[ Upstream commit 60b8f0ddf1a927ef02141a6610fd52575134f821 ]
This adds clk_get_optional() and devm_clk_get_optional() functions to get
optional clocks.
They behave the same as (devm_)clk_get() except where there is no clock
producer. In this case, instead of returning -ENOENT, the function
returns NULL. This makes error checking simpler and allows
clk_prepare_enable, etc to be called on the returned reference
without additional checks.

Pull clk updates from Stephen Boyd:
"We have two changes to the core framework this time around.
The first being a large change that introduces runtime PM support to
the clk framework. Now we properly call runtime PM operations on the
device providing a clk when the clk is in use. This helps on SoCs
where the clks provided by a device need something to be powered on
before using the clks, like power domains or regulators. It also helps
power those things down when clks aren't in use.
The other core change is a devm API addition for clk providers so we
can get rid of a bunch of clk driver remove functions that are just
doing of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and
smattering of non-critical fixes to existing drivers. The biggest diff
is support for Mediatek MT2712 and MT7622 SoCs, but those patches
really just add a bunch of data.
By the way, we're trying something new here where we build the tree up
with topic branches. We plan to work this into our workflow so that we
don't step on each other's toes, and so the fixes branch can be merged
on an as-needed basis.
Summary:
Core:
- runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()
New Drivers:
- Mediatek MT2712 and MT7622
- Renesas R-Car V3M SoC
Updates:
- runtime PM support for Samsung exynos5433/exynos4412 providers
- removal of clkdev aliases on Samsung SoCs
- convert clk-gpio to use gpio descriptors
- various driver cleanups to match kernel coding style
- Amlogic Video Processing Unit VPU and VAPB clks
- sigma-delta modulation for Allwinner audio PLLs
- Allwinner A83t Display clks
- support for the second display unit clock on Renesas RZ/G1E
- suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
- new clock ids for Rockchip rk3188 and rk3368 SoCs
- various 'const' markings on clk_ops structures
- RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

Sometimes we only have one of_clk_del_provider() call in driver
error and remove paths, because we're missing a
devm_of_clk_add_hw_provider() API. Introduce the API so we can
convert drivers to use this and potentially reduce the amount of
code needed to remove providers in drivers.

DRIVER_ATTR is no longer in use, and driver authors should be using
DRIVER_ATTR_RW() or DRIVER_ATTR_RO() or DRIVER_ATTR_WO() instead in
order to always get the permissions correct. So remove it so that no
one can use it anymore.

Pull dma-mapping infrastructure from Christoph Hellwig:
"This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls to
->mapping_error so that the dma_map_ops instances are more self

Add a new minimalistic subsystem that handles multiplexer controllers.
When multiplexers are used in various places in the kernel, and the
same multiplexer controller can be used for several independent things,
there should be one place to implement support for said multiplexer
controller.
A single multiplexer controller can also be used to control several
parallel multiplexers, that are in turn used by different subsystems
in the kernel, leading to a need to coordinate multiplexer accesses.
The multiplexer subsystem handles this coordination.

Wolfram Sang, Paul Gortmaker, Dan Carpenter, Colin Ian King, Greg

The introduction of the pci_remap_cfgspace() interface allows PCI host
controller drivers to map PCI config space through a dedicated kernel
interface. Current PCI host controller drivers use the devm_ioremap_*()
devres interfaces to map PCI configuration space regions so in order to
update them to the new pci_remap_cfgspace() mapping interface a new set of
devres interfaces should be implemented so that PCI host controller drivers
can make use of them.
Introduce two new functions in the PCI kernel layer and Devres
documentation:
- devm_pci_remap_cfgspace()
- devm_pci_remap_cfg_resource()
so that PCI host controller drivers can make use of them to map PCI
configuration space regions.

