From 1dd5581354547641ef6e19e6a90727a985b1be87 Mon Sep 17 00:00:00 2001 From: David Lechner Date: Fri, 6 Jan 2017 11:07:01 -0800 Subject: ARM: dts: keystone: Add "ti,da830-uart" compatible string The TI Keystone SoCs have extra UART registers beyond the standard 8250 registers, so we need a new compatible string to indicate this. Also, at least one of these registers uses the full 32 bits, so we need to specify reg-io-width in addition to reg-shift. "ns16550a" is left in the compatible specification since it does work as long as the bootloader configures the SoC UART power management registers.
