pinctrl: qcom: msm8974: Add hsic_ctl pinmux
The msm8974 pinctrl variant has a couple USB HSIC "glue"
registers that let us mux between the pinctrl register settings
or the HSIC core settings for the HSIC pins (gpio 144 and gpio
145). Support this method of operation by adding hsic_data and
hsic_strobe pins that can select between hsic_ctl and gpio
functions. This allows us to toggle the hsic pin configuration
over to the HSIC core at runtime.

pinctrl: imx1: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/pinctrl/freescale/Kconfig:config PINCTRL_IMX1
drivers/pinctrl/freescale/Kconfig: bool "IMX1 pinctrl driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

pinctrl: OF: Don't create a pinctrl handle if no pinctrl entries exist
When pinctrl_get() is called for a device, it will return a valid handle
even if the device itself has no pinctrl state entries defined in
device-tree. This is caused by the function pinctrl_dt_to_map() which
will return success even if the first pinctrl state, 'pinctrl-0', is not
found in the device-tree node for a device.
According to the pinctrl device-tree binding documentation, pinctrl
states must be numbered starting from 0 and so 'pinctrl-0' should always
be present if a device uses pinctrl and therefore, if 'pinctrl-0' is not
present it seems valid that we should not return a valid pinctrl handle.
Fix this by returning an error code if the property 'pinctrl-0' is not
present for a device.

The handle_irq_event_* functions (and I suppose generic_handle_irq()) is
expected to be called with interrupts disabled and they rightfully complain
here because we run in thread context with interrupts enabled.
Fix this by adding IRQF_NO_THREAD flag when the master interrupt is
requested. This prevents forced threading of the interrupt used by the GPIO
host controllers.

The reason why this happens is because intel_gpio_irq_ack() is called with

might_sleep() to trigger.
Fix this by converting the normal spinlock to a raw_spinlock.

pinctrl: uniphier: introduce capability flag
The core part of the UniPhier pinctrl driver needs to support a new
capability for upcoming UniPhier ARMv8 SoCs. This sometimes happens
because pinctrl drivers include really SoC-specific stuff.
This commit intends to tidy up SoC-specific parameters of the existing
drivers before adding the new one. Having just one flag would be
better than adding a new struct member every time a new SoC-specific
capability comes up.
At this time, there is one flag, UNIPHIER_PINCTRL_CAPS_DBGMUX_SEPARATE.
This capability (I'd say rather quirk) was added for PH1-Pro4 and
PH1-Pro5 as requirement from a customer. For those SoCs, one pin-mux
setting is controlled by the combination of two separate registers; the
LSB bits at register offset (8 * N) and the MSB bits at (8 * N + 4).
Because it is impossible to update two separate registers atomically,
the LOAD_PINCTRL register should be set in order to make the pin-mux
settings really effective.

pinctrl: imx: fix initialization of imx_pinctrl_desc
To i.MX7D, there are two iomux controllers, iomuxc and iomuxc_lpsr.
They should not share one pin controller descriptor, otherwise
the value filled into imx_pinctrl_desc when probing the first
iomux controller will be overridden when probing the second one.
In this patch, discard the static allcoated imx_pinctrl_desc and
switch to dynamically allcate pin controller descriptor for each
iomux controller.
