Msm8953 For Arm64 Driver High Quality Repack Instant

Title: Technical Overview and Driver Architecture for the MSM8953 Platform on ARM64

DMA coherency hints

// For non-cache-coherent buses (common on MSM8953)
dma_map_single(dev, buf, len, DMA_TO_DEVICE);
dma_sync_single_for_device(dev, dma_handle, len, DMA_TO_DEVICE);
ALSA SoC (ASoC): Managing the WCD9335 audio codec for low-latency playback.
Security and firmware validation
What is an ARM64 Driver?
Audio: Uses an updated codec (cajon-v2) similar to the MSM8916. High-quality audio support requires specific ALSA UCM configuration files for each device.
