Linus Torvalds 854e80bcfd Merge tag 'arm-dt-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM devicetree updates from Arnd Bergmann:
 "Most of the commits are for additional hardware support and minor
  fixes for existing machines for all the usual platforms: qcom,
  amlogic, at91, gemini, mediatek, ti, socfpga, i.mx, layerscape,
  uniphier, rockchip, exynos, ux500, mvebu, tegra, stm32, renesas,
  sunxi, broadcom, omap, and versatile.

  The conversion of binding files to machine-readable yaml format
  continues, along with fixes found during the validation. Andre
  Przywara takes over maintainership for the old Calxeda Highbank
  platform and provides a number of updates.

  The OMAP2+ platforms see a continued move from platform data into dts
  files, for many devices that relied on a mix of auxiliary data in
  addition to the DT description

  A moderate number of new SoCs and machines are added, here is a full
  list:

   - Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
     (SM8250) is the current high-end phone chip, and IPQ6018 is a new
     WiFi-6 router chip.

   - Mediatek MT8516 application processor SoC for voice assistants,
     along with the "pumpkin" development board

   - NXP i.MX8M Plus SoC, a variant of the popular i.MX8M, along with an
     evaluation board.

   - Kontron "sl28" board family based on NXP LS1028A

   - Eleven variations of the new i.MX6 TechNexion Pico board, combining
     the "dwarf", "hobbit", "nymph" and "pi" baseboards with i.MX6/i.MX7
     SoM carriers

   - Three additional variants of the Toradex Colibri board family, all
     based on versions of the NXP i.MX7.

   - The Pinebook Pro laptop based on Rockchip RK3399

   - Samsung S7710 Galaxy Xcover 2, a 2013 vintage Android phone based
     on the ST-Ericsson u8500 platform

   - DH Electronics DHCOM SoM and PDK2 rev. 400 carrier based on
     STMicroelectronics stm32mp157

   - Renesas M3ULCB starter kit for R-Car M3-W+

   - Hoperun HiHope development board with Renesas RZ/G2M

   - Pine64 PineTab tablet and PinePhone phone, both based on Allwinner
     A64

   - Linutronix Testbox v2 for the Lamobo R1 router, based on Allwinner
     A20

   - PocketBook Touch Lux 3 ebook reader, based on Allwinner A13"

Geert Uytterhoeven 30b435d54b spi: dt-bindings: spi-controller: Fix spi-[rt]x-bus-width for slave mode
The descriptions for the spi-rx-bus-width and spi-tx-bus-width
properties refer to "MISO" and "MOSI", which are not explained in the
document.  While these abbreviations are fairly common when talking
about SPI, and thus may not need an explanation, they are not entirely
correct in this context, as the SPI controller may be used in slave mode
instead of master mode.

Fix this by replacing them by "read transfers" resp. "write transfers",
like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

Geert Uytterhoeven a079ff858c spi: dt-bindings: spi-controller: Fix #address-cells for slave mode
Currently, the DT bindings for an SPI controller specify that
"#address-cells" must be fixed to one.  However, that applies to an SPI
controller in master mode only.  When running in SPI slave mode,
"#address-cells" should not be specified.

Fix this making "#address-cells" mutually-exclusive with "spi-slave".

spi: Rewrite mtk-quadspi spi-nor driver with spi-mem

This patchset from Chuanhong Guo <gch981213@gmail.com> adds a spi-mem
driver for Mediatek SPI-NOR controller, which already has limited
support by mtk-quadspi. This new driver can make use of full quadspi
capability of this controller.

Chuanhong Guo 13a971046a dt-bindings: convert mtk-quadspi binding doc for spi-mtk-nor
spi-mtk-nor is a driver to replace mtk-quadspi and they have almost
the same device-tree bindings. Reuse this binding documentation and
convert it for new driver:

1. "Mediatek SoCs" -> "Mediatek ARM SoCs" because MTK MIPS SoCs
   use different controllers.
2. document "interrupts" as a required property because it's
   available on all SoCs with this controller and new driver takes
   advantages of it. It's implemented as optional only to maintain
   backward compatibility.
3. add a dummy interrupt binding in example.

