[PATCH v3 04/12] of: property: fw_devlink: Add support for renesas,scmi-firmware
From: Geert Uytterhoeven
Date: Wed Sep 02 2026 - 07:37:43 EST
Let fw_devlink create device links between consumers and suppliers of
SCMI firmware on Renesas platforms, and enforce these dependencies.
This prevents probing of drivers before the firmware they depend on
becomes available, thus avoiding unneeded probe deferrals.