Pull staging and IIO updates from Greg KH:
"Here is the big staging and IIO driver pull request for 4.9-rc1.
There are a lot of patches in here, the majority due to the
drivers/staging/greybus/ subsystem being merged in with full
development history that went back a few years, in order to preserve
the work that those developers did over time.
Lots and lots of tiny cleanups happened in the tree as well, due to
the Outreachy application process and lots of other developers showing
up for the first time to clean code up. Along with those changes, we
deleted a wireless driver, and added a raspberrypi driver (currently
marked broken), and lots of new iio drivers.
Overall the tree still shrunk with more lines removed than added,
about 10 thousand lines removed in total. Full details are in the very
long shortlog below.
All of this has been in the linux-next tree with no issues. There will
be some merge problems with other subsystem trees, but those are all
minor problems and shouldn't be hard to work out when they happen
(MAINTAINERS and some lustre build problems with the IB tree)"
And furter from me asking for clarification about greybus:
"Right now there is a phone from Motorola shipping with this code (a
slightly older version, but the same tree), so even though Ara is not
alive in the same form, the functionality is happening. We are working
with the developers of that phone to merge the newer stuff in with
their fork so they can use the upstream version in future versions of
their phone product line.
Toshiba has at least one chip shipping in their catalog that
needs/uses this protocol over a Unipro link, and rumor has it that
there might be more in the future.
There are also other users of the greybus protocols, there is a talk
next week at ELC that shows how it is being used across a network
connection to control a device, and previous ELC talks have showed the
protocol stack being used over USB to drive embedded Linux boards.
I've also talked to some people who are starting to work to add a host
controller driver to control arduinos as the greybus PHY protocols are
very useful to control a serial/i2c/spio/whatever device across a
random physical link, as it is a way to have a self-describing device
be attached to a host without needing manual configuration.
So yes, people are using it, and there is still the chance that it
will show up in a phone/laptop/tablet/whatever from Google in the
future as well, the tech isn't dead, even if the original large phone
project happens to be"

Pull clk updates from Stephen Boyd:
"It's the usual big pile of driver updates and additions, but we do
have a couple core changes in here as well.
Core:
- CLK_IS_CRITICAL support has been added. This should allow drivers
to properly express that a certain clk should stay on even if their
prepare/enable count drops to 0 (and in turn the parents of these
clks should stay enabled).
- A clk registration API has been added, clk_hw_register(), and an OF
clk provider API has been added, of_clk_add_hw_provider(). These
APIs have been put in place to further split clk providers from clk
consumers, with the goal being to have clk providers never deal
with struct clk pointers at all. Conversion of provider drivers is
on going. clkdev has also gained support for registering clk_hw
pointers directly so we can convert drivers that don't use
devicetree.

- Marvell ap806 and cp110 system controllers (with clks inside!)

We've largely split the clk consumer and provider APIs along
struct clk and struct clk_hw, but clk_register() still returns a
struct clk pointer for each struct clk_hw that's registered.
Eventually we'd like to only allocate struct clks when there's a
user, because struct clk is per-user now, so clk_register() needs
to change.
Let's add new APIs to register struct clk_hws, but this time
we'll hide the struct clk from the caller by returning an int
error code. Also add an unregistration API that takes the clk_hw
structure that was passed to the registration API. This way
provider drivers never have to deal with a struct clk pointer
unless they're using the clk consumer APIs.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel v4.6. There is quite a
lot of interesting stuff going on.
The patches to other subsystems and arch-wide are ACKed as far as
possible, though I consider things like per-arch <asm/gpio.h> as
essentially a part of the GPIO subsystem so it should not be needed.
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model.
We now finally make GPIO chips devices. The gpio_chip will create
a gpio_device which contains a struct device, and this gpio_device
struct is kept private. Anything that needs to be kept private
from the rest of the kernel will gradually be moved over to the
gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step of
a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices.
We can now discover GPIOs properly from userspace. We still have
not come up with a way to actually *use* GPIOs from userspace.
- To encourage people to use the character device for the future, we
have it always-enabled when using GPIO. The old sysfs ABI is still
opt-in (and can be used in parallel), but is marked as deprecated.
We will keep it around for the foreseeable future, but it will not
be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes.
This dates back to when GPIO was an opt-in feature and no shared
library even existed: just a header file with proper prototypes was
provided and all semantics were up to the arch to implement. These
patches make the GPIO chip even more a proper device and cleans out
leftovers of the old in-kernel API here and there.
Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going on,
but we now return sane values in the vast majority of drivers and
the errorpath is sanitized. Some patches for powerpc, blackfin and
unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected to
SPI to obtain a dirt-cheap output-only GPIO expander.
- Texas Instruments TPIC2810
- Texas Instruments TPS65218
- Texas Instruments TPS65912
- X-Gene (ARM64) standby GPIO controller"

Allow implementations of the match() callback in struct bus_type to
return errors and if it's -EPROBE_DEFER then queue the device for
deferred probing.
This is useful to buses such as AMBA in which devices are registered
before their matching information can be retrieved from the HW
(typically because a clock driver hasn't probed yet).
[changed if-else code structure, adjusted documentation to match the code,
extended comments]
