[PATCH 0/2] arm64: dts: qcom: Add Nothing Phone (4a) Pro support

[Oleksii Onchul]

Add initial device tree support for the Nothing Phone (4a) Pro
(FroggerPro), based on the Qualcomm Eliza platform.

The DTS describes the UART, GPIO keys and reserved memory,
including ramoops.

Boot-tested on the phone with Linux 7.3-rc3 using a minimal initramfs.
GPIO key events and ramoops persistence were verified. DTB and binding
checks pass.

LLM assistance was used to prepare and review the DTS and patch
descriptions. Hardware testing was performed by the author.
