I need to reserve around 3 or 4 memory regions that are used by a single device driver.

I followed the guide from Xilinx. which works for a single memory region.

The Device tree looks like this:

reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
      reserved_m1: buffer1@60000000 {
      compatible = "shared-dma-pool";
      no-map;      
      reg = <0x0 0x60000000 0x0 0x00400000>;   
      };
      reserved_m2: buffer2@80000000 {
      compatible = "shared-dma-pool";
      no-map;      
      reg = <0x0 0x80000000 0x0 0x00100000>;   
      };
};
my_driver@0 {
  compatible = "dummy,my_driver";
  status = "okay";
  memory-region = <&reserved_m1>, <&reserved_m2>;
};

and my Probing function in the “my_driver”

static int my_driver_probe(struct platform_device *pdev)
{
  ...
  rc = of_reserved_mem_device_init(&pdev->dev);
  debug = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32));
  v_addr_m1 = dma_alloc_coherent(&pdev->dev, MY_MEM1_SIZE, &paddr, GFP_KERNEL); 
  printk("Allocated coherent memory Size: %d MB, vaddr: 0x%0llX paddr: 0x%0llXn", MY_MEM_SIZE / 1024 / 1024, (u64)v_addr, (u32)paddr);

  rc = of_reserved_mem_device_init_by_idx(&pdev->dev, np, 1);
  v_addr_m2 = dma_alloc_coherent(&pdev->dev, MY_MEM2_SIZE, &paddr_m2, GFP_KERNEL);
    
  printk("Allocated coherent memory Size: %d MB, vaddr: 0x%0llX paddr: 0x%0llXn", MY_MEM_SIZE / 1024 / 1024, (u64)v_addr, (u32)paddr);
  ...
  ...

With the above probing method I can only allocate for the first reserved-memory region.

How do I properly allocate for each regions?
