2023-12-15mei: rework Kconfig dependenciesArnd Bergmann4-11/+9
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.

2023-12-15mei: fix vsc dependencyArnd Bergmann1-0/+1
CONFIG_INTEL_MEI_VSC_HW can be set to built-in even with CONFIG_MEI=m, but then the driver is not built because Kbuild never enters the drivers/misc/mei directory for built-in files, leading to a link failure: ERROR: modpost: "vsc_tp_reset" [drivers/misc/mei/mei-vsc.ko] undefined!

Add an explicit dependency on CONFIG_MEI that was apparently missing, to ensure the VSC_HW driver cannot be built-in with MEI itself being a loadable module.

2023-12-15mei: vsc: Rework firmware image namesSakari Ailus1-62/+10
Rework firmware image names with the users in mind---there's no need for variation between firmware names, apart from connected sensors. All supported SoCs use the same firmware, too. Use a single set of firmware binaries and assume they'll be found under intel/vsc directory.

2023-12-07mei: Add transport driver for IVSC deviceWentong Wu5-0/+1442
The Intel visual sensing controller (IVSC) device is designed to control the camera sharing between host IPU for media usage and IVSC for context sensing (face detection). IVSC is exposed to HOST as an SPI device and the message protocol over the SPI BUS for communicating with the IVSC device is implemented. This is the backend of mei framework for IVSC device, which usually handles the hardware data transfer. The mei_csi and mei_ace are the clients of IVSC mei framework. The firmware downloading for the IVSC device is implemented as well.

GSC devices perform legal firmware initiated resets due to state transition that may appear as unexpected to the driver. Lower the log level for those devices to debug level and save the firmware status registers. When the device comes out of the reset it is possible to check whether the resets was due to a firmware error or an exception and only than produce a warning.

This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant.

A driver for a device on MEI bus can try to bind to the device right between bus attempt to remove driver and device structures removal.
