a1d4ef1adf pinctrl: stm32: fix optional IRQ support to gpios
To act as an interrupt controller, a gpio bank relies on the
"interrupt-parent" of the pin controller.
When this optional "interrupt-parent" misses, do not create any IRQ domain.

This fixes a "NULL pointer in stm32_gpio_domain_alloc()" kernel crash when
the interrupt-parent = <exti> property is not declared in the Device Tree.

Update lpass lpi pin control driver, with clock optional check for ADSP
disabled platforms. This check required for distingushing ADSP based
platforms and ADSP bypass platforms.
In case of ADSP enabled platforms, where audio is routed through ADSP
macro and decodec GDSC Switches are triggered as clocks by pinctrl
driver and ADSP firmware controls them. So It's mandatory to enable
them in ADSP based solutions.
In case of ADSP bypass platforms clock voting is optional as these macro
and dcodec GDSC switches are maintained as power domains and operated from
lpass clock drivers.

None of the sunxi pin controllers have a module reset line. All of the
SoC documentation, where available, agrees. The bits that would be used
for the PIO reset (i.e. matching the order of the clock gate bits) are
always reserved, both in the CCU and in the PRCM. And experiments on
several SoCs, including the A33, confirm that those reserved bits indeed
have no effect.

Let's remove this superfluous code and dependency, and also remove the
include statement that was copied to the other r_pio drivers.

fcfde8a7cf Updates for interrupt core and drivers:
Core code:
 
     - Make the managed interrupts more robust by shutting them down in the
       core code when the assigned affinity mask does not contain online
       CPUs.
 
     - Make the irq simulator chip work on RT
 
     - A small set of cpumask and power manageent cleanups
 
   Drivers:
 
     - A set of changes which mark GPIO interrupt chips immutable to prevent
       the GPIO subsystem from modifying it under the hood. This provides
       the necessary infrastructure and converts a set of GPIO and pinctrl
       drivers over.
 
     - A set of changes to make the pseudo-NMI handling for GICv3 more
       robust: a missing barrier and consistent handling of the priority
       mask.
 
     - Another set of GICv3 improvements and fixes, but nothing outstanding
 
     - The usual set of improvements and cleanups all over the place
 
     - No new irqchip drivers and not even a new device tree binding!
       100+ interrupt chips are truly enough.

68aa84ff28 pinctrl: cherryview: Use GPIO chip pointer in chv_gpio_irq_mask_unmask()
The callers already have dereferenced pointer to GPIO chip, no need to
do it again in chv_gpio_irq_mask_unmask(). Hence, replace IRQ data pointer
by GPIO chip pointer.

180f9db775 pinctrl: lynxpoint: make irq_chip immutable
Since recently, the kernel is nagging about mutable irq_chips:

   "not an immutable chip, please consider fixing it!"

Drop the unneeded copy, flag it as IRQCHIP_IMMUTABLE, add the new
helper functions and call the appropriate gpiolib functions.

While at it, switch hwirq variable to use the correct type for
the sake of consistency.

8b3dd882bf pinctrl: stm32: Unshadow np variable in stm32_pctl_probe()
The np variable is used globally for stm32_pctl_probe() and in one of
its code branches. cppcheck is not happy with that:

  pinctrl-stm32.c:1530:23: warning: Local variable 'np' shadows outer variable [shadowVariable]

Instead of simply renaming one of the variables convert some code to
use a device pointer directly.

fa8785e593 pinctrl: sunxi: fix f1c100s uart2 function
Change suniv f1c100s pinctrl,PD14 multiplexing function lvds1 to uart2

When the pin PD13 and PD14 is setting up to uart2 function in dts,
there's an error occurred:
1c20800.pinctrl: unsupported function uart2 on pin PD14

Because 'uart2' is not any one multiplexing option of PD14,
and pinctrl don't know how to configure it.

So change the pin PD14 lvds1 function to uart2.
