We've had generic code handling module sysconfig and OCP reset registers
for omap variants for many years now and all the drivers really needs to
do is just call runtime PM functions.
Looks like the omap-hdq driver got only partially updated over the years
to use runtime PM, and still has lots of custom PM code left.
We can replace all the custom code for sysconfig, OCP reset, and PM with
just a few lines of runtime PM autosuspend code.
In order to set the device mode properly when pm_runtime_get_sync() is
called during probe, we need to also move parsing of "ti,mode" to happen
earlier before we call pm_runtime_enable().
Since we now disable interrupts lazily in omap_hdq_runtime_suspend(), we
must remove the call to hdq_disable_interrupt() in omap_w1_read_byte().
And we must clear irqstatus calling wait_event_timeout() on it, so let's
add hdq_reset_irqstatus() for that.
Note that the earlier driver specific usage count limit of four seems
completely artificial and should not be an issue in normal use.

Starting with SGI Origin machines nearly every new SGI ASIC contains
an 1-Wire master. They are used for attaching One-Wire prom devices,
which contain information about part numbers, revision numbers,
serial number etc. and MAC addresses for ethernet interfaces.
This patch adds a master driver to support this IP block.
It also adds an extra field dev_id to struct w1_bus_master, which
could be in used in slave drivers for creating unique device names.

- fix tables markups;
- add some lists markups;

- adjust title markups.

The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
call. It is very likely that the slave was not addressed properly and
it is just not respoding (leaving the bus in logic high state) during
the read of sampled PIO value.
We cannot just call w1_reset_resume_command() because the problem will
persist, instead try selecting (addressing) the slave again.

"Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small
driver subsystems" these days. Which is fine with me, if it makes
things easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported

>From the DS2408 datasheet [1]:
"Resume Command function checks the status of the RC flag and, if it is set,
directly transfers control to the control functions, similar to a Skip ROM
command. The only way to set the RC flag is through successfully executing
the Match ROM, Search ROM, Conditional Search ROM, or Overdrive-Match ROM
command"
The function currently works perfectly fine in a multidrop bus, but when we
have only a single slave connected, then only a Skip ROM is used and Match
ROM is not called at all. This is leading to problems e.g. with single one
DS2408 connected, as the Resume Command is not working properly and the
device is responding with failing results after the Resume Command.
This commit is fixing this by using a Skip ROM instead in those cases.
The bandwidth / performance advantage is exactly the same.

When we have success in 'Channel Access Write' but reading back latch
states fails, a write is retried without doing a proper slave reset.
This leads to protocol errors as the slave treats the next 'Channel
Access Write' as the continuation of previous command.
This commit is fixing this by making sure if the retry loop re-runs, a
reset is performed, whatever the failure (CONFIRM_BYTE or the read
back).
The loop was quite due for a cleanup and this change mandated it. By
isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
function, we vastly reduce the visual and branching(runtime and
compile-time) noise.

The syzkaller USB fuzzer spotted a slab-out-of-bounds bug in the
ds2490 driver. This bug is caused by improper use of the altsetting
array in the usb_interface structure (the array's entries are not
always stored in numerical order), combined with a naive assumption
that all interfaces probed by the driver will have the expected number
of altsettings.
The bug can be fixed by replacing references to the possibly
non-existent intf->altsetting[alt] entry with the guaranteed-to-exist
intf->cur_altsetting entry.

The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.
I do not see a good reason to complicate Kconfig for the room of
ambiguity.
The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.
Make it treewide consistent now.

This patch removes the w1 slave driver that used to register the w1 family
and instanciate a platform device at runtime. The code now lives in the
supply driver instead to avoid that level of indirection.
The old device name "ds2760-battery.0" is preserved, so userspace
applications can access the same virtual device nodes as before.
Note that because the w1 core does not currently have a framework for
suspend/resume, the driver now registers a PM notifier callback.
