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 Signed-off-by: Akashdeep Kaur --- Akashdeep Kaur (1): cpufreq: ti: Add EPROBE_DEFER for K3 SoCs drivers/cpufreq/ti-cpufreq.c | 10 ++++++++++ 1 file changed, 10 insertions(+) -- 2.34.1
