      ASoC: sprd: Add reserved DMA memory support · 1587a061
      Baolin Wang authored
      For Spreadtrum audio platform driver, it need allocate a larger DMA buffer
      dynamically to copy audio data between userspace and kernel space, but that
      will increase the risk of memory allocation failure especially the system
      is under heavy load situation.
      
      To make sure the audio can work in this scenario, we usually reserve one
      region of memory to be used as a shared pool of DMA buffers for the
      platform component. So add of_reserved_mem_device_init_by_idx() function
      to initialize the shared pool of DMA buffers to be used by the platform
      component.
