[PATCH v4 0/1] cpufreq: ti: Fix probe ordering with k3-socinfo

From: Akashdeep Kaur

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 a needs_k3_socinfo flag to ti_cpufreq_soc_data to properly handle
probe deferral when k3-socinfo hasn't registered the SoC device yet.
This follows the existing multi_regulator pattern in the driver.

Changes in v4
- Use needs_k3_socinfo flag in soc_data
- Link to v3: https://lore.kernel.org/all/20260527062534.1808422-1-a-kaur@xxxxxx/

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@xxxxxx/

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@xxxxxx/

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