71c3a888cb powerpc updates for 5.6
- Implement user_access_begin() and friends for our platforms that support
    controlling kernel access to userspace.
 
  - 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.

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.

cef7298262 ARM: DT updates for v5.4
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.

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"

spi: mt7621: Move SPI driver out of staging
This patch moves the MT7621 SPI driver, which is used on some Ralink /
MediaTek MT76xx MIPS SoC's, out of the staging directory. No changes to
the source code are done in this patch.

This driver version was tested successfully on an MT7688 based platform
with an SPI NOR on CS0 and an SPI NAND on CS1 without any issues (so
far).

This patch also documents the devicetree bindings for the MT7621 SPI
device driver.

dt-bindings: snps,dw-apb-ssi: Add mandatory clock bindings documentation
The Synopsys SSI driver uses a mandatory clock that is not documented,
so detail it in the device tree bindings. Also correct the spelling of
"pins" in the "Optional Properties" section for the driver.

spi: spi-fsl-spi: support use of the SPISEL_BOOT signal on MPC8309
The MPC8309 has a dedicated signal, SPISEL_BOOT, usually used as chip
select for the flash device from which the bootloader is loaded. It is
not an ordinary gpio, but is simply controlled via the SPI_CS register
in the system configuration.

To allow accessing such a spi slave, we need to teach
fsl_spi_cs_control() how to control the SPISEL_BOOT signal. To
distinguish the gpio-controlled slaves, continue to have those use
chip_select values of 0..ngpios-1, and use chip_select == ngpios for
the boot flash.

I'm not too happy with all the ifdeffery, but it seems to be necessary
for guarding the sysdev/fsl_soc.h and use of
get_immrbase() (spi-fsl-lib.c already contains similar ifdeffery).

Googling suggests that the MPC8306 is similar, with the SPI_CS
register at the same offset.
