[PATCH v2 0/7] Initial Redmi Note 8T support and more

[Barnabás Czémán]

Redmi Note 8 and 8T are sibling devices the only difference
is Redmi Note 8T have NFC.
This patch series is commonizing Redmi Note 8 devicetree
for a base for both devices.

The patch series also contains some fixes for Redmi Note 8:
- Fix reserved memory ranges, they were wrongly defined.
- Remove board-id, board-id is not neccessary for the bootloader.
- Fix reserved-gpio-ranges the reserved ranges was wrongly
defined what caused the device crash on the boot.
- Remove unnecessary usb-extcon, gpio102 is related to DisplayPort
what is not supported by these devices.
- Use memory-region property for framebuffer.

Depends on:

Changes in v2:
- Fix copyright in sm6125-xiaomi-ginkgo.dts as requested.
- Use memory-region property for the framebuffer.
- Add comment about the NFC.
- Remove msm-id change in favor of [1].
- Link to v1: https://lore.kernel.org/r/20260112-xiaomi-willow-v1-0-8e4476897638@mainlining.org

[PATCH v2 2/7] arm64: dts: qcom: sm6125-xiaomi-ginkgo: Correct reserved memory ranges

[Barnabás Czémán]

The device was crashing on high memory load because the reserved memory
ranges was wrongly defined. Correct the ranges for avoid the crashes.
Change the ramoops memory range to match with the values from the recovery
to be able to get the results from the device.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Deps: looking for dependencies matching 1 patch-ids
 Deps: Applying prerequisite patch: [PATCH RFT] arm64: dts: qcom: sm6125-ginkgo: Fix missing msm-id subtype
 Base: f417b7ffcbef7d76b0d8860518f50dae0e7e5eda (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Warnings in base: 266

Have you verified this new and improved(tm) map e.g. by booting up
the kernel with memtest=1 in cmdline?
