This chip has a dma controller integrated. Up to now the maximal burst size was hard-coded to 0x10. But it turns out that Raspberry Pi 4 does only work with the smaller maximal burst size of 0x8. This series adds a new optional property to the driver, dma-burst-sz. The very same property is already used by another drivers in the kernel.
