mei: hdcp: match without driver name

2024-01-31T00:19:59Z

Xe driver uses this component too, but current match function matches by i915 driver name. Remove dependency on i915 driver name in component_match function. Use PCI header information to match Intel graphics device.

mei: rework Kconfig dependencies

2023-12-15T16:02:15Z

The dependencies in the mei framework are inconsistent, with some symbols using 'select INTEL_MEI' to force it being enabled and others using 'depends on INTEL_MEI'. In general, one should not select user-visible symbols, so change all of these to normal dependencies, but change the default on INTEL_MEI to be enabled when building a kernel for an Intel CPU with ME or a generic x86 kernel. Having consistent dependencies makes the 'menuconfig' listing more readable by using proper indentation. A large if/endif block is just a simpler syntax than repeating the dependencies for each symbol.

mei: Move uuid.h to the MEI namespace

2023-03-23T16:25:46Z

There is only a single user of the UUID uAPI, let's make it part of that user. The way it's done is to prevent compilation time breakage for the user space that does #include In the future MEI user space tools can switch over to use mei_uuid.h.
