[PATCH v2 0/5] Support TQMa8QM

From: Alexander Stein

Date: Wed Feb 11 2026 - 07:40:15 EST


Hi,

this series adds support for TQ's TQMa8QM. The first 2 patches are prepatory:
1. Add support for USB devices in cdns USB3 host controller, namely
onboard-devices as USB hubs. Implemented similarily to snps,dwc3-common.yaml.

2. 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.

3 & 4. Device bindings and platform DT

5. 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.

Changes in v2:
The need for clock-output-names properties for renesas,9fgv0441 has
been removed by reworkging the PCIe clocking

Best regards,
Alexander
