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: interface_block: s/gb_module/gb_interface_block/ Rename struct gb_module to struct gb_interface_block It's a complex rename, some functions got their name changed where needed, but primarily this change is focused on the structure and where it is used. Future changes will clean up the remaining usages of the term "module" in individual changes, this one spanned the whole subsystem so do it all at once.

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: October 1 updates Update the definitions in "greybus_manifest.h" to reflect the changes to the Greybus specification made on October 1. They are: - renaming "device" to be "interface" - renumbering greybus descriptor type - eliminating the notion of a "function" - defining a CPort's protocol in the CPort descriptor - having a "class" take on the types previously used for "function" - renaming "serial number" to be "unique id" (for now) - relying on an interface's maximum cport id to determine how much device+cport address space the interface consumes - adding a simple class descriptor - renaming gb_interface->interface_id to be gb_interface->id This also reorders some things to match ordering in the document, and adds some commentary for the various structures. Since greybus_function_type is gone, we eliminate the "type" field from a function structure. (Functions are going away, next.)