Mark Brown cb71d8efd7 Merge series "Compatible string consolidation for NXP DSPI driver" from Vladimir Oltean <olteanv@gmail.com>:
This series makes room in the driver for differentiation between the
controllers which currently operate in TCFQ mode. Most of these are
actually capable of a lot more in terms of throughput. This is in
preparation of a second series which will convert the remaining users of
TCFQ mode altogether to XSPI mode with command cycling.

Vladimir Oltean 50b62071de spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCs
Make the second compatible string optional for LS1012A, LS1088A and
LS2080A. Old versions of the spi-fsl-dspi.c driver still need to probe
on the old, generic compatible string for these controllers (such as
"fsl,ls1021a-v1.0-dspi") which provides less functionality.

Document the device tree bindings for LS1043A and LS1046A, whose
bindings are already in use in fsl-ls1043a.dtsi and fsl-ls1046a.dtsi.

Introduce new compatible strings for LS1028A and LX2160A. There will be
no second compatible string for these.

   - Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx.

   - Some tweaks to our pseries IOMMU code to allow SVMs ("secure"
     virtual machines) to use the IOMMU.

   - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit
     VDSO, and some other improvements.

   - A series to use the PCI hotplug framework to control opencapi
     card's so that they can be reset and re-read after flashing a new
     FPGA image.

  As well as other minor fixes and improvements as usual.

Phil Edworthy da182a61fc dt: spi: Add Renesas RZ/N1 binding documentation
The Renesas RZ/N1 SPI Controller is based on the Synopsys DW SSI, but has
additional registers for software CS control and DMA. This patch does not
address the changes required for DMA support, it simply adds the compatible
string. The CS functionality is not very useful and also not needed as
Linux can use gpios for the CS signals.

Add a compatible string to handle any unforeseen issues that may arise, and
pave the way for DMA support.

Linus Torvalds cef7298262 Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM DT updates from Arnd Bergmann:
 "This is another huge branch with close to 450 changessets related to
  devicetree files, roughly half of this for 32-bit and 64-bit
  respectively. There are lots of cleanups and additional hardware
  support for platforms we already support based on SoCs from Renesas,
  ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
  other manufacturers.

  A total of 6 new SoCs and 37 new boards gets added this time, one more
  SoC will come in a follow-up branch. Most of the new boards are for
  64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.

  Going more into details for SoC platforms with new hardware support:

   - The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
     platform, usually paired with an external 5G modem. So far we only
     support the Qualcomm SM8150 MTP reference platform, but no actual
     products.

   - For the slightly older Qualcomm platforms, support for several
     interesting products is getting added: Three laptops based on
     Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
     630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
     and several phones based on the older Snapdragon 410/MSM8916
     (Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
     aka Wileyfox Swift).

   - Mediatek MT7629 is a new wireless network router chip, similar to
     the older MT7623. It gets added together with the reference board
     implementation.

   - Allwinner V3 is a repackaged version of the existing low-end V3s
     chip, and is used in the tiny Lichee Pi Zero plus, also added here.
     There is also a new TV set-top box based on Allwinner H6, the Tanix
     TX6, and the eMMC variant of the Olimex A64-Olinuxino development
     board.

   - NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
     family, similar to the i.MX8M Mini. As usual, there is a large
     number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
     SolidRun Hummingboard Pulse baseboard and System-on-Module,
     Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
     PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
     Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
     phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
     Innovations i.MX7 RMU2 board.

   - In a different NXP product line, the Layerscape LS1046A "Freeway"
     reference board gets added.

   - Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
     their set-top-box line and smart speaker with newer CPU and GPU
     cores compared to their predecessors. Both are now also supported
     by the Khadas VIM3 development board series, and the dts files for
     that get reorganized a bit to better deal with all variants.
     Another board based on SM1 that gets added is the SEI Robotics
     SEI610.

   - There are a handful of new x86 and Power9 server boards using
     Aspeed BMC chips that are gaining support for running Linux on the
     BMC through the OpenBMC project: Facebook
     Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
     these are still new machines using SoCs based on the ARM9 and ARM11
     CPU cores, as support for the new Cortex-A7 based AST2600 is still
     ramping up.

   - There are three new end-user products using 32-bit Rockchips SoCs:
     Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
     low-end RK3229 chip, while the two AOpen products Chromebox Mini
     (Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
     commercial settings(digital signage, PoS, ...).

   - One more single-board computer based on the popular 64-bit RK3399
     is added: the Leez RK3399 P710"
