Pull char/misc driver updates from Greg KH:
"Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level hardware
bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of the
crazy out-of-tree drivers that have been floating around for years,
combined with some really hacky userspace implementations. This is
only for GNSS receivers, but you have to start somewhere, and this
is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and
existing drivers.
All of these have been in linux-next for a while with no reported
issues"

Add the QCOM RPMh regulator driver to manage PMIC regulators
which are controlled via RPMh on some Qualcomm Technologies, Inc.
SoCs. RPMh is a hardware block which contains several
accelerators which are used to manage various hardware resources
that are shared between the processors of the SoC. The final
hardware state of a regulator is determined within RPMh by
performing max aggregation of the requests made by all of the
processors.
Add support for PMIC regulator control via the voltage regulator
manager (VRM) and oscillator buffer (XOB) RPMh accelerators.
VRM supports manipulation of enable state, voltage, and mode.
XOB supports manipulation of enable state.

MFD part for bd71837 was changed during the review. Clean regulator part to
match changed MFD:
- renamed header file => fix include
- remove unused platdata as also type definition was removed
- Kconfig option for MFD part was changed => fix depends on clause
- Rename Kconfig option for regulators
As Kconfig option for regulators gets now used (when dependency to MFD is
satisfied) change it so that it won't require new change when support for
bd71847 is added.

Add enable/disable support for switch regulators on pfuze100.
Based on commit 5fe156f1ca ("regulator: pfuze100: add enable/disable for
switch") which is reverted due to boot regressions by commit 464a5686e6
("regulator: Revert "regulator: pfuze100: add enable/disable for switch"").
Disabling the switch regulators will only be done if the user specifies
"fsl,pfuze-support-disable-sw" in its device tree to keep backward
compatibility with current dtb's [1].

For of_find_node_by_name(), you typically pass what the previous call
returned. Therefore, of_find_node_by_name() increases the refcount of
the returned node, and decreases the refcount of the node passed as the
first argument.
of_find_node_by_name() is incorrectly used, and produces a warning.
Fix the warning by using the more suitable function
of_get_child_by_name().
Also add a missing of_node_put() for the returned value, since this was
previously being leaked.

Extend the existing support for backup mode to toggle power switches.
With a toggle power switch (or level signal), the following steps must
be followed exactly:
1. Configure PMIC for backup mode, to change the role of the
accessory power switch from a power switch to a wake-up switch,
2. Switch accessory power switch off, to prepare for system suspend,
which is a manual step not controlled by software,
3. Suspend system,
4. Switch accessory power switch on, to resume the system.
Hence the PMIC is configured for backup mode when "on" or "1" is written
to the PMIC's "backup_mode" virtual file in sysfs. Conversely, writing
"off" or "0" reverts the role of the accessory switch to a power
switch.
Unlike with momentary switches, backup mode is not enabled by default,
as enabling it prevents the board from being powered off using the power
switch, which may confuse the user.

Currently the BD9571MWV PMIC driver uses the standard "wake_up" sysfs
file to control enablement of DDR Backup Mode.
However, configuring DDR Backup Mode is not really equivalent to
configuring the PMIC as a wake-up source. To avoid confusion, use a
custom "backup_mode" attribute file in sysfs instead.

The current code generates a static cehcker warnings because "rid < 0"
is always false:
drivers/regulator/max8997-regulator.c:169 max8997_list_voltage()
warn: condition is always false
The problem is that because of type promotion, if "rid" is negative the
comparison against ARRAY_SIZE() is type promoted to size_t and it's
treated as a very high positive value. I've changed the order of the
checks so now everyone is happy.
