[PATCH v2 0/3] arm64: dts: qcom: sm7125-samsung: add initial device tree for SM7125 Samsung platform

[Erikas Bitovtas <xerikasxx@gmail.com>]

Samsung Galaxy A52/A72 are smartphones released in 2021 on SM7125
(atoll) platform. This patch series introduces support for SM7125
Samsung devices with the following components enabled:
- Framebuffer
- GPIO keys
- Hall sensor
- Vibrator
- Regulators
- Reset input
- Real-time clock
- SD card
- UFS
- USB
Along with that, SM7125 was affected by a hang when launching SHM
bridge. A similar issue was reported on a similar chipset:
https://lore.kernel.org/all/20250721-sc7180-shm-hang-v1-1-99ad9ffeb5b4@trvn.ru/
Add SM7125 to the qcom_tzmem_blacklist to avoid hangs when booting.
