This patch series add driver support for StarFive JH8100 SoC crypto
engine. Patch 1 adds compatible string and update irq descriptions for
JH8100 device. Subsequent patches update current driver implementations
to support both 7110 and 8100 variants.
v2->v3:
- Use of device data instead of #ifdef CONFIG_ for different device
variants.
- Updated dt bindings compatible and interrupts descriptions.
- Added patch 4 to support hardware quirks for dw-axi-dmac driver.
v1->v2:
- Resolved build warnings reported by kernel test robot
https://lore.kernel.org/oe-kbuild-all/[email protected]/
Jia Jie Ho (6):

2.34.1
Adds separate dma hardware descriptor setup for JH8100 hardware quirks.
JH8100 engine uses AXI1 master for data transfer but current dma driver
is hardcoded to use AXI0 only. The FIFO offset needs to be incremented due
to hardware limitations.
