[PATCH v4 0/2] Support TQMa8QM

From: Alexander Stein

Date: Thu Mar 26 2026 - 09:03:37 EST


Hi,

this series adds support for TQ's TQMa8QM. In v4 several prepatory have been
merged already. So this series include only the two missing patches:
1. platform DT

2. 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 v4:
* Reduced recipient audience due to reduced patches
* Sorted nodes by name (not by phandle)

Changes in v3:
* Small cleanups in patch 1 & 4

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

Best regards,
Alexander
