Linus Torvalds a409ed156a This is the bulk of the GPIO changes for the v5.11 kernel cycle: 
Core changes:
 
 - Retired the old set-up function for GPIO IRQ chips. All chips
   now use the template struct gpio_irq_chip and pass that to the core
   to be set up alongside the gpio_chip. We can finally get rid of
   the old cruft.
 
 - Some refactoring and clean up of the core code.
 
 - Support edge event timestamps to be stamped using REALTIME
   (wall clock) timestamps. We have found solid use cases for
   this, so we support it.
 
 New drivers:
 
 - MStar MSC313 GPIO driver.
 
 - HiSilicon GPIO driver.
 
 Driver improvements:
 
 - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
 
 - The mockup driver can now be probed from the device tree which
   is pretty useful for virtual prototyping of devices.
 
 - The Rcar driver now supports .get_multiple()
 
 - The MXC driver dropped some legacy and became a pure device
   tree client.
 
 - The Exar driver was moved over to the IDA interface for
   enumerating, and also switched over to using regmap for
   register access.

     Generic NAND layer.
   - Entire rework of the software Hamming ECC driver, creation of a
     real ECC engine, getting rid of raw NAND structures, misc renames,
     comment updates, cleanup, and style fixes. Moved now to the
     generic NAND layer.

Geoff Levand c18e68696f net/connector: Add const qualifier to cb_id 
The connector driver never modifies any cb_id passed to it, so add a const
qualifier to those arguments so callers can declare their struct cb_id as a
constant object.

Fixes build warnings like these when passing a constant struct cb_id:

  warning: passing argument 1 of ‘cn_add_callback’ discards ‘const’ qualifier from pointer target

Linus Torvalds ee249d30fa Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input 
Pull input updates from Dmitry Torokhov:

 - support for inhibiting input devices at request from userspace. If a
   device implements open/close methods, it can also put device into low
   power state. This is needed, for example, to disable keyboard and
   touchpad on convertibles when they are transitioned into tablet mode

 - now that ordinary input devices can be configured for polling mode,
   dedicated input polling device implementation has been removed

 - GTCO tablet driver has been removed, as it used problematic custom
   HID parser, devices are EOL, and there is no interest from the
   manufacturer

 - a new driver for Dialog DA7280 haptic chips has been introduced

 - a new driver for power button on Dell Wyse 3020

 - support for eKTF2132 in ektf2127 driver

 - support for SC2721 and SC2730 in sc27xx-vibra driver

 - enhancements for Atmel touchscreens, AD7846 touchscreens, Elan
   touchpads, ADP5589, ST1232 touchscreen, TM2 touchkey drivers

 - fixes and cleanups to allow clean builds with W=1

Linus Torvalds edd7ab7684 The new preemtible kmap_local() implementation: 
- Consolidate all kmap_atomic() internals into a generic implementation
     which builds the base for the kmap_local() API and make the
     kmap_atomic() interface wrappers which handle the disabling/enabling of
     preemption and pagefaults.
 
   - Switch the storage from per-CPU to per task and provide scheduler
     support for clearing mapping when scheduling out and restoring them
     when scheduling back in.
 
   - Merge the migrate_disable/enable() code, which is also part of the
     scheduler pull request. This was required to make the kmap_local()
     interface available which does not disable preemption when a mapping
     is established. It has to disable migration instead to guarantee that
     the virtual address of the mapped slot is the same accross preemption.
 
   - Provide better debug facilities: guard pages and enforced utilization
     of the mapping mechanics on 64bit systems when the architecture allows
     it.
 
   - Provide the new kmap_local() API which can now be used to cleanup the
     kmap_atomic() usage sites all over the place. Most of the usage sites
     do not require the implicit disabling of preemption and pagefaults so
     the penalty on 64bit and 32bit non-highmem systems is removed and quite
     some of the code can be simplified. A wholesale conversion is not
     possible because some usage depends on the implicit side effects and
     some need to be cleaned up because they work around these side effects.
 
     The migrate disable side effect is only effective on highmem systems
     and when enforced debugging is enabled. On 64bit and 32bit non-highmem
     systems the overhead is completely avoided.

the conversion functions.

Try to clarify things a bit and hopefully make that section more

There's an effort to move the remove() callback in the driver core to
not return an int, as nothing can be done if this function fails.  To
make that effort easier, make the aux bus remove function void to start
with so that no users have to be changed sometime in the future.

Dave Ertman 7de3697e9c Add auxiliary bus support 
Add support for the Auxiliary Bus, auxiliary_device and auxiliary_driver.
It enables drivers to create an auxiliary_device and bind an
auxiliary_driver to it.

The bus supports probe/remove shutdown and suspend/resume callbacks.
Each auxiliary_device has a unique string based id; driver binds to
an auxiliary_device based on this id through the bus.

The register definitions as well as the definitions of this data structure
are generated from a text file using a Perl script. Add the generator
script to make it easy to update the generated files.

Bartosz Golaszewski fdcfd85433 rtc: rework rtc_register_device() resource management 
rtc_register_device() is a managed interface but it doesn't use devres
by itself - instead it marks an rtc_device as "registered" and the devres
callback for devm_rtc_allocate_device() takes care of resource release.

This doesn't correspond with the design behind devres where managed
structures should not be aware of being managed. The correct solution
here is to register a separate devres callback for unregistering the
device.

While at it: rename rtc_register_device() to devm_rtc_register_device()
and add it to the list of managed interfaces in devres.rst. This way we
can avoid any potential confusion of driver developers who may expect
there to exist a corresponding unregister function.

rtc_nvmem_register() is a managed interface. It doesn't require any
release function to be called at driver detach. To avoid confusing
driver authors, let's rename it to devm_rtc_nvmem_register() and add it
to the list of managed interfaces in Documentation/.

Raw camera sensors connected to parallel or CSI-2 busses need to implement

accordingly.

Document this. Also say V4L2_CID_PIXEL_RATE is recommended for such
hardware.

Lukasz Luba 5a64f77569 PM: EM: Clarify abstract scale usage for power values in Energy Model 
The Energy Model (EM) can store power values in milli-Watts or in abstract
scale. This might cause issues in the subsystems which use the EM for
estimating the device power, such as:

 - mixing of different scales in a subsystem which uses multiple
   (cooling) devices (e.g. thermal Intelligent Power Allocation (IPA))

 - assuming that energy [milli-Joules] can be derived from the EM power
   values which might not be possible since the power scale doesn't have
   to be in milli-Watts

To avoid misconfiguration add the requisite documentation to the EM and
related subsystems: EAS and IPA.
