Stephan Gerhold 52d8e7f864 dt-bindings: iio: kionix,kxcjk1013: Document kionix,kx023-1025
The KX023-1025 accelerometer uses similar register bits as kxcjk1023,
so it can make use of the same driver. Document the new kionix,kx023-1025
compatible that is also supported by the kxcjk-1013 driver now.

Krzysztof Kozlowski 347978983b dt-bindings: iio: afe: current-sense-shunt: add io-channel-cells
The current-sense-shunt is an IIO provider thus can be referenced by IIO
consumers (via "io-channels" property in consumer device node).
Such provider is required to describe number of cells used in phandle
lookup with "io-channel-cells" property.  This also fixes dtbs_check
warnings like:

  arch/arm/boot/dts/s5pv210-fascinate4g.dt.yaml: current-sense-shunt:
    '#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+'

Jonathan Cameron 2cd2b093e4 dt-bindings:iio:adc:adi,ad7476: Add missing binding document
This binding covers class of simple SPI ADCs which only provide

The only real variation between them is over how many supplies they
use and which one is used for the reference.

falls under the catch all MAINTAINERS entry for ADI devices.

Linus Torvalds 939b7cbc00 RISC-V Patches for the 5.13 Merge Window, Part 1
* Support for the memtest= kernel command-line argument.
 * Support for building the kernel with FORTIFY_SOURCE.
 * Support for generic clockevent broadcasts.
 * Support for the buildtar build target.
 * Some build system cleanups to pass more LLVM-friendly arguments.
 * Support for kprobes.
 * A rearranged kernel memory map, the first part of supporting sv48
   systems.
 * Improvements to kexec, along with support for kdump and crash kernels.
 * An alternatives-based errata framework, along with support for
   handling a pair of errata that manifest on some SiFive designs
   (including the HiFive Unmatched).
 * Support for XIP.
 * A device tree for the Microchip PolarFire ICICLE SoC and associated
   dev board.
 
 Along with a bunch of cleanups.  There are already a handful of fixes
 on the list so there will likely be a part 2.

Add a binding description for Realtek's GPIO controller found on several
of their MIPS-based SoCs (codenamed Otto), such as the RTL838x and
RTL839x series of switch SoCs.

A fallback binding 'realtek,otto-gpio' is provided for cases where the
actual port ordering is not known yet, and enabling the interrupt
controller may result in uncaught interrupts.

Linus Torvalds 8796ac1d03 remoteproc updates for v5.13
This adds support to the remoteproc core for detaching Linux from a
 running remoteproc, e.g. to reboot Linux while leaving the remoteproc
 running, and it enable this support in the stm32 remoteproc driver.
 
 It also introduces a property for memory carveouts to track if they are
 iomem or system ram, to enable proper handling of the differences.
 
 The imx_rproc received a number of fixes and improvements, in particular
 support for attaching to already running remote processors and i.MX8MQ
 and i.MX8MM support.
 
 The Qualcomm wcss driver gained support for starting and stopping the
 wireless subsystem on QCS404, when not using the TrustZone-based
 validator/loader.
 
 Finally it brings a few fixes to the TI PRU and to the firmware loader
 for the Qualcomm modem subsystem drivers.

Geert Uytterhoeven 62b3b3660a dt-bindings: PCI: rcar-pci-host: Document missing R-Car H1 support
scripts/checkpatch.pl -f drivers/pci/controller/pcie-rcar-host.c:

    WARNING: DT compatible string "renesas,pcie-r8a7779" appears un-documented -- check ./Documentation/devicetree/bindings/

Re-add the compatible value for R-Car H1, which was lost during the
json-schema conversion.  Make the "resets" property optional on R-Car
H1, as it is not present yet on R-Car Gen1 SoCs.

This modifies MAINTAINER's file to remove Dan Murphy's email that is
 bouncing (and does it globally). I hope that does not conflict too badly.

Linus Torvalds 4f9701057a IOMMU Updates for Linux v5.13
Including:
 
 	- Big cleanup of almost unsused parts of the IOMMU API by
 	  Christoph Hellwig. This mostly affects the Freescale PAMU
 	  driver.
 
 	- New IOMMU driver for Unisoc SOCs
 
 	- ARM SMMU Updates from Will:
 
 	  - SMMUv3: Drop vestigial PREFETCH_ADDR support
 	  - SMMUv3: Elide TLB sync logic for empty gather
 	  - SMMUv3: Fix "Service Failure Mode" handling
     	  - SMMUv2: New Qualcomm compatible string
 
 	- Removal of the AMD IOMMU performance counter writeable check
 	  on AMD. It caused long boot delays on some machines and is
 	  only needed to work around an errata on some older (possibly
 	  pre-production) chips. If someone is still hit by this
 	  hardware issue anyway the performance counters will just
 	  return 0.
 
 	- Support for targeted invalidations in the AMD IOMMU driver.
 	  Before that the driver only invalidated a single 4k page or the
 	  whole IO/TLB for an address space. This has been extended now
 	  and is mostly useful for emulated AMD IOMMUs.
 
 	- Several fixes for the Shared Virtual Memory support in the
 	  Intel VT-d driver
 
 	- Mediatek drivers can now be built as modules
 
 	- Re-introduction of the forcedac boot option which got lost
 	  when converting the Intel VT-d driver to the common dma-iommu
 	  implementation.
 
 	- Extension of the IOMMU device registration interface and
 	  support iommu_ops to be const again when drivers are built as
 	  modules.
