greybus: isolate greybus module code Define new source files "module.h" and "module.c" to separate the definitions of the Greybus module abstraction from other code. Rename "greybus_module" to be "gb_module", for brevity. Do the same for a few other symbols with "greybus_module" in their names. A few (like greybus_module_id) are more visible outside this kernel module so we'll keep their names more descriptive. Add a definition for U8_MAX in "kernel_ver.h" (it appeared in 3.14).

greybus: add module support Modules in the greybus system sit above the interface, so insert them early in the sysfs tree. We dynamically create them when we have an interface that references a module, as we don't get a "module create" message directly. They also dynamically go away when the last interface associated with a module is removed. Naming scheme for modules/interfaces/bundles/connections is bumped up by one ':', and now looks like the following: /sys/bus/greybus $ tree . ├── devices │   ├── 7 -> ../../../devices/pci0000:00/0000:00:14.0/usb1/1-1/7 │   ├── 7:7 -> ../../../devices/pci0000:00/0000:00:14.0/usb1/1-1/7/7:7 │   ├── 7:7:0 -> ../../../devices/pci0000:00/0000:00:14.0/usb1/1-1/7/7:7/7:7:0 │   └── 7:7:0:1 -> ../../../devices/pci0000:00/0000:00:14.0/usb1/1-1/7/7:7/7:7:0/7:7:0:1 ├── drivers ├── drivers_autoprobe ├── drivers_probe └── uevent 6 directories, 3 files /sys/bus/greybus $ grep . devices/*/uevent devices/7/uevent:DEVTYPE=greybus_module devices/7:7/uevent:DEVTYPE=greybus_interface devices/7:7:0/uevent:DEVTYPE=greybus_bundle devices/7:7:0:1/uevent:DEVTYPE=greybus_connection We still have some "confusion" about interface ids and module ids, which will be cleaned up later when the svc control protocol changes die down, right now we just name a module after the interface as we don't have any modules that have multiple interfaces in our systems.

greybus: manifest: Use interface descriptor instead of module descriptor to get information A module can have more than one interfaces and we get hotplug events or manifests for interfaces, not modules. Details like version, vendor, product id, etc. can be different for different interfaces within the same module and so shall be fetched from interface descriptor instead of module descriptor. So what we have been doing for module descriptors until now must be done for interface descriptors. There can only be one interface descriptor in the manifest. Module descriptor isn't used anymore and probably most of its fields can be removed now. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>

/* Information taken from the manifest descriptor */
greybus: start improving manifest parsing Currently the module manifest parsing code is sort of representative only and is not really very useful. This patch begins doing "real" parsing of the module manifest. It scans the module manifest to identify the descriptors it holds. It then verifies there's only one module descriptor found, and initializes new some fields in the gb_module structure based on what it contains (converting what's found to native byte order). Note that if anything unexpected is found or other errors occur when parsing the manifest, the parse fails. Because we now save this converted information when it's parsed we no longer have a greybus_descriptor_module struct within a struct gb_module. And because we've already converted these values, we can do a little less work displaying values in sysfs. (We also now show vendor, product, and version values in the right byte order.) This eliminates the need for greybus_string(), so get rid of it. It also slightly simplifies the greybus module matching code. Move some existing parsing code into a new file, "manifest.c".

greybus: interface: declare gb_interface_destroy() Add a public declaration for gb_interface_destroy(), matching gb_interface_create(). It's not yet used outside "interface.c" but I suppose it could be, and its scope is currently public.
