Subject: [PATCH 0/3] iommu/arm-smmu: introduction of ACTLR implementation for Qualcomm SoCs

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.
