The DTS uses hardware register values directly in pin controller pin configuration. These are not some IDs or other abstraction layer but raw numbers used in the registers. These numbers were previously put in the bindings header to avoid code duplication and to provide some context meaning (name), but they do not fit the purpose of bindings. It is also quite confusing to use constants prefixed with Exynos for other SoC, because there is actually nothing here in common, except the actual value. Store the constants in a header next to DTS and use them instead of bindings.
