a32b344e6f This is the bulk of pin control changes for the v5.14 kernel: 
New drivers:
 
 - Last merge window we created a driver for the Ralink RT2880.
   We are now moving the Ralink SoC pin control drivers out of the MIPS
   architecture code and into the pin control subsystem. This concerns
   RT288X, MT7620, RT305X, RT3883 and MT7621.
 
 - Qualcomm SM6125 SoC pin control driver.
 
 - Qualcomm spmi-gpio support for PM7325.
 
 - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
 
 - Mediatek MT8365 SoC pin controller.
 
 - New device HID for the AMD GPIO controller.
 
 Improvements:
 
 - Pin bias config support for a slew of Renesas pin controllers.
 
 - Incremental improvements and non-urgent bug fixes to the Renesas
   SoC drivers.
 
 - Implement irq_set_wake on the AMD pin controller so we can wake
   up from external pin events.
 
 Misc:
 
 - Devicetree bindings for the Apple M1 pin controller, we will probably
   see a proper driver for this soon as well.

Merge tag 'pinctrl-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.14 kernel. Not so
  much going on. No core changes, just drivers.

  The most interesting would be that MIPS Ralink is migrating to pin
  control and we have some bindings but not yet code for the Apple M1
  pin controller.

  New drivers:

   - Last merge window we created a driver for the Ralink RT2880. We are
     now moving the Ralink SoC pin control drivers out of the MIPS
     architecture code and into the pin control subsystem. This concerns
     RT288X, MT7620, RT305X, RT3883 and MT7621.

   - Qualcomm SM6125 SoC pin control driver.

   - Qualcomm spmi-gpio support for PM7325.

   - Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)

   - Mediatek MT8365 SoC pin controller.

   - New device HID for the AMD GPIO controller.

  Improvements:

thermal: Use generic HW-protection shutdown API 
The hardware shutdown function was exported from kernel/reboot for
other subsystems to use. Logic is copied from the thermal_core. The
protection mutex is replaced by an atomic_t to allow calls also from
an IRQ context. Also the WARN() was replaced by pr_emerg() based on
discussions here:
https://lore.kernel.org/lkml/YJuPwAZroVZ%2Fw633@alley/
and here:
https://lore.kernel.org/linux-iommu/20210331093104.383705-4-geert+renesas@glider.be/

Use the exported API instead of implementing own just for the
thermal_core.

After seeing some users have subscription management trouble, more spam
than other Linux development lists, and considering some of the benefits
of kernel.org hosted lists, nvdimm and persistent memory development is
moving to nvdimm@lists.linux.dev.

The old list will remain up until v5.14-rc1 and shutdown thereafter.

Keep the textual reference to ch9.h as it was prior to commit
caa93d9bd2 ("usb: Fix up movement of USB core kerneldoc location").

As linux/usb/ch9.h does not contain comments anymore, explain
that drivers/usb/common/common.c includes such header and provides
declarations of a few utilities routines for manipulating the data types
from ch9.h. Also mention that drivers/usb/common/debug.c contains
some functions for creating debug output.

65ec0a7d24 This is the bulk of the pin control changes for the v5.13 kernel cycle 
Core changes:
 
 - A semantic change to handle pinmux and pinconf in explicit order
   while up until now we depended on the semantic order in the
   device tree. The device tree is a functional programming
   language and does not imply any order, so the right thing is
   for the pin control core to provide these semantics.
 
 - Add a new pinmux-select debugfs file which makes it possible to
   go in and select functions for a pin manually (iteratively, at
   the prompt) for debugging purposes.
 
 - Fixes to gpio regmap handling for a new pin control driver
   making use of regmap-gpio.
 
 - Use octal permissions on debugfs files.
 
 New drivers:
 
 - A massive rewrite of the former custom pin control driver for
   MIPS Broadcom devices to instead use the pin control subsystem.
   New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362,
   BCM6368, BCM63268 and BCM6318 SoC variants are implemented.
 
 - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and
   PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs
   on PM8008 are supported.
 
 - Support for the Rockchip RK3568/RK3566 pin controller.
 
 - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and
   X2000.
 
 - Support for Mediatek MTK8195.
 
 - Add a new Xilinx ZynqMP pin control driver.
 
 Driver improvements and non-urgent fixes:
 
 - Modularization and improvements of the Rockchip drivers.
 
 - Some new pins added to the description of new Renesas SoCs.
 
 - Clarifications of the GPIO base calculation in the Intel driver.
 
 - Fix the function names for the MPP54 and MPP55 pins in the Armada
   CP110 pin controller.
 
 - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
 
 - Support for ACPI probing of the Qualcomm SC8180x.
 
 - Fix interrupt clear status on rockchip
 
 - Fix some missing pins on the Ingenic JZ4770, some semantic
   fixes for the behaviour of the Ingenic pin controller.
   Add DMIC pins for JZ4780, X1000, X1500 and X1830.
 
 - A slew of janitorial like of_node_put() calls.

0c85556318 ARM: platform support for Apple M1 
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

37f00ab4a0 ARM: SoC drivers for v5.13 
Updates for SoC specific drivers include a few subsystems that
 have their own maintainers but send them through the soc tree:
 
 TEE/OP-TEE:
  -  Add tracepoints around calls to secure world
 
 Memory controller drivers:
  - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
  - Add debug statistics to Tegra20 memory controller
  - Update Tegra bindings and convert to dtschema
 
 ARM SCMI Firmware:
  - Support for modular SCMI protocols and vendor specific extensions
  - New SCMI IIO driver
  - Per-cpu DVFS
 
 The other driver changes are all from the platform maintainers
 directly and reflect the drivers that don't fit into any other
 subsystem as well as treewide changes for a particular platform.
 
