[PATCH linux dev-5.4 00/16] Aspeed: Add XDMA and SCU interrupt controller drivers

This series adds an interrupt controller driver, which has been accepted
upstream, for the AST2500/AST2600 SCU. It then adds the XDMA driver, which has
been reviewed upstream and is pending merge.
The final four patches are not meant to be upstreamed in their current state,
but they do get the driver to function on the AST2600 A1 chip.
