[PATCH 0/7] ARM: meson: add preliminary support for MesonX/Meson6 SoCs

[Carlo Caione]

Amlogic AML8726-MX (codename Meson6) is a highly integrated multimedia
application processor SoC for Multimedia Internet Device (MID), tablet
and Set Top Box (STB). It integrates a powerful CPU, a 2D/3D graphics
subsystem and a state-of-the-art video decoding engine together with
all major peripherals. It is manufactured by Amlogic, inc.

This patchset introduces preliminary support for Meson6-based SoCs but
several IPs and drivers are common among all the MesonX SoCs.

Amlogic doesn't release any documentation about their SoCs, so the code
has been reverse-engineered from the messy source code released at:

Carlo Caione (7):
  ARM: meson: debug: add debug UART for earlyprintk support
  ARM: meson: serial: add MesonX SoC on-chip uart driver
  ARM: meson6: clocksource: add Meson6 timer support
  ARM: meson: add basic support for MesonX SoCs
  ARM: meson: dts: add basic Meson/Meson6/Meson6-atv1200 DTSI/DTS
  ARM: meson: update defconfigs
  ARM: meson: update documentation (uart, timer and vendors)
