Subject: [PATCH v3 0/4] dmaengine: sun6i: Allwinner D1 support

D1 is a new RISC-V SoC that uses mostly the same peripherals as
existing ARM-based sunxi SoCs. This series adds dmaengine support for
D1, after fixing an issue where the driver depended on architecture-
specific behavior (patch 2) and resolving a TODO item (patch 3).

Changes in v3:
 - Fix format warnings
 - Fix shift warnings for 32-bit dma_addr_t and 32-bit phys_addr_t
 - Make explicit that v_lli->src/dst only hold the low 32 bits

Changes in v2:
 - Fix `checkpatch.pl --strict` style issues (missing spaces)

Samuel Holland (4):
  dt-bindings: dma: sun50i-a64: Add compatible for D1
  dmaengine: sun6i: Do not use virt_to_phys
  dmaengine: sun6i: Add support for 34-bit physical addresses
  dmaengine: sun6i: Add support for the D1 variant
