[PATCH v4 0/2] arm64: dts: qcom: Add support for the Xiaomi 17 Ultra series of devices

[Igor Belwon]

Hi,

This series adds support for the Xiaomi 17 Ultra series of devices,
consisting of the Chinese domestic region version of the device as well
as the EEA version. The only real difference in the devices is the 
battery capacity.

Currently only basic devicetree support is added, with driver support
for the display panel as well as other hardware blocks to be added in
future patch series.

2.56.0

[PATCH v4 2/2] arm64: dts: qcom: Add support for Xiaomi 17 Ultra phones

[Igor Belwon]

The Xiaomi 17 Ultra device, codenamed 'nezha', is a flagship mobile
phone released by Xiaomi in 2025 (China)/2026 (EEA). It uses the
Qualcomm Kaanapali SoC.

This device's configuration is based on the 'MTP' from Qualcomm,
as is also referenced in the downstream sources. Apart from the
usual differences (i.e. codecs, panel), it also uses the newer
WCN7860 (peach) connectivity chip, which is why WiFi/BT are not
brought up.

The difference between the EEA and the Chinese model is the battery
capacity, notably, the EEA model has a smaller 6000 mAh battery when
compared to the CN 6800 mAh SiC battery.

Currently implemented features are:
 - Booting
 - Power and volume keys
 - Storage (UFS)
 - USB-C Peripheral and Host modes
 - GPU
 - Fuel gauge
 - ADSP, CDSP, SoCCP remote processors
