The EC has specific timing it requires. Add support for an optional delay
after raising CS to fix timing issues. This is configurable based on
a DT property "google,cros-ec-spi-msg-delay".
If this property isn't set, then no delay will be added. However, if set
it will cause a delay equal to the value passed to it to be inserted at
the end of a transaction.

Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:
* TPS658623: Use correct voltage table for SM2
* TPS658643: New voltage table for SM2
Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.
This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.
On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.

This is the other of the LP3943 MFD driver.
LP3943 can be used as a PWM generator, up to 2 channels.
* Two PWM generators supported
* Supported PWM operations
request, free, config, enable and disable
* Pin assignment
A driver data, 'pin_used' is checked when a PWM is requested.
If the output pin is already assigned, then returns as failure.
If the pin is available, 'pin_used' is set.
When the PWM is not used anymore, then it is cleared.

LP3943 has 16 output pins which can be used as GPIO expander and PWM generator.
* Regmap I2C interface for R/W LP3943 registers
* Atomic operations for output pin assignment
The driver should check whether requested pin is available or not.
If the pin is already used, pin request returns as a failure.
A driver data, 'pin_used' is checked when gpio_request() and
pwm_request() are called. If the pin is available, then pin_used is set.
And it is cleared when gpio_free() and pwm_free().

* Application note: how to configure LP3943 as a GPIO expander
http://www.ti.com/lit/an/snva287a/snva287a.pdf
* Supported GPIO controller operations
request, free, direction_input, direction_output, get and set
* GPIO direction register not supported
LP3943 doesn't have the GPIO direction register. It only provides input and
output status registers.
So, private data for the direction should be handled manually.
This variable is updated whenever the direction is changed and
used in 'get' operation.
* Pin assignment
A driver data, 'pin_used' is checked when a GPIO is requested.
If the GPIO is already assigned, then returns as failure.
If the GPIO is available, 'pin_used' is set.

Add PM suspend/resume ops to the sec MFD core driver and make it a wake

broken interrupts after resuming:
[ 42.705703] sec_pmic 7-0066: Failed to read IRQ status: -5
Interrupts stop working after first resume initiated by them (e.g. by
RTC Alarm interrupt) because interrupt registers were not cleared properly.
When device is woken up from suspend by RTC Alarm, an interrupt occurs
before resuming I2C bus controller. The interrupt is handled by
regmap_irq_thread which tries to read RTC registers. This read fails
(I2C is still suspended) and RTC Alarm interrupt is disabled.
Disable the S5M8767 interrupts during suspend (disable_irq()) and enable
them during resume so the device will be still woken up but the interrupt
won't happen before resuming I2C bus.

Anton stated that he would have to abandon power supply maintainership
due to the lack of time. By agreement with him and David, pick up power
supply tree.

Pull x32 uapi changes from Peter Anvin:
"This is the first few of a set of patches by H.J. Lu to make the
kernel uapi headers usable for x32, as required by some non-glibc
libcs.
These particular patches make the stat and statfs structures usable"
* 'x86-x32-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, x32: Use __kernel_long_t for __statfs_word
x86, x32: Use __kernel_long_t/__kernel_ulong_t in x86-64 stat.h
Pull x86 cpufeature and mpx updates from Peter Anvin:
"This includes the basic infrastructure for MPX (Memory Protection
Extensions) support, but does not include MPX support itself. It is,
however, a prerequisite for KVM support for MPX, which I believe will
be pushed later this merge window by the KVM team.
This includes moving the functionality in
futex_atomic_cmpxchg_inatomic() into a new function in uaccess.h so it
can be reused - this will be used by the final MPX patches.
The actual MPX functionality (map management and so on) will be pushed
in a future merge window, when ready"
* 'x86/mpx' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/intel/mpx: Remove unused LWP structure
