Linus Torvalds a18d783fed Driver core patches for 4.19-rc1
Here are all of the driver core and related patches for 4.19-rc1.
 
 Nothing huge here, just a number of small cleanups and the ability to
 now stop the deferred probing after init happens.
 
 All of these have been in linux-next for a while with only a merge issue
 reported.  That merge issue is in fs/sysfs/group.c and Stephen has
 posted the diff of what it should be to resolve this.  I'll follow up
 with that diff to this pull request.

Linus Torvalds d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Sebastian Andrzej Siewior 23ebda2fc7 libata: remove ata_sff_data_xfer_noirq()
ata_sff_data_xfer_noirq() is invoked via the ->sff_data_xfer hook. The
latter is invoked by ata_pio_sector(), atapi_send_cdb() and
__atapi_pio_bytes() which in turn is invoked by ata_sff_hsm_move().
The latter function requires that the "ap->lock" lock is held which
needs to be taken with disabled interrupts.

There is no need have to have ata_sff_data_xfer_noirq() which invokes
ata_sff_data_xfer32() with disabled interrupts because at this point the
interrupts are already disabled.
Remove the function and its references to it and replace all callers
with ata_sff_data_xfer32().

Add a flag to autoremove the device links on supplier driver
unbind. This obviates the need to explicitly delete the link
in the remove path.
We remove these links only when the supplier's link to its
consumers has gone to DL_STATE_SUPPLIER_UNBIND state.

add similar flag for supplier later.

Srinivas Kandagatla abb9c9b8b5 slimbus: stream: add stream support
This patch adds support to SLIMbus stream apis for slimbus device.
SLIMbus streaming involves adding support to Data Channel Management and
channel Reconfiguration Messages to slim core plus few stream apis.
>From slim device side the apis are very simple mostly inline with other
stream apis.

Currently it only supports Isochronous and Push/Pull transport protocols,
which are sufficient for audio use cases.

Currently the code is split over various files with dma- prefixes in the
lib/ and drives/base directories, and the number of files keeps growing.
Move them into a single directory to keep the code together and remove
the file name prefixes.  To match the irq infrastructure this directory
is placed under the kernel/ directory.

This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
 xfcp, hisi_sas, cxlflash, qla2xxx.  In the absence of Nic, we're also
 taking target updates which are mostly minor except for the tcmu
 refactor. The only real core change to worry about is the removal of
 high page bouncing (in sas, storvsc and iscsi).  This has been well
 tested and no problems have shown up so far.

Linus Torvalds 6419945e33 This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
  - Round closest support for meson's mpll driver
  - Support for meson8b nand clocks and gxbb video decoder clocks
  - Mediatek mali clks
  - STM32MP1 fixes
  - Uniphier LD11/LD20 stream demux system clock

Linus Torvalds ea125dedbc This is the bulk of GPIO changes for the v4.18 development
cycle.
 
 Core changes:
 
 - We have killed off VLA from the core library and all drivers.
   The background should be clear for everyone at this point:
   https://lwn.net/Articles/749064/
   Also I just don't like VLA's, kernel developers hate it when
   compilers do things behind their back. It's as simple as that.
   I'm sorry that they even slipped in to begin with.
   Kudos to Laura Abbott for exorcising them.
 
 - Support GPIO hogs in machines/board files.
 
 New drivers and chip support:
 
 - R-Car r8a77470 (RZ/G1C)
 - R-Car r8a77965 (M3-N)
 - R-Car r8a77990 (E3)
 - PCA953x driver improvements to accomodate more variants.
 
 Improvements and new features:
 
 - Support one interrupt per line on port A in the DesignWare
   dwapb driver.
 
 Misc:
 
 - Random cleanups, right header files in the drivers, some
   size optimizations etc.

Bartosz Golaszewski a411e81e61 gpiolib: add hogs support for machine code
Board files constitute a significant part of the users of the legacy
GPIO framework. In many cases they only export a line and set its
desired value. We could use GPIO hogs for that like we do for DT and
ACPI but there's no support for that in machine code.

This patch proposes to extend the machine.h API with support for
registering hog tables in board files.

Andres Rodriguez 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.
