Add support for the drive strength configuration. Usually, this value is
expressed in mA. Since the numeric value depends on VDDIOP voltage, a
value we can't retrieve at runtime, the controller uses low, medium and
high to define the drive strength.
The PIO controller accepts two values for the low drive configuration: 0
and 1. Most of the time, we don't care about the drive strength. So we
keep the default value which is 0. The drive strength is advertised
through the sysfs only when it has been explicitly set in the device
tree i.e. if its value is different from 0.

If you do this on an sdm845 board:
grep "" /sys/kernel/debug/pinctrl/*spmi:pmic*/pinconf-groups
...it looks like nonsense. For every pin you see listed:
input bias disabled, input bias high impedance, input bias pull down, input bias pull up, ...
That's because pmic_gpio_config_get() isn't complying with the rules
that pinconf_generic_dump_one() expects. Specifically for boolean
parameters (anything with a "struct pin_config_item" where has_arg is
false) the function expects that the function should return its value
not through the "config" parameter but should return "0" if the value
is set and "-EINVAL" if the value isn't set.
Let's fix this.
From a quick sample of other pinctrl drivers, it appears to be
tradition to also return 1 through the config parameter for these
boolean parameters when they exist. I'm not one to knock tradition,
so I'll follow tradition and return 1 in these cases. While I'm at
it, I'll also continue searching for four leaf clovers, kocking on
wood three times, and trying not to break mirrors.
NOTE: This also fixes an apparent typo for reading
PIN_CONFIG_BIAS_DISABLE where the old driver was accidentally
using "=" instead of "==" and thus was setting some internal
state when you tried to query PIN_CONFIG_BIAS_DISABLE. Oops.

Add suspend/resume hooks in pinctrl driver to handle S2RAM operations.
Beyond the traditional register save/restore operations, these hooks
also keep the GPIOs used for both-edge IRQ synchronized between their
level (low/high) and expected IRQ polarity (falling/rising edge).
Since pinctrl is an infrastructure module, its resume should be issued
prior to other IO drivers. The pinctrl PM operations are requested at
early/late stages for this reason.

This patch adds the gpio-ranges and gpio-reserved-ranges property
definitions to the binding text files supported by the pinctrl-msm
driver framework.
gpio-ranges:
For DT-based platforms the pinctrl-msm framework currently relies
on the deprecated-for-DT gpiochip_add_pin_range() function to add
the range of GPIOs to be handled by the pin controller. Due to
interactions within gpiolib code, this causes the pinctrl-msm
driver to bail out (-517) during boot when a gpio-hog is declared.
This can be fatal and cause the system to not boot or reset
(for a detailed explanation and call-trace, refer to patch:
"pinctrl: msm: fix gpio-hog related boot issues" in this series).
gpio-reserved-ranges:
The binding has been added as a precaution since the TrustZone
firmware (aka QSEE), which is running as the hypervisor, might
have reserved certain, but undisclosed pins. Hence reading or
writing to the registers for those pins will cause an
XPU violation and this subsequently crashes the kernel.

Apart from the usual stuff, the debugfs code is currently also used for
one non-obvious side effect. It attempts to check whether the chip's
registers are still set to an expected value, and if not, re-initializes
them. It seems that the driver has "always" done so.
The code, however, also checks the INTF register which normally
indicates which pins have caused the recent interrupt. That's a volatile
register, and the datasheet says that writes are ignored in there.
When I'm just cat-ing /sys/kernel/debug/gpio with no SPI traffic and no
nosie on the GPIO lines, I'm not getting any warnings. Once I actually
use these GPIOs and cat that file in parallel, I always seem to get a:
mcp23s08 spi1.1: restoring reg 0x07 from 0x0000 to 0xffff (power-loss?)
This might be a sign that I should not leave my unused inputs floating,
but the code should not be checking a volatile register, anyway. Let's
simply skip this last item in the iteration. I was also considering
removing this enitre re-initialization because it's non-obvious, but the
code survived various refactorings already and has sign-offs by people
who know more than I do, so let's leave it as-is. For now :).

This tag contains some small RISC-V updates I'd like to target for 4.18.
They are all fairly small this time. Here's a short summary, there's
more info in the commits/merges.
* A fix to __clear_user to respect the passed arguments.
* Enough support for the perf subsystem to work with RISC-V's ISA
defined performance counters.
* Support for sparse and cleanups suggested by it.
* Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
* Some MAINTAINERS cleanups.
* The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
present.
I've given these a simple build+boot test.
