ARM: dts: rockchip: add soc-specific uart compatibles for
From: Heiko Stuebner <heiko@...> Date: Thu, 19 Jan 2017 17:04:44 +0100
Commit-Message
The serial IPs in Rockchip socs are based on Designware uarts and thus bind against the snps,dw-apb-uart compatible. On all newer socs we also carry around per-soc compatibles that allow us to have more specific drivers in the future - if needed. The cortex-a9 socs rk3066 and rk3188 that were added first don't have those yet, so add them for completenes sake. Signed-off-by: Heiko Stuebner <heiko@...>
