[PATCH 0/2] Introduce support for Xiaomi Mi 8

[PATCH 0/2] Introduce support for Xiaomi Mi 8

[David Heidelberg via B4 Relay]

Currently only Mi 8 itself is supported, but the
sdm845-xiaomi-dipper-common should ensure, that other family members
such as Mi 8 Pro, Mi 8 Explorer will be likely supported too without
much of additional work. These variants should differ only in the small
details (such as battery size, fingerprint sensor etc.).

Minimal viable support for xiaomi-dipper. Enough to get basic u-boot and
Linux functional. More improvements will follow.

The display and touchscreen support are work-in-progress, but waiting
for other bits to land.

[PATCH 2/2] arm64: dts: qcom: add Xiaomi Mi 8 (dipper)

[David Heidelberg via B4 Relay]

From: David Heidelberg <david@ixit.cz>

Initial submission for one member of the prime Xiaomi Mi 8 family.
Mi 8 Pro (equuleus) and Mi 8 Explorer (ursa) are nearly identical.
Known differences are battery capacity and fingerprint sensor placement.
This submission includes basic abstraction for other developers to be
able easily extend it to support other variants.

What does work: framebuffer, USB, UFS, Bluetooth, Wi-Fi.

Based on work of multiple people trying to bring the device in the past.
Last attempt was done by Max Furman.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The compatible string `xiaomi,dipper` is added to two mutually exclusive schema blocks with conflicting constraints, allowing incomplete compatible lists to silently pass validation.

dt-bindings: arm: qcom: Add Xiaomi Mi 8 family compatibles

This commit adds device tree binding compatibles for the Xiaomi Mi 8 smartphone
family, codenamed dipper, and documents variants such as ursa and equuleus.

[Severity: Medium]
Was xiaomi,dipper mistakenly added to this 2-element block as well?

Since xiaomi,dipper is already defined in the 3-element Xiaomi Mi 8 family
block above, adding it here introduces a regression in schema validation.
A device tree using an incomplete compatible array like 
["xiaomi,dipper", "qcom,sdm845"] will pass schema validation by matching this
block, completely bypassing the requirement for the "xiaomi,dipper-common"
fallback string.

Would removing it from this generic list ensure the intermediate fallback is
properly enforced for the dipper board?

Yeah, forgot to remove simplified entry.
Will be addressed in the v2.
