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.
NAK!! We can't break the booting boards with existing boot loaders. I suggest you to first get the driver updated to take care of the UART PM register and then enable the support for it. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
