Early Platform Drivers in Linux Kernel
summary
Proposes a lightweight early platform driver framework that lets OF_DECLARE users register devices that run an early_probe callback very early and then get postcore init conversion into normal platform devices, so drivers can use usual device APIs and resource helpers instead of ad‑hoc OF callbacks. Series includes a working example and about 300 LOC of core code, supports DT and board files, allows probe deferral, and fixes a DaVinci clock/timer boot ordering issue; requires care because many frameworks aren’t available during early probes.
