was not visible, and automatically selected when needed. By making it tristate and user-selectable, it became visible for everyone.
