Hi,

this series adds support for TQ's TQMa8QM. The first 3 patches are prepatory:
1. Add support for clock-output-names for clk-renesas-pcie. This is necessary
as clk-imx8qxp-lpcg.c (driver for phyx1 phyx2 clock gating) reqiures that
property on the parent clock.

2. Add support for USB devices in cdns USB3 host controller, namely
onboard-devices as USB hubs. Implemented similarily to snps,dwc3-common.yaml.

3. Add DMA IRQ for PCIe controller. Similar to commit 0b4c46f9ad79c
("arm64: dts: imx8qm-ss-hsio: Wire up DMA IRQ for PCIe") which was only tested
on imx8qxp which just has one PCIe controller.

4 & 5. Device bindings and platform DT

6. Workaround for missing "ERR050104: Arm/A53: Cache coherency issue"
workaround. See [1] for details. Split into separate commit for easy revert
once an errata workaround has been integrated.

Best regards,
Alexander
