We have four Qualcomm-related pin control drivers, and now there
are drivers coming in for the PMICs on these systems, so let's
create a qcom subdirectory to hold all the Qualcomm stuff.

This patch extends the range of settings configurable via pinfunc API
to cover pin value as well. This allows configuration of default values
of pins, which is useful for pins that are not supposed to be used by
any dedicated driver, but need certain board-specific setting.

One of remaining limitations of current pinctrl-samsung driver was
the inability to parse multiple pinmux/pinconf group nodes grouped
inside a single device tree node. It made defining groups of pins for
single purpose, but with different parameters very inconvenient.
This patch implements Tegra-like support for grouping multiple pinctrl
groups inside one device tree node, by completely changing the way
pin groups and functions are parsed from device tree. The code creating
pinctrl maps from DT nodes has been borrowed from pinctrl-tegra, while
the initial creation of groups and functions has been completely
rewritten with following assumptions:
- each group consists of just one pin and does not depend on data
from device tree,
- each function is represented by a device tree child node of the
pin controller, which in turn can contain multiple child nodes
for pins that need to have different configuration values.
Device Tree bindings are fully backwards compatible. New functionality
can be used by defining a new pinctrl group consisting of several child
nodes, as on following example:
sd4_bus8: sd4-bus-width8 {
part-1 {
samsung,pins = "gpk0-3", "gpk0-4",
"gpk0-5", "gpk0-6";
samsung,pin-function = <3>;
samsung,pin-pud = <3>;
samsung,pin-drv = <3>;
};
part-2 {
samsung,pins = "gpk1-3", "gpk1-4",
"gpk1-5", "gpk1-6";
samsung,pin-function = <4>;
samsung,pin-pud = <4>;
samsung,pin-drv = <3>;
};
};
Tested on Exynos4210-Trats board and a custom Exynos4212-based one.

Handling of irq_chip operations for GPIO and WKUP external interrupts
is mostly the same, with the difference being offset of registers.
However currently the driver has all the code duplicated for both EINT
types, which is undesirable, because changes in irq_chip operations have
to be done to both instances of the same code.
This patch fixes this by creating exynos_irq_chip struct that has normal
irq_chip struct embedded and contain differences between particular EINT
types, which are three register offsets. One instance of code is removed
and the new structure is used instead to fetch necessary data instead of
samsung_pin_ctrl struct used previously.
While at it, the patch removes Exynos-specific fields from
aforementioned structure to improve layering of the driver.

This patch makes the pinctrl-samsung driver configure GPIO direction on
its own, without using the pinctrl_gpio_direction_*() "helpers". The
rationale behind this change is as follows:
- pinctrl-samsung does not need translation from GPIO namespace to
pinctrl namespace to handle GPIO operations - GPIO chip and offset
therein are enough to calculate necessary offsets and bit masks in
constant time,
- the pinctrl_gpio_direction_*() functions do not do anything useful
other than translating the pin into pinctrl namespace and calling the
.gpio_set_direction() from pinmux_ops of the controller,
- the undesirable side effect of using those helpers is losing the
ability to change GPIO direction in atomic context, because they
explicitly use a mutex for synchronization,
Results of this patch are:
- fixed warnings about scheduling while atomic in code that needs to
set GPIO direction in atomic context (e.g. interrupt handler),
- reduced overhead of bitbanging drivers that use gpio_direction_*(),
e.g. i2c-gpio.

For Baytrail, you should never set a GPIO set to direct_irq
to output mode. When direct_irq_en is set for a GPIO, it is
tied directly to an APIC internally, and making the pad output
does not make any sense. Assert a WARN() in the event this happens.

Upcoming Rockchip SoCs have additional quirks to handle. Currently they would
be handled by giving the bank a special compatible property. But the nature
of the new quirks would require a lot of them. Also as we want to move to the
separate dw_gpio driver in the future, these bank-definitions should be
extended at all.
Describing the bank quirks this way also enables us to deprecate the special
bank compatible string for bank0 on rk3188 and simplify the handling code.

