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 Freescale i.MX8MN (Freescale is now a
product line of NXP).

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

In current driver, SET_LATE_SYSTEM_SLEEP_PM_OPS is used to install the
callbacks for suspend/resume.
GPIO pin may be used as the interrupt pin by some device. However, using
SET_LATE_SYSTEM_SLEEP_PM_OPS() to install the callbacks, the resume
callback is called after resume_device_irqs(). Unintended interrupts may
arrive due to resuming device irqs first, but the GPIO controller is not
properly restored.
Normally, for a SMP system, there are multiple cores, so even when there are
unintended interrupts, BSP gets the chance to initialize the GPIO chip soon.
But when there is only 1 core is active (other cores are offlined or
single core) during resume, it is more easily to observe the unintended
interrupts.
This patch renames the suspend/resume function by adding suffix "_noirq",
and installs the callbacks using SET_NOIRQ_SYSTEM_SLEEP_PM_OPS().

Clearing the GPIO_EN bit from chv_gpio_disable_free is a bad idea and
pinctrl-cherryview.c is the only Intel pinctrl driver doing something
like this.
Clearing the GPIO_EN bit means that if the pin was an output it is now
effectively floating. The datasheet is not clear what happens to pull ups /
downs in this case, but from testing it looks like these are disabled too,
also floating input pins.
One example where this is causing issues is the soc_button_array input
driver, this parses ACPI tables to create 2 platform devices for the
gpio_keys input driver. The list of GPIOs is passed through struct
gpio_keys_platform_data which uses gpio numbers rather then gpio_desc
pointers.
The buttons handled by this drivers short the pin to ground when pressed
and the volume buttons rely on the SoC's internal pull-up to pull the
pin high when the button is not pressed.
To get the gpio number, the soc_button_array code calls gpiod_get_index
followed by a desc_to_gpio call and then gpiod_put on the gpio_desc.
This last call causes chv_gpio_disable_free to clear the GPIO_EN bit.
When the gpio_keys driver then loads next it gets the gpio_desc again
causing the GPIO_EN bit to be set again and immediately reads the GPIO
value which for the volume buttons reads 0 at this time, causing a spurious
press of the volume buttons to get reported.
Putting a small delay between the gpio_desc request and the read fixes
this, I assume that this is caused by the pull-up being temporarily
disabled while the GPIO_EN bit is cleared as the powerbutton which also
has its GPIO_EN bit cleared does not have this problem.
The soc_button_array code is not the only code temporarily requesting GPIOs
the DWC3 PCI code also does this, to set the enable and reset GPIOs for the
external phy, so that the code instantiating the ULPI phy can read the
vendor and product ID registers from the phy. These GPIOs are released
after this so that the PHY driver can claim and use them when it loads.
Another example of temporary GPIO usage would be a user-space set_gpio
utility using the userspace ioctls to set a GPIO as output value 0 or 1,
having the GPIO revert to floating as soon as this utility exits would
certainly be unexpected behavior.
One argument in favor of clearing the GPIO_EN bit is if the GPIO is going
to be muxed to another function after being released, but in that case
chv_pinmux_set_mux() already clears it.
TL;DR: Clearing the GPIO_EN bit from is a bad idea, this commit therefor
removes the clearing from chv_gpio_disable_free(), replacing it with code
to clear the interrupt-trigger condition so that the GPIO stops generating
interrupts when released, as pinctrl-baytrail.c does.
Note this commit adds a !chv_pad_locked() condition to the trigger clearing
call, which the original GPIO_EN clearing code was missing.

Merge tag 'v4.19-rc6' into devel
This is the 4.19-rc6 release
I needed to merge this in because of extensive conflicts in

This reverts commit 55aedef50d.
Commit 55aedef50d ("pinctrl: intel: Do pin translation when lock IRQ")
added special translation from GPIO number to hardware pin number to
irq_reqres/relres hooks to avoid failure when IRQs are requested. The
actual failure happened inside gpiochip_lock_as_irq() because it calls
gpiod_get_direction() and pinctrl-intel.c::intel_gpio_get_direction()
implementation originally missed the translation so the two hooks made
it work by skipping the ->get_direction() call entirely (it overwrote
the default GPIOLIB provided functions).
The proper fix that adds translation to GPIO callbacks was merged with
commit 96147db1e1 ("pinctrl: intel: Do pin translation in other GPIO
operations as well"). This allows us to use the default GPIOLIB provided
functions again.
In addition as find out by Benjamin Tissoires the two functions
(intel_gpio_irq_reqres()/intel_gpio_irq_relres()) now cause problems of
their own because they operate on pin numbers and pass that pin number
to gpiochip_lock_as_irq() which actually expects a GPIO number.

It turns out the HOSTSW_OWN register offset is different between LP and
H variants. The latter should use 0xc0 instead so fix that.

mrfld_read_bufcfg() helper checks if pin is correct and reads back
the current value of corresponding BUFCFG register.
While it adds lines of code it will be easier to maintain in the future.

For some reason I thought GPIOLIB handles translation from GPIO ranges
to pinctrl pins but it turns out not to be the case. This means that
when GPIOs operations are performed for a pin controller having a custom
GPIO base such as Cannon Lake and Ice Lake incorrect pin number gets
used internally.
Fix this in the same way we did for lock/unlock IRQ operations and
translate the GPIO number to pin before using it.

There is no need to include linux/init.h when at the same time
we include linux/module.h.
Remove redundant inclusion.
While here, sort header block alphabetically for easy maintenance.
