[PATCH v3 0/2] Add EPSS L3 provider support on Qualcomm Shikra SoC

Posted by Raviteja Laggyshetty 4 days, 19 hours ago

Add Epoch Subsystem (EPSS) L3 scaling support on Qualcomm Shikra SoC.
EPSS hardware on Shikra is similar to other SoCs but supports only twelve
L3 frequency entries (LUT). Reading the LUT beyond supported frequencies
can expose incorrect frequencies.
Introduce new compatible to represent this constrained variant of EPSS.

Changes in v3:
- Update the commit text to reflect the correct binding yaml.
- Link to v2: https://patch.msgid.link/20260603-shikra_epss_l3-v2-1-480cdb5abc85@oss.qualcomm.com

Changes in v2:
- Use the existing qcom,osm-l3 bindings to describe the Qualcomm Shikra
  EPSS L3 hardware, as it is similar to other Qualcomm EPSS/OSM L3
  hardware. [Krzysztof]
