[PATCH v6 0/3] Add Xiaomi 12 Lite 5G (taoyao) device tree

[PATCH v6 0/3] Add Xiaomi 12 Lite 5G (taoyao) device tree

[Stanislav Zaikin]

This series adds device tree support for the Xiaomi 12 Lite 5G (taoyao),
based on the Qualcomm SM7325 SoC.

The display panel model is unknown, so bootloader-initialized
simple-framebuffer is therefore used to expose the display.

Changes in v6:
- Patch no. 1 - no changes
- Added a comment about reserved gpio ranges (patch no. 2)
- Removed "output-low" property from "hst_bt_en" node (patch no. 2)
- Moved common IPA properties for sm7325 devices to soc's dtsi (patch
  no. 3)
- Link to v5:
  https://lore.kernel.org/all/20260417084749.253242-1-zstaseg@gmail.com/

Changes in v5:
- Patch no. 1 - no changes
- Change vccq-supply to vccq2-supply in ufs node as it's ufs2.2 (patch no. 2)
- Val's patch for goodix-berlin didn't have effect on my touchscreen,
  therefore keep the touchscreen szie (no changes in this regard in
  patch no. 2)
- Link to v4:
  https://lore.kernel.org/all/20260305093941.305122-1-zstaseg@gmail.com/

Changes in v4:
- Patch no. 1 - no changes
- Removed Konrad's R-b tag, please take a look again (patch no. 2)
- Fixed vreg_s2b_0p7 regulator name to spmb2 (patch no. 2)
- Switched bluetooth to wcn6750-pmu (patch no. 2)
- Dropped qcom,local-bd-address-broken as it has no effect (patch no. 2)
- Added wifi calibration variant "Xiaomi_taoyao" (also sent board-2.bin
  files to ath11k) (patch no. 2)
- Link to v3:
  https://lore.kernel.org/all/20260224114424.1966947-1-zstaseg@gmail.com/

Changes in v3:
- Patch no. 1 - no changes
- Drop unit address for framebuffer node (patch no. 2)
- Add Konrad's R-b tag (patch no. 2)
- Link to v2:
  https://lore.kernel.org/all/20260216120715.3432191-1-zstaseg@gmail.com/

Changes in v2:
- Add Rob's A-b tag (patch no. 1)
- Add explicit framebuffer_reserved label (patch no. 2)
- Use memory-region for simple-framebuffer (patch no. 2)
- Fix reserved-memory naming: make node names consistent with labels
  and intended subsystem (CVP/camera/video) (patch no. 2)
- Convert mem-type value from <0x02> to <2> (patch no. 2)
- Fix s2b regulator comment style (patch no. 2)
- Remove unused gpio-reserved-ranges entry (<32 2>) (patch no. 2)
- Link to v1:

[PATCH v6 3/3] arm64: dts: qcom: sm7325: Move common IPA properties

[Stanislav Zaikin]

The qcom,gsi-loader and memory-region properties are common across
sm7325 devices. Move them from spacewar dts to the soc dtsi to avoid
duplication.

Re: [PATCH v6 2/3] arm64: dts: qcom: Add Xiaomi 12 Lite 5G (taoyao) DTS

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] The ramoops memory region is entirely consumed by `pmsg-size`, silently breaking kernel crash dumps.
- [Low] Device Tree unit address mismatch in the `rmtfs_mem` reserved memory node.

Author: Stanislav Zaikin <zstaseg@gmail.com>

arm64: dts: qcom: Add Xiaomi 12 Lite 5G (taoyao) DTS

This commit adds device tree support for the Xiaomi 12 Lite 5G handset,
enabling features such as display, touchscreen, UFS, power/volume buttons,
and remoteprocs.

Does this configuration leave any room for kernel crash dumps?

The node defines a memory region of exactly 2MB, but pmsg-size consumes the
entire 0x200000 bytes. Because pmsg-size consumes all available space, zero
space remains for record-size (which defaults to 0). Will the pstore/ramoops
driver be able to store kernel dmesg during panics or oops with this setup?

Is this unit address intentionally mismatched with the reg property?

The node is named rmtfs@ef500000, but its reg property specifies a base
address of 0xe7d00000. Can this structural syntax violation trigger a
simple_bus_reg dtc compiler warning?
