[PATCH v3 0/1] cpufreq: ti: Fix probe ordering with k3-socinfo

Posted by Akashdeep Kaur 1 week, 5 days ago

For K3 SoCs, ti-cpufreq depends on k3-socinfo to provide SoC revision
information via soc_device_match(). If ti-cpufreq probes before
k3-socinfo, soc_device_match() returns NULL, causing incorrect 
revision detection and OPP table initialization failures.

Add EPROBE_DEFER handling in ti-cpufreq when soc_device_match() fails
for K3 SoCs, ensuring k3-socinfo probes first.

Changes in v3
- Simplified to single patch (EPROBE_DEFER only)
- Changed the logic to detect whether the probe is for am62 family SoCs
- Dropped device link patch after analysis as revision information is 
  cached after successful probe. Module reload also works as k3-socinfo 
  stays bound during normal operation
- Link to v2: https://lore.kernel.org/all/20260401105404.1194717-1-a-kaur@ti.com/

Changes in v2
- Added DT bindings documentation for ti,soc-info property
- Reordered patches: bindings first, then driver changes, then DTS
- Link to v1: https://lore.kernel.org/all/20260330120105.2985200-1-a-kaur@ti.com/

Testing
- Verified correct probe ordering on AM625, AM62A7, AM62P5 platforms
