It's missing the reg-io-width property. My initial idea was to add a completely new entry, so new exynos platforms that don't exhibit the same issue could grow the enum there. Although now that I think about it, I could grow the gs101 enum and set the reg-io-width property for gs101 after that list. Best regards, Ivo. > Best regards, > Krzysztof >

Add dedicated samsung,exynos8895-uart compatible to the dt-schema for representing uart of the Exynos8895 SoC. Like GS101, it has a required DT property samsung,uart-fifosize, but it does not exhibit the 32 bit register access limit.
