Subject: [PATCH v4 0/3] Add DMA driver for StarFive JH7110 SoC

This patch series adds dma support for the StarFive JH7110 RISC-V
SoC. The first patch adds device tree binding. The second patch includes
dma driver. The last patch adds device node of dma to JH7110 dts.

The series has been tested on the VisionFive 2 board which equip with
JH7110 SoC and works normally.

The last patch should be applied after the following patchset:
https://lore.kernel.org/all/20230221083323.302471-1-xingyu.wu@starfivetech.com/

Changes since v3:
- Constrain the minItems of resets to 2 for jh7110 dma in the
  dt-binding.
- Replaced all uses of of_device_is_compatible with of_device_get_match_data.
- Moved the definition of struct axi_dma_chip_config to dw-axi-dmac-platform.c

v3: https://lore.kernel.org/all/20230227131042.16125-1-walker.chen@starfivetech.com/

Changes since v2:
- Added minItems with value 1 and changed the maxItems' value to 2 about
  resets properties in the dt-binding.
- Added match data for jh7110-axi-dma and executed reset call to match
  data.
- Dropped reset-names from dma node of device tree.

v2: https://lore.kernel.org/all/20230221140424.719-1-walker.chen@starfivetech.com/

Changes since v1:
- Rebased on Linux 6.2.
- Changed the compatible string to SoC specific and dropped '-rst' from
  reset-names in the dt-binding.
- Dropped 'snps,num-hs-if' in the dt-binding.
- Use different configuration on CH_CFG registers according to the compatible string.

v1: https://lore.kernel.org/all/20230206113811.23133-1-walker.chen@starfivetech.com/
