[PATCH v1 0/2] arm64: dts: qcom: Add Xiaomi Poco M3 (citrus)

[Amir Hanip]

This series adds initial support for the Xiaomi Poco M3 (codename
citrus), a smartphone based on the Qualcomm Snapdragon 662 (SM6115).

Currently working:
- UFS and microSD
- USB host (OTG), limited to high-speed (SuperSpeed is untested)
- WiFi
- Bluetooth
- Remoteprocs (ADSP, CDSP and modem)

The memory map for the ADSP, CDSP, IPA and GPU regions differs from
the SM6115 defaults and follows the layout of the stock firmware.

Not included yet: the display panel, touchscreen and the GPU display
pipeline, which depend on drivers that are not upstream. Until then
the display is only available through simple-framebuffer. Audio is
not included either.

Firmware and userspace: WiFi, Bluetooth and the remoteprocs need
device-specific firmware which is not part of this series. WiFi
additionally needs qrtr, tqftpserv and rmtfs running in userspace,
and the Bluetooth controller needs its BD address set from userspace.

Tested on a Poco M3 booted from microSD with a v7.2-based kernel.
The series is based on qcom/for-next and passes W=1 and
CHECK_DTBS=y for qcom/sm6115-xiaomi-citrus.dtb.

[PATCH v1 2/2] arm64: dts: qcom: Add Xiaomi Poco M3

[Amir Hanip]

Add initial device tree for the Xiaomi Poco M3 (codename citrus),
based on the Qualcomm Snapdragon 662 (SM6115) SoC.

Currently working:
- UFS and microSD
- USB host (OTG)
- WiFi
- Bluetooth
- Remoteprocs (ADSP, CDSP and modem)

WiFi, Bluetooth and the remoteprocs need device-specific firmware,
which is not part of this series. WiFi additionally needs qrtr,
tqftpserv and rmtfs running in userspace, and the Bluetooth
controller needs its BD address set from userspace.

Display panel, touchscreen, and the GPU display pipeline will
be added later, so the display is currently only available through
simple-framebuffer.
