ec064d3c6b Driver core changes for 4.18-rc1
Here is the driver core patchset for 4.18-rc1.
 
 The large chunk of these are firmware core documentation and api
 updates.  Nothing major there, just better descriptions for others to be
 able to understand the firmware code better.  There's also a user for a
 new firmware api call.
 
 Other than that, there are some minor updates for debugfs, kernfs, and
 the driver core itself.
 
 All of these have been in linux-next for a while with no reported
 issues.

7dcc01343e firmware: add firmware_request_nowarn() - load firmware without warnings
Currently the firmware loader only exposes one silent path for querying
optional firmware, and that is firmware_request_direct(). This function
also disables the sysfs fallback mechanism, which might not always be the
desired behaviour [0].

This patch introduces a variations of request_firmware() that enable the
caller to disable the undesired warning messages but enables the sysfs
fallback mechanism. This is equivalent to adding FW_OPT_NO_WARN to the
old behaviour.

ee3748be5c Driver core fixes for 4.17-rc3
Here are some small driver core and firmware fixes for 4.17-rc3
 
 There's a kobject WARN() removal to make syzkaller a lot happier about
 some "normal" error paths that it keeps hitting, which should reduce the
 number of false-positives we have been getting recently.
 
 There's also some fimware test and documentation fixes, and the
 coredump() function signature change that needed to happen after -rc1
 before drivers started to take advantage of it.
 
 All of these have been in linux-next with no reported issues.

1b2951dd99 This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
 
 - Nintendo Wii GameCube GPIO, known as "Hollywood"
 
 - Raspberry Pi mailbox service GPIO expander
 
 - Spreadtrum main SC9860 SoC and IEC GPIO controllers.
 
 Improvements:
 
 - Implemented .get_multiple() callback for most of the
   high-performance industrial GPIO cards for the ISA bus.
 
 - ISA GPIO drivers now select the ISA_BUS_API instead of
   depending on it. This is merged with the same pattern
   for all the ISA drivers and some other Kconfig cleanups
   related to this.
 
 Cleanup:
 
 - Delete the TZ1090 GPIO drivers following the deletion of
   this SoC from the ARM tree.
 
 - Move the documentation over to driver-api to conform with
   the rest of the kernel documentation build.
 
 - Continue to make the GPIO drivers include only
   <linux/gpio/driver.h> and not the too broad <linux/gpio.h>
   that we want to get rid of.
 
 - Managed to remove VLA allocation from two drivers pending
   more fixes in this area for the next merge window.
 
 - Misc janitorial fixes.

ac9053d2dc USB/PHY patches for 4.17-rc1
Here is the big set of USB and PHY driver patches for 4.17-rc1.
 
 Lots of USB typeC work happened this round, with code moving from the
 staging directory into the "real" part of the kernel, as well as new
 infrastructure being added to be able to handle the different types of
 "roles" that typeC requires.
 
 There is also the normal huge set of USB gadget controller and driver
 updates, along with XHCI changes, and a raft of other tiny fixes all
 over the USB tree.  And the PHY driver updates are merged in here as
 well as they interacted with the USB drivers in some places.
 
 All of these have been in linux-next for a while with no reported
 issues.

5d42c96e1c firmware: add firmware_request_cache() to help with cache on reboot
Some devices have an optimization in place to enable the firmware to
be retaineed during a system reboot, so after reboot the device can skip
requesting and loading the firmware. This can save up to 1s in load
time. The mt7601u 802.11 device happens to be such a device.

When these devices retain the firmware on a reboot and then suspend
they can miss looking for the firmware on resume. To help with this we
need a way to cache the firmware when such an optimization has taken
place.

bdecb33af3 usb: typec: API for controlling USB Type-C Multiplexers
USB Type-C connectors consist of various muxes and switches
that route the pins on the connector to the right locations.
The USB Type-C drivers need to be able to control the muxes,
as they are the ones that know things like the cable plug
orientation, and the current mode that was negotiated with
the partner.

This introduces a small API for registering and controlling
cable plug orientation switches, and separate small API for
registering and controlling pin multiplexer/demultiplexer
switches that are needed with Accessory/Alternate Modes.

f2d9b66d84 drivers: base: Unified device connection lookup
Several frameworks - clk, gpio, phy, pmw, etc. - maintain
lookup tables for describing connections and provide custom
API for handling them. This introduces a single generic
lookup table and API for the connections.

The motivation for this commit is centralizing the
connection lookup, but the goal is to ultimately extract the
connection descriptions also from firmware by using the
fwnode_graph_* functions and other mechanisms that are
available.
