Subject: [PATCH v3 00/10] Introducing firmware late binding

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.

v2:
 - Dropped voltage regulator specific code as binaries for it will not
   be available for upstreaming as of now.
 - Address review comments
v3:
 - Dropped fwctl patch for now
 - Added new patch to extract binary version
 - Address v2 review comments

Alexander Usyskin (2):
  mei: bus: add mei_cldev_mtu interface
  mei: late_bind: add late binding component driver
