[PATCH 2/2] arm64: dts: qcom: sm7325: Add Samsung Galaxy M52 5G

[Asdlerto Korry via B4 Relay <devnull+korryasdlerto.gmail.com@kernel.org>]

From: Asdlerto Korry <korryasdlerto@gmail.com>

Add the device tree for the Samsung Galaxy M52 5G (samsung,m52xq)
smartphone, which is based on the SM7325 SoC.

Supported features are, as of now:
* UFS
* USB (peripheral)
* microSD card slot
* Display via simple-framebuffer
* Power & volume buttons
* Remoteprocs (ADSP, MPSS, WPSS)
* WiFi & Bluetooth (WCN6750)
* IPA
* Venus video decoding/encoding
* NFC (Samsung S3FWRN5)
* Vibrator
* GPU (with zap shader)
* PMK8350 ADC thermistor, ramoops
* Regulators, i2c, uart, gpi dma
