[PATCH v3 0/2] Add initial support for Lenovo YOGA Tablet 10 (Wi-Fi)

[Akari Tsuyukusa]

This series of patches adds basic support to
Lenovo YOGA Tablet 10 (Wi-Fi).

Like v2, schema validation still reports errors in mt6589.dtsi,
but this series does not aim to fix those pre-existing issues.

Changes in v3:
- Add "Acked-by" to dt-binding
- Remove "mt6589-lenovo-blade.dtsi"
- Drop UART node

[PATCH v3 1/2] dt-bindings: arm: mediatek: Add Lenovo YOGA Tablet 10 (Wi-Fi)

[Akari Tsuyukusa]

Add an entry for Lenovo YOGA Tablet 10 (Wi-Fi) tablet board,
named b8000-f.

It belongs to Lenovo's "blade" product family, a codename found in the
stock Android "ro.product.board" property (e.g., "blade10_row_wifi" for
B8000-F and "blade8_row_3gdata" for B6000-H).

The "blade" family includes several variants with different screen sizes
and connectivity:

YOGA Tablet 8 (8-inch display)
B6000-F  : Wi-Fi
B6000-H  : Wi-Fi + 3G (Data only)
B6000-HV : Wi-Fi + 3G (Voice)

YOGA Tablet 10 (10-inch display)
B8000-F  : Wi-Fi
B8000-H  : Wi-Fi + 3G (Data only)

These devices feature 1GB of RAM and powered by MediaTek MT8125 or MT8389
SoC. Since these SoCs are tablet-oriented variants of MT6589,
they are grouped under the "mediatek,mt6589" compatible string.

No changes from v2, so added Acked-by received in v2.

[PATCH v3 2/2] arm: dts: mediatek: mt6589: add basic support for Lenovo B8000-F

[Akari Tsuyukusa]

Lenovo YOGA Tablet 10 (Wi-Fi) - B8000-F is a tablet from the "blade"
product family. It is powered by MediaTek MT8125 SoC, (a tablet variant
of MT6589), and features 1GB of RAM.

The "blade" family consists of several variants based on screen size
and connectivity:
- YOGA Tablet 8 (8"): B6000-F (Wi-Fi), B6000-H/HV (3G)
- YOGA Tablet 10 (10"): B8000-F (Wi-Fi), B8000-H (3G)

This patch adds basic support, including a simple-framebuffer that
uses the panel already initialized by the bootloader.

While many parts of this Device Tree are expected to be common across
other "blade" family boards, they are kept within the B8000-F specific
file for now as it is the only supported device.

Changes in v3
- Drop UART node
  It was probably correct, but I'm not sure and haven't tested it
  so I removed it.
- Remove "mt6589-lenovo-blade.dtsi"
  There are currently no plans to add support for variants other
  than b8000-f, and the Device Tree is also small and there is no point
  in dividing it, so I deleted it and merged it
  into "mt6589-lenovo-b8000-f.dts"
