A1 is an application processor designed for smart audio and IoT applications,
with Dual core ARM Cortex-A35 CPU. Unlike the previous GXL and G12 series,
there is no Cortex-M3 AO CPU in it.
This serial add basic support for the Amlogic A1 based Amlogic AD401 board:
which describe components as follows: Reserve Memory, CPU, GIC, IRQ,
Timer, UART. It's capable of booting up into the serial console.
The pclk for uart_AO_B need to be fixed once A1 clock driver is merged.
In this version, it rely on bootloader to enable the pclk gate
Changes since v3 at [2]:
- remove 0x in bus
Changes since v2 at [1]:
- add bus in dts according Martin's suggestion
- remove useless comment line
Changes since v1 at [0]:
- fix coding style
- collect Reviewed-by

it will be interesting to see which devices will use this SoC

Queued for v5.5,
Thanks for the new SoC support,
