Subject[PATCH v2 0/3] iommu/arm-smmu: introduction of ACTLR implementation for Qualcomm SoCs
Date
This patch series consists of three parts and covers the following:

1. Introducing intital set of driver changes to implement ACTLR register
for custom prefetcher settings in Qualcomm SoCs.

2. Adding ACTLR data and implementation operations for SM8550.

3. Re-enabling context caching for Qualcomm SoCs to retain prefetcher
settings during reset and runtime suspend.

Changes in v2 from v1:
- Incorporated suggestions on v1 from Dmitry,Konrad,Pratyush.
- Added defines for ACTLR values.
- Linked sm8550 implementation structure to corresponding
compatible string.
- Repackaged actlr value set implementation to separate function.
- Fixed indentation errors.
- Link to v1: https://lore.kernel.org/all/20231103215124.1095-1-quic_bibekkum@quicinc.com/

Changes in v1 from RFC:
- Incorporated suggestion form Robin on RFC.
- Moved the actlr data table into driver, instead of maintaining
it inside soc specific DT and piggybacking on exisiting iommus
property (iommu = <SID, MASK, ACTLR>) to set this value during
smmu probe.
- Link to RFC: //lore.kernel.org/all/a01e7e60-6ead-4a9e-ba90-22a8a6bbd03f@quicinc.com/
