[PATCH v2 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).

Changes in v2:
- removed lenovo,b6000-f, lenovo,b6000-h, lenovo,b8000-h, lenovo,blade
  compatible strings
- remove "0x" prefix from memory Device Tree node
- remove "compatible" property from mt6589-lenovo-blade.dtsi
- dt-bindings commit message explains this product family in detail

Note:
$ make CHECK_DTBS=y mediatek/mt6589-lenovo-b8000-f.dtb
says that

These warnings originate from existing mt6589.dtsi definitions and are
not introduced by this patch series.

[PATCH v2 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.

[PATCH v2 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 which belongs
to the "blade" product family. It is powered by MT8125 SoC,
which is the tablet version of MediaTek MT6589, and has 1GB RAM.

Like other devices in the "blade" family, it uses a framebuffer
initialized by the bootloader at a consistent memory address and size.
This patch adds basic support including UART and simple-framebuffer.

Hi,

Please ignore this patch for now.

I found that the panel on the Lenovo YOGA Tablet 8 is 800x1200,
which is incompatible with the current simple-framebuffer configuration.

I will fix the Device Tree in v3.

Best regards,
Akari Tsuyukusa
