With the qcom_smd_open_channel() API we allow SMD devices to open
additional SMD channels, to allow implementation of multi-channel SMD
devices - like Bluetooth.
Channels are opened from the same edge as the calling SMD device is tied
to.

Pull module_platform_driver replacement from Paul Gortmaker:
"Replace module_platform_driver with builtin_platform driver in non
modules.
We see an increasing number of non-modular drivers using
modular_driver() type register functions. There are several downsides
to letting this continue unchecked:
- The code can appear modular to a reader of the code, and they won't
know if the code really is modular without checking the Makefile
and Kconfig to see if compilation is governed by a bool or
tristate.
- Coders of drivers may be tempted to code up an __exit function that
is never used, just in order to satisfy the required three args of
the modular registration function.
- Non-modular code ends up including the <module.h> which increases
CPP overhead that they don't need.
- It hinders us from performing better separation of the module init
code and the generic init code.
So here we introduce similar macros for builtin drivers. Then we
convert builtin drivers (controlled by a bool Kconfig) by making the
following type of mapping:
module_platform_driver() ---> builtin_platform_driver()
module_platform_driver_probe() ---> builtin_platform_driver_probe().
The set of drivers that are converted here are just the ones that
showed up as relying on an implicit include of <module.h> during a
pending header cleanup. So we convert them here vs adding an include
of <module.h> to non-modular code to avoid compile fails. Additonal
conversions can be done asynchronously at any time.
Once again, an unused module_exit function that is removed here
appears in the diffstat as an outlier wrt all the other changes"

The ifc6410 firmware always enters the kernel in ARM state from
deep idle. Use the cpu_resume_arm() wrapper instead of
cpu_resume() to property switch into the THUMB2 state when we
wake up from idle.
This fixes a problem reported by Kevin Hilman on next-20150601
where the ifc6410 fails to boot a THUMB2 kernel because the
platform's firmware always enters the kernel in ARM mode from
deep idle states.

This file depends on Kconfig SOC_REALVIEW which is a bool, so
we use the appropriate registration function, which avoids us
relying on an implicit inclusion of <module.h> which we are
doing currently.
While this currently works, we really don't want to be including
the module.h header in non-modular code, which we'd be forced
to do, pending some upcoming code relocation from init.h into
module.h. So we fix it now by using the non-modular equivalent.

The Allwinner SoCs have a handful of SRAM that can be either mapped to be
accessible by devices or the CPU.
That mapping is controlled by an SRAM controller, and that mapping might
not be set by the bootloader, for example if the device wasn't used at all,
or if we're using solutions like the U-Boot's Falcon Boot.
We could also imagine changing this at runtime for example to change the
mapping of these SRAMs to use them for suspend/resume or runtime memory
rate change, if that ever happens.
These use cases require some API in the kernel to control that mapping,
exported through a drivers/soc driver.
This driver also implement a debugfs file that shows the SRAM found in the
system, the current mapping and the SRAM that have been claimed by some
drivers in the kernel.

When the PMIC wrapper state machine has read a register it goes into the
"wait for valid clear" (vldclr) state. The state machine stays in this
state until the VLDCLR bit is written to. We should write this bit after
reading a register because the SCPSYS won't let the system go into
suspend as long as the state machine waits for valid clear.
Since now we never leave the state machine in vldclr state we no longer
have to check for this state on pwrap_read/pwrap_write entry and can
remove the corresponding code.

replace chipselect extension values based on SPI clock with hardcoded SoC
specific values.
The PMIC wrapper has the ability of extending the chipselects by configurable
amounts of time. We configured the values based on the rate of SPI clock, but
this is wrong. The delays should be configured based on the internal PMIC clock
that latches the values from the SPI bus to the internal PMIC registers. By
default this clock is 24MHz. Other clock frequencies are for debugging only
and can be removed from the driver.

SPM is a hardware block that controls the peripheral logic surrounding
the application cores (cpu/l$). When the core executes WFI instruction,
the SPM takes over the putting the core in low power state as
configured. The wake up for the SPM is an interrupt at the GIC, which
then completes the rest of low power mode sequence and brings the core
out of low power mode.
The SPM has a set of control registers that configure the SPMs
individually based on the type of the core and the runtime conditions.
SPM is a finite state machine block to which a sequence is provided and
it interprets the bytes and executes them in sequence. Each low power
mode that the core can enter into is provided to the SPM as a sequence.
Configure the SPM to set the core (cpu or L2) into its low power mode,
the index of the first command in the sequence is set in the SPM_CTL
register. When the core executes ARM wfi instruction, it triggers the
SPM state machine to start executing from that index. The SPM state
machine waits until the interrupt occurs and starts executing the rest
of the sequence until it hits the end of the sequence. The end of the
sequence jumps the core out of its low power mode.
Add support for an idle driver to set up the SPM to place the core in
Standby or Standalone power collapse mode when the core is idle.

This adds support for the PMIC wrapper found on MediaTek MT8135 and
MT8173 SoCs. The PMIC wrapper is found on MT6xxx SoCs aswell but these
are currently not supported.
On MediaTek MT8135, MT8173 and other SoCs the PMIC is connected via
SPI. The SPI master interface is not directly visible to the CPU, but
only through the PMIC wrapper inside the SoC. The communication between
the SoC and the PMIC can optionally be encrypted. Also a non standard
Dual IO SPI mode can be used to increase speed. The MT8135 also supports
a special feature named "IP Pairing". With IP Pairing the pins of some
SoC internal peripherals can be on the PMIC. The signals of these pins
are routed over the SPI bus using the pwrap bridge. Because of these
optional non SPI conform features the PMIC driver is not implemented as
a SPI bus master driver.

because of circular dependency. So combine these two into one module
by changing the makefile.

Currently only few of the API calls are exported. This creates problem
when the knav* modules are built as modules and another user module
such as netcp_core try to use these API calls and they are also built
as module. This patch export these APIs to address the issue.
This is needed to support allmodconfig for ARM

This adds a device tree controlled option to enable PMC-based
thermal reset in overheating situations. Thermtrip is supported on
Tegra30, Tegra114 and Tegra124. The thermal reset only works when
the thermal sensors are calibrated, so a soctherm driver is also
required.
The thermtrip event is triggered by the soctherm block, and all
soctherm sensors default to showing a temperature of zero Celsius
before they are initialized. Because of this, it is safe to initialize
thermtrip and soctherm in any order.

Tegra132 uses the same GPU as Tegra124 and therefore requires the same
method to remove clamps. However Tegra132 has a separate chip ID, so in
order to avoid having to extend the list of chip IDs for the special
case, add a feature flag to the SoC data.

Tegra132 is very similar to Tegra124 from a peripheral point of view and
uses the same fuse controller.

These structures contain read-only data and are never modified, so they
can be const.
