[PATCH v3 0/2] Add support for HwaCom AmazeTV

[Carlo Caione]

From: Carlo Caione <carlo@endlessm.com>

New DTS to support the HwaCom AmazeTV based on the Meson S905X SoC.

Changelog:
 v2:
  - Changed DTS name to meson-gxl-s905x-hwacom-amazetv.dts
 v3:
  - Split patchset in two parts: DTS and documentation update
  - Makefile now sorted alphabetically
  - DTS nodes now sorted alphabetically

[PATCH v3 2/2] ARM64: dts: meson-gxl: Add support for HwaCom AmazeTV

[Carlo Caione]

From: Carlo Caione <carlo@endlessm.com>

This patch adds support for the HwaCom AmazeTV set-top-box. The
hardware configuration is really similar to the other GXL boards but
for this hardware we need to limit the max-frequency of the eMMC to
have it working.
