[PATCH v2 0/9] 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:

http://openlinux.amlogic.com:8000/download/

Notes:
* The patchset requires https://lkml.org/lkml/2014/7/7/344
* Patch [3/9] is already in tty-next branch

Changes since v1:
* clocksource driver: deleted useless pointers to timers not used and code
  restyling
* machine file: deleted useless compatibles and .init_machine
* DTS: addressed several issues
* defconfigs: deleted meson_defconfig
* documentation: split documentation patch and added bindings documentation

Carlo Caione (9):
  ARM: meson: debug: add debug UART for earlyprintk support
  ARM: meson: documentation: add UART documentation
  ARM: meson: serial: add MesonX SoC on-chip uart driver

  ARM: meson6: clocksource: add Meson6 timer support
  ARM: meson: documentation: add bindings documentation
  ARM: meson: add basic support for MesonX SoCs
  ARM: meson: dts: add basic Meson/Meson6/Meson6-atv1200 DTSI/DTS
  ARM: meson: update multi_v7_defconfig
