Linus Torvalds f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Andrey Smirnov 925f8d4aad tools/firmware/ihex2fw: Replace explicit alignment with ALIGN
(X + 3) & ~3 is the same as ALIGN(X, 4), so replace all of the
instances of the formwer in the code with the latter. While at it,
introduce a helper variable 'record_size' to avoid duplicating length
calculatin code. No functional change intended.

Andrey Smirnov 2ef8179bb7 tools/firmware/ihex2fw: Simplify next record offset calculation
We can convert original expression for 'writelen" to use ALIGN as
follows:

    (p->len + 9) & ~3 => (p->len + 6 + 3) & ~3 => ALIGN(p->len + 6, 4)

Now, subsituting "p->len + 6" with "p->len + sizeof(p->addr) +
sizeof(p->len)" we end up with the same expression as used by kernel
couterpart in linux/ihex.h:

    ALIGN(p->len + sizeof(p->addr) + sizeof(p->len), 4)

That is a full size of the record, aligned to 4 bytes. No functional
change intended.

Andrey Smirnov 1e5106031f tools: Add 'firmware' category and add ihex2fw tool
Commit 5620a0d1aa ("firmware: delete in-kernel firmware") removed
ihex2fw tool together with the rest of the contents of firmware/
folder. Since that tool is quite useful for doing .ihex -> .fw
converstion, restore its original source code to tools/firmware
