When flipping the polarity will be generated interrupt under certain
circumstances, but GPIO external signal has not changed.
Then, mask the interrupt before polarity setting, and clear the
unexpected interrupt after trigger type setting completed.
Remove mtk_eint_flip_edge: because mtk_eint_unmask already calls it.

SAMA7G5 supports slew rate configuration. Adapt the driver for this.
For output switching frequencies lower than 50MHz the slew rate needs to
be enabled. Since most of the pins on SAMA7G5 fall into this category
enabled the slew rate by default.

pcs_add_function() fails to set the function name in struct pcs_function
when adding a new function. As a result this line in pcs_set_mux():
dev_dbg(pcs->dev, "enabling %s function%i\n",
func->name, fselector);
prints "(null)" for the function:
pinctrl-single 44e10800.pinmux: enabling (null) function0
pinctrl-single 44e10800.pinmux: enabling (null) function1
pinctrl-single 44e10800.pinmux: enabling (null) function2
pinctrl-single 44e10800.pinmux: enabling (null) function3
With this fix, the output is now:

pinctrl-single 44e10800.pinmux: enabling pinmux-mmc0-pins function1

make it easier to correlate function name to function selector without
having to count the lines in the output.

function 0: pinmux-uart0-pins, groups = [ pinmux-uart0-pins ]
function 1: pinmux-uart1-pins, groups = [ pinmux-uart1-pins ]
function 2: pinmux-uart2-pins, groups = [ pinmux-uart2-pins ]
function 3: pinmux-mmc0-pins, groups = [ pinmux-mmc0-pins ]
function 3: pinmux-mmc1-pins, groups = [ pinmux-mmc1-pins ]

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]

- Add otg function and otg-vbus group.
- Add lcd-8bit, lcd-16bit, lcd-18bit, lcd-generic and lcd-special

that aren't in the lcd-18bit and lcd-generic groups (which breaks
Device Tree in theory, but there is none out there for any JZ4760

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.
