Use the bank name as the irqchip name. This name is later visible in
/proc/interrupts, what makes it possible to easily identify each
GPIO interrupt.
/proc/interrupts before this patch:
143: 0 exynos4210_wkup_irq_chip 7 Edge hdmi
144: 0 exynos4210_wkup_irq_chip 6 Level wm8994
145: 1 exynos4210_wkup_irq_chip 7 Edge max77686-pmic, max77686-rtc
146: 1 exynos_gpio_irq_chip 3 Edge 3-0048
/proc/interrupts after this patch:
143: 0 gpx3 7 Edge hdmi
144: 0 gpx3 6 Level wm8994
145: 1 gpx0 7 Edge max77686-pmic, max77686-rtc
146: 1 gpm2 3 Edge 3-0048
Handling of the eint_wake_mask_value has been reworked, because each bank
has now its own exynos_irq_chip structure allocated.

intel-pinctrl for v5.9-1
* New driver for Emmitsburg
* New driver for Tiger Lake-H
* Part 3 of Cherryview driver clean up
* Fix a glitch on Baytrail platforms
The following is an automated git shortlog grouped by driver:
ARM/orion/gpio:
- Make use of for_each_requested_gpio()
at91:
- Make use of for_each_requested_gpio()
baytrail:
- Use fallthrough pseudo-keyword
- Fix pin being driven low for a while on gpiod_get(..., GPIOD_OUT_HIGH)
- Drop no-op ACPI_PTR() call
cherryview:
- Re-use data structures from pinctrl-intel.h (part 3)
- Convert chv_writel() to use chv_padreg()
- Introduce helpers to IO with common registers
- Introduce chv_readl() helper
gpio:
- xra1403: Make use of for_each_requested_gpio()
- mvebu: Make use of for_each_requested_gpio()
gpiolib:
- Introduce for_each_requested_gpio_in_range() macro
intel:
- Add Intel Emmitsburg pin controller support
- Make use of for_each_requested_gpio_in_range()
- Protect IO in few call backs by lock
- Split intel_config_get() to three functions
- Drop the only label in the code for consistency
- Get rid of redundant 'else' in intel_config_set_debounce()
- Make use of IRQ_RETVAL()
- Reduce scope of the lock
- Disable input and output buffer when switching to GPIO
- Allow drivers to define ACPI address space ID
- Allow drivers to define total amount of IRQs per community
lynxpoint:
- Drop no-op ACPI_PTR() call
- Introduce helpers to enable or disable input
- Make use of for_each_requested_gpio()
merrifield:
- Add I²S bus 2 pins to groups and functions
- Update pin names in accordance with official list
tigerlake:
- Add support for Tiger Lake-H
This driver adds pinctrl/GPIO support for Intel Emmitsburg PCH. The
GPIO controller is based on the next generation GPIO hardware but still
compatible with the one supported by the Intel core pinctrl/GPIO driver.

Not all sourcefiles which end up including pinctrl-mtk-common-v2.h make use
of 'mtk_default_register_base_names' and there is nowhere we can place the
definition to void the need for __maybe_unused except its own headerfile,
which seems like overkill. So instead we tell the compiler that it's okay
for it to be unused by some of the consumers.

We need to iterate over each pin in a group for a function and
disable higher priority mux configurations on the pin before finally
muxing the relevant function's signal. With the current debug output it
is hard to track what register output is relevant to which operation, so
break up the actions in the debug output by providing some more context.

Modify omap_gpio_set_config() to handle pin config bias flags by calling
gpiochip_generic_config().
The pin group for the gpio line must have the corresponding pinconf
properties:
PIN_CONFIG_BIAS_PULL_UP requires "pinctrl-single,bias-pullup"
PIN_CONFIG_BIAS_PULL_DOWN requires "pinctrl-single,bias-pulldown"
This is necessary for pcs_pinconf_set() to find the requested bias
parameter in the PIN_MAP_TYPE_CONFIGS_GROUP pinctrl map.
