The MSM8953 uses Qualcomm's Mobile Display Processor (MDP5) or Display Processing Unit (DPU). msm8953 for arm64 driver
MSM8953 uses either eMMC 5.1 or SDIO for storage. The driver is sdhci-msm.c .
Unlike older 32-bit platforms restricted by the 4GB physical addressing limit, ARM64 handles a massive physical address space. However, the MSM8953 hardware registers remain mapped within the lower 32-bit address space (MMIO regions) for backward compatibility.
