Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.3 kernel cycle:
Core changes:
- Device links can optionally be added between a pin control producer
and its consumers. This will affect how the system power management
is handled: a pin controller will not suspend before all of its
consumers have been suspended.
This was necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense to make
this default in the long run.
Right now it is opt-in per driver.
- Drive strength can be specified in microamps. With decreases in
silicon technology, milliamps isn't granular enough, let's make it
possible to select drive strengths in microamps.
Right now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a product
line of NXP).
- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in addition to
muxing.
- The Qualcomm drivers can now reserve some GPIOs as taken aside and
not usable for users. This is used in ACPI systems to take out some
GPIO lines used by the BIOS so that noone else (neither kernel nor
userspace) will play with them by mistake and crash the machine.
- A slew of refurbishing around the Aspeed drivers (board management
controllers for servers) in preparation for the new Aspeed AST2600
SoC.
- A slew of improvements over the SH PFC drivers as usual.
- Misc cleanups and fixes"

Some subsystems, such as pinctrl, allow continuing to defer probe
indefinitely. This is useful for devices that depend on resources
provided by devices that are only probed after the init stage.
One example of this can be seen on Tegra, where the DPAUX hardware
contains pinmuxing controls for pins that it shares with an I2C
controller. The I2C controller is typically used for communication
with a monitor over HDMI (DDC). However, other instances of the I2C
controller are used to access system critical components, such as a
PMIC. The I2C controller driver will therefore usually be a builtin
driver, whereas the DPAUX driver is part of the display driver that
is loaded from a module to avoid bloating the kernel image with all
of the DRM/KMS subsystem.
In this particular case the pins used by this I2C/DDC controller
become accessible very late in the boot process. However, since the
controller is only used in conjunction with display, that's not an
issue.
Unfortunately the driver core currently outputs a warning message
when a device fails to get the pinctrl before the end of the init
stage. That can be confusing for the user because it may sound like
an unwanted error occurred, whereas it's really an expected and
harmless situation.
In order to eliminate this warning, this patch allows callers of the
driver_deferred_probe_check_state() helper to specify that they want
to continue deferring probe, regardless of whether we're past the
init stage or not. All of the callers of that function are updated
for the new signature, but only the pinctrl subsystem passes a true
value in the new persist parameter if appropriate.

The ASPEED pinctrl driver implementations make heavy use of macros to
minimise tedium of implementation and maximise the chance that the
compiler will catch errors in defining signal and pin configurations.
While the goal of minimising errors is achieved, it is at the cost of
the complexity of the macros.
Document examples of the expanded form of pin declarations to
demonstrate the operation of the macros.

ASPEED have completely rearranged the System Control Unit register
layout with the AST2600. The existing code took advantage of the fact
that the AST2400 and AST2500 had layouts that were similar enough to
have little impact on the pinmux infrastructure (though there is a wart
with read-modify-write vs write-1-clear semantics of the hardware
strapping registers between the two).
Given that any similarity has been thrown out with the AST2600, separate
out the function applying an expression state to be driver-specific.
With it, extract out the pinmux macro jungle to its own header and
implementation so the pieces can be composed without dependency cycles.

Introduce the irq_enable callback which will be same as irq_unmask
except that it will also clear the status bit before unmask.
This will help in clearing any erroneous interrupts that would
have got latched when the interrupt is not in use.
There may be devices like UART which can use the same gpio line
for data rx as well as a wakeup gpio when in suspend. The data that
was flowing on the line may latch the interrupt and when we enable
the interrupt before going to suspend, this would trigger the
unexpected interrupt. This change helps clearing the interrupt
so that these unexpected interrupts gets cleared.

During suspend/resume, mtk_eint_mask may be called while
wake_mask is active. For example, this happens if a wake-source
with an active interrupt handler wakes the system:
irq/pm.c:irq_pm_check_wakeup would disable the interrupt, so
that it can be handled later on in the resume flow.
However, this may happen before mtk_eint_do_resume is called:
in this case, wake_mask is loaded, and cur_mask is restored
from an older copy, re-enabling the interrupt, and causing
an interrupt storm (especially for level interrupts).
Step by step, for a line that has both wake and interrupt enabled:
1. cur_mask[irq] = 1; wake_mask[irq] = 1; EINT_EN[irq] = 1 (interrupt
enabled at hardware level)
2. System suspends, resumes due to that line (at this stage EINT_EN
== wake_mask)
3. irq_pm_check_wakeup is called, and disables the interrupt =>
EINT_EN[irq] = 0, but we still have cur_mask[irq] = 1
4. mtk_eint_do_resume is called, and restores EINT_EN = cur_mask, so
it reenables EINT_EN[irq] = 1 => interrupt storm as the driver
is not yet ready to handle the interrupt.
This patch fixes the issue in step 3, by recording all mask/unmask
changes in cur_mask. This also avoids the need to read the current
mask in eint_do_suspend, and we can remove mtk_eint_chip_read_mask
function.
The interrupt will be re-enabled properly later on, sometimes after
mtk_eint_do_resume, when the driver is ready to handle it.

Before suspending, mtk-eint would set the interrupt mask to the
one in wake_mask. However, some of these interrupts may not have a
corresponding interrupt handler, or the interrupt may be disabled.
On resume, the eint irq handler would trigger nevertheless,
and irq/pm.c:irq_pm_check_wakeup would be called, which would
try to call irq_disable. However, if the interrupt is not enabled
(irqd_irq_disabled(&desc->irq_data) is true), the call does nothing,
and the interrupt is left enabled in the eint driver.
Especially for level-sensitive interrupts, this will lead to an
interrupt storm on resume.
If we detect that an interrupt is only in wake_mask, but not in
cur_mask, we can just mask it out immediately (as mtk_eint_resume
would do anyway at a later stage in the resume sequence, when
restoring cur_mask).

Currently probing of the mcp23s08 results in an error message
"detected irqchip that is shared with multiple gpiochips:

This is due to the following:
Call to mcp23s08_irqchip_setup() with call hierarchy:

gpiochip_irqchip_add_nested()
gpiochip_irqchip_add_key()

The gpiochip_add_irqchip() returns immediately if there isn't a irqchip
but we added a irqchip due to the previous mcp23s08_irqchip_setup()
call. So it calls gpiochip_set_irq_hooks() a second time.
Fix this by moving the call to devm_gpiochip_add_data before

This patch provides basic support for booting with ACPI instead
of the currently supported Device Tree. When doing so there are a
couple of differences which we need to taken into consideration.
Firstly, the SDM850 ACPI tables omit information pertaining to the
4 reserved GPIOs on the platform. If Linux attempts to touch/
initialise any of these lines, the firmware will restart the
platform.
Secondly, when booting with ACPI, it is expected that the firmware
will set-up things like; Regulators, Clocks, Pin Functions, etc in
their ideal configuration. Thus, the possible Pin Functions
available to this platform are not advertised when providing the
higher GPIOD/Pinctrl APIs with pin information.

When booting MSM based platforms with Device Tree or some ACPI
implementations, it is possible to provide a list of reserved pins
via the 'gpio-reserved-ranges' and 'gpios' properties respectively.
However some ACPI tables are not populated with this information,
thus it has to come from a knowledgable device driver instead.
Here we provide the MSM common driver with additional support to
parse this informtion and correctly populate the widely used
'valid_mask'.
