Add the "lenovo,blade" compatible string for the Lenovo YOGA Tablet 8/10
family and add compatible strings for each board
(B6000-F, B6000-H, B8000-F, B8000-H).

These tablets are based on the "blade" platform, featuring 1GB of RAM
and powered by MediaTek MT8125 or MT8389 SoCs. Since these SoCs are
tablet-oriented variants of the MT6589, they are grouped under the
"mediatek,mt6589" compatible string.

You're adding support (a devicetree) only for the B8000-F though...

Did you really test this with dtbs_check?

...also, is the "lenovo,blade" really used for anything (bootloader)?

You can either fix that or just remove the lenovo,blade compatible... but please,
test with `make dtbs_check` before sending a v2 :-)

Cheers,
Angelo

I think I did it, but I may have missed warnings or errors.
(I was sleepy so I don't remember much, lack of sleep is very bad...)
I must check dtbs_check before sending v2.

There is no user of it, I'll remove in v2.

Thank you for the guidance.
Best regards,
Akari

I don't see users of few of these. Also, explain in commit msg
differences between 'f' and 'h'.

Best regards,

I don't see the "blade" used either.

Hi Kozlowski, thank you for your review.

I will remove the unused compatible strings (b6000-f, b6000-h, b8000-h
and blade) in v2. I will also add an explanation to the commit message
that '-f' stands for Wi-Fi-only models and '-h' stands for 3G models.

Note, "blade" can be found in "ro.product.board" (build.prop).
B8000-F: blade10_row_wifi
B6000-H: blade8_row_3gdata

Best regards,
Akari
