6bdafceac1 dt-bindings: pinctrl: qcom: Define common TLMM binding 
Several properties are shared between all TLMM bindings. By providing a
common binding to define these properties each platform's binding can be
reduced to just listing which of these properties should be checked for
- or further specified.

1f306ecbe0 pinctrl: samsung: use raw_spinlock for locking 
This patch converts spin_[lock|unlock] functions of pin bank to
raw_spinlock to support preempt-rt. This can avoid BUG() assertion when
irqchip callbacks are triggerred. Spinlocks can be converted rt_mutex
which is preemptible when we apply preempt-rt patches.

According to "Documentation/driver-api/gpio/driver.rst",

"Realtime considerations: a realtime compliant GPIO driver should not
use spinlock_t or any sleepable APIs (like PM runtime) as part of its
irqchip implementation.

- spinlock_t should be replaced with raw_spinlock_t.[1]

1b399bb048 kconfig.h: Add IF_ENABLED() macro 
IF_ENABLED(CONFIG_FOO, ptr) evaluates to (ptr) if CONFIG_FOO is set to 'y'
or 'm', NULL otherwise. The (ptr) argument must be a pointer.

The IF_ENABLED() macro can be very useful to help GCC drop dead code.

For instance, consider the following:

    #ifdef CONFIG_FOO_SUSPEND
    static int foo_suspend(struct device *dev)
    {
       ...
    }
    #endif

    static struct pm_ops foo_ops = {
	#ifdef CONFIG_FOO_SUSPEND
        .suspend = foo_suspend,
	#endif
    };

While this works, the foo_suspend() macro is compiled conditionally,
only when CONFIG_FOO_SUSPEND is set. This is problematic, as there could
be a build bug in this function, we wouldn't have a way to know unless
the config option is set.

An alternative is to declare foo_suspend() always, but mark it as maybe
unused:

    static int __maybe_unused foo_suspend(struct device *dev)
    {
       ...
    }

    static struct pm_ops foo_ops = {
	#ifdef CONFIG_FOO_SUSPEND
        .suspend = foo_suspend,
	#endif
    };

Again, this works, but the __maybe_unused attribute is required to
instruct the compiler that the function may not be referenced anywhere,
and is safe to remove without making a fuss about it. This makes the
programmer responsible for tagging the functions that can be
garbage-collected.

With this patch, it is now possible to write the following:

    static int foo_suspend(struct device *dev)
    {
       ...
    }

    static struct pm_ops foo_ops = {
        .suspend = IF_ENABLED(CONFIG_FOO_SUSPEND, foo_suspend),
    };

The foo_suspend() function will now be automatically dropped by the
compiler, and it does not require any specific attribute.

e127ef2ed0 pinctrl: renesas: Implement unlock register masks 
The V3U SoC has several unlock registers, one per register group. They
reside at offset zero in each 0x200 bytes-sized block.

To avoid adding yet another table to the PFC implementation, this
patch adds the option to specify an address mask instead of the fixed
address in sh_pfc_soc_info::unlock_reg.

6dd169fc20 pinctrl: renesas: checker: Restrict checks to Renesas platforms 
When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin
control driver runs sanity checks against the pin control tables.  This
may cause lots of output on the console, and can be annoying in ARM
multi-platform kernels.  Fix this by only running the checks when
running on SuperH, or on a DT platform supported by the Renesas pin
controller driver.
