     13description: |
     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.
     17
     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
     20  as very early serial console.
