Introducing firmware late binding feature to enable firmware loading for the devices, such as the fan controller and voltage regulator, during the driver probe. Typically, firmware for these devices are part of IFWI flash image but can be replaced at probe after OEM tuning.
This version (v8?): I'm covering for Badal's vacation since I'd like to take this as soon as possible to drm-xe-next. The changes in this version are mostly to address the valid Greg's concerns on the mei patches. In summary: - Proper commit messages - 'Late Binding' documentation and explanation - Proper code documentation, fixing word and style - Bring consistency to the prefixes and naming Previous revision history from Badal: https://lore.kernel.org/intel-xe/20250707191237.1782824-1-badal.nila...@intel.com Thanks, Rodrigo.
