The following is supported: - Framebuffer - Volume Up, Down and Power Buttons - UFS Storage and SD Card - USB - Modem, ADSP and CDSP - Wi-Fi and Bluetooth - Cellular Data and SMS The reserved-memory layout deviates from sm6350.dtsi. The ADSP firmware shipped on this device requires a 64 MiB carveout, so the ADSP, camera, NPU, video and CDSP regions are redeclared at the addresses used by the vendor firmware. The bootloader also reserves additional memory (removed_region enlarged to 0x5e00000, plus the fastuh region); without these reservations the device hangs under memory pressure. qcom,msm-id and qcom,board-id are required for the Samsung bootloader to boot the kernel.
