8 title: Amlogic Meson SoC UART Serial Interface
11   - Neil Armstrong <neil.armstrong@linaro.org>
14   The Amlogic Meson SoC UART Serial Interface is present on a large range
15   of SoCs, and can be present either in the "Always-On" power domain or the
16   "Everything-Else" power domain.
18   The particularity of the "Always-On" Serial Interface is that the hardware
19   is active since power-on and does not need any clock gating and is usable
