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 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/
