Commit Message

Paul Elder Feb. 16, 2024, 9:54 a.m. UTC

  On the ISP that is integrated in the i.MX8MP, DMA addresses have been
extended to 34 bits, with the 32 MSBs stored in the DMA address
registers and the 2 LSBs set to 0.

To support this:
- Shift the addresses to the right by 2 when writing to registers
- Set the dma mask to 34 bits
- Use dma_addr_t instead of u32 when storing the addresses

The signature for dma_set_mask_and_coherent() uses u64 for the mask, so I 
would use the same type here as well.

On a side note, any chance your mail client would have an option to
avoid this kind of wrapping ? :-)