 SoCFPGA:
  - Various cleanups contributed by Krzysztof Kozlowski
 
 Mediatek:
  - add MT8183 support to mutex driver
  - MMSYS: use per SoC array to describe the possible routing
  - add MMSYS support for MT8183 and MT8167
  - add support for PMIC wrapper with integrated arbiter
  - add support for MT8192/MT6873
 
 Tegra:
  - Bug fixes to PMC and clock drivers
 
 NXP/i.MX:
  - Update SCU power domain driver to keep console domain power on.
  - Add missing ADC1 power domain to SCU power domain driver.
  - Update comments for single global power domain in SCU power domain
    driver.
  - Add i.MX51/i.MX53 unique id support to i.MX SoC driver.
 
 NXP/FSL SoC driver updates for v5.13
  - Add ACPI support for RCPM driver
  - Use generic io{read,write} for QE drivers after performance optimized
    for PowerPC
  - Fix QBMAN probe to cleanup HW states correctly for kexec
  - Various cleanup and style fix for QBMAN/QE/GUTS drivers
 
 OMAP:
  - Preparation to use devicetree for genpd
  - ti-sysc needs iorange check improved when the interconnect target module
    has no control registers listed
  - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
    issues with missing resources and unnecessary deferred probe
  - ti-sysc debug option can now detect more devices
  - ti-sysc now warns if an old incomplete devicetree data is found as we
    now rely on it being complete for am3 and 4
  - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
  - omap-prm driver needs to enable autoidle retention support for omap4
  - omap5 clocks are missing gpmc and ocmc clock registers
  - pci-dra7xx now needs to use builtin_platform_driver instead of using
    builtin_platform_driver_probe for deferred probe to work
 
 Raspberry Pi:
  - Fix-up all RPi firmware drivers so as for unbind to happen in an
    orderly fashion
  - Support for RPi's PoE hat PWM bus
 
 Qualcomm
  - Improved detection for SCM calling conventions
  - Support for OEM specific wifi firmware path
  - Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP

 	- removal of unused and orphaned old-style serial drivers.  If
 	  anyone shows up with this hardware, it is trivial to restore
 	  these but we really do not think they are in use anymore.
 	- fixes and cleanups from Johan Hovold on a number of termios
 	  setting corner cases that loads of drivers got wrong as well
 	  as removing unneeded code due to tty core changes from long
 	  ago that were never propagated out to the drivers
 	- loads of platform-specific serial port driver updates and
 	  fixes
 	- coding style cleanups and other small fixes and updates all

8900d92fd6 Staging/IIO driver updates for 5.13-rc1 
Here is the big set of staging and IIO driver updates for 5.13-rc1.
 
 Lots of little churn in here, and some larger churn as well.  Major
 things are:
 	- removal of wimax drivers, no one has this hardware anymore for
 	  this failed "experiment".
 	- removal of the Google gasket driver, turns out no one wanted
 	  to maintain it or cares about it anymore, so they asked for it
 	  to be removed.
 	- comedi finally moves out of the staging directory into
 	  drivers/comedi/  This is one of the oldest kernel subsystems
 	  around, being created in the 2.0 kernel days, and was one of
 	  the first things added to drivers/staging/ when that was
 	  created over 15 years ago.  It should have been moved out of
 	  staging a long time ago, it's well maintained and used by
 	  loads of different devices in the real world every day.  Nice
 	  to see this finally happen.
 	- so many tiny coding style cleanups it's not funny.  Perfect
 	  storm of at least 2 different intern project application
 	  deadlines combined to provide a huge number of new
 	  contributions in this area from people learning how to do
 	  kernel development.  Great job to everyone involved here.
 
 There's also the normal updates for IIO drivers with new IIO drivers and
 updates all over that subsystem.
 
 All of these have been in linux-next for a while with no reported
 issues.

a6efb35019 pwm: Reword docs about pwm_apply_state() 
The main issue is that the current documentation talks about the
non-existent function pwm_get_last_applied_state. (This was right in the
context of
https://lore.kernel.org/linux-pwm/20210406073036.26857-1-u.kleine-koenig@pengutronix.de/
but was then missed to adapt when this patch was reduced to a
documentation update.)

While at is also clarify "last applied PWM state" to "PWM state that was
passed to the last invocation of pwm_apply_state()" to better
distinguish to the last actually implemented state and reword to drop a
word repetition.

caa93d9bd2 usb: Fix up movement of USB core kerneldoc location 
Commit 855b35ea96c4 ("usb: common: move function's kerneldoc next to its
definition") moved the USB common function documentation out of the
linux/usb/ch9.h header file into drivers/usb/common/common.c and
drivers/usb/common/debug.c, which causes the following 'make htmldocs'
build warning:

include/linux/usb/ch9.h:1: warning: no structured comments found

Fix that up by pointing the documentation at the correct location.

1a7a6e8072 pwm: Clarify which state pwm_get_state() returns 
Given that lowlevel drivers usually cannot implement exactly what a
consumer requests with pwm_apply_state() there is some rounding
involved.

pwm_get_state() returns the setting that was requested most recently by
the consumer (opposed to what was actually implemented in hardware in
reply to the last request). Clarify this in the function kerneldoc.

7c566bb5e4 asm-generic/io.h: Add a non-posted variant of ioremap() 
ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.

sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.

This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.

Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.
