[PATCH v2 0/3] iommu/arm-smmu: introduction of ACTLR implementation for Qualcomm SoCs

[Bibek Kumar Patro]

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@xxxxxxxxxxx/

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@xxxxxxxxxxx/