What the patch does:
1. Call pinmux_disable_setting ahead of pinmux_enable_setting
each time pinctrl_select_state is called
2. Remove the HW disable operation in pinmux_disable_setting function.
3. Remove the disable ops in struct pinmux_ops
4. Remove all the disable ops users in current code base.
Notes:
1. Great thanks for the suggestion from Linus, Tony Lindgren and
Stephen Warren and Everyone that shared comments on this patch.
2. The patch also includes comment fixes from Stephen Warren.
The reason why we do this:
1. To avoid duplicated calling of the enable_setting operation
without disabling operation inbetween which will let the pin
descriptor desc->mux_usecount increase monotonously.
2. The HW pin disable operation is not useful for any of the
existing platforms.
And this can be used to avoid the HW glitch after using the
item #1 modification.
In the following case, the issue can be reproduced:
1. There is a driver that need to switch pin state dynamically,
e.g. between "sleep" and "default" state
2. The pin setting configuration in a DTS node may be like this:
component a {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&a_grp_setting &c_grp_setting>;
pinctrl-1 = <&b_grp_setting &c_grp_setting>;
}
The "c_grp_setting" config node is totally identical, maybe like
following one:
c_grp_setting: c_grp_setting {
pinctrl-single,pins = <GPIO48 AF6>;
}
3. When switching the pin state in the following official pinctrl
sequence:
pin = pinctrl_get();
state = pinctrl_lookup_state(wanted_state);
pinctrl_select_state(state);
pinctrl_put();
Test Result:
1. The switch is completed as expected, that is: the device's
pin configuration is changed according to the description in the
"wanted_state" group setting
2. The "desc->mux_usecount" of the corresponding pins in "c_group"
is increased without being decreased, because the "desc" is for
each physical pin while the setting is for each setting node
in the DTS.
Thus, if the "c_grp_setting" in pinctrl-0 is not disabled ahead
of enabling "c_grp_setting" in pinctrl-1, the desc->mux_usecount
will keep increasing without any chance to be decreased.
According to the comments in the original code, only the setting,
in old state but not in new state, will be "disabled" (calling
pinmux_disable_setting), which is correct logic but not intact. We
still need consider case that the setting is in both old state
and new state. We can do this in the following two ways:
1. Avoid to "enable"(calling pinmux_enable_setting) the "same pin
setting" repeatedly
2. "Disable"(calling pinmux_disable_setting) the "same pin setting",
actually two setting instances, ahead of enabling them.
Analysis:
1. The solution #2 is better because it can avoid too much
iteration.
2. If we disable all of the settings in the old state and one of
the setting(s) exist in the new state, the pins mux function
change may happen when some SoC vendors defined the
"pinctrl-single,function-off"
in their DTS file.
old_setting => disabled_setting => new_setting.
3. In the pinmux framework, when a pin state is switched, the
setting in the old state should be marked as "disabled".
Conclusion:
1. To Remove the HW disabling operation to above the glitch mentioned
above.
2. Handle the issue mentioned above by disabling all of the settings
in old state and then enable the all of the settings in new state.

When mapping the interrupts, the gpio_to_irq function did not consider
the bank number of the gpio pin in question, only the offset or the
interrupt number in the bank. As a result, requests for interrupts in
the later banks get mapped to the first bank.
This issue was discovered while enabling mmc on the new sun8i platform.
The tablet I have uses a pin/interrupt from the second bank to do mmc
card detection. Tested on this very device with register inspection and
actual mmc card insertion/removal.

Some drivers use disable_irq / enable_irq and do the work
clearing the source in another thread instead of using a threaded
interrupt handler.
The irqchip used not having irq_disable and irq_enable
callbacks in this case, will lead to unnecessary spurious
interrupts:
On a disable_irq in a chip without a handler for this, the irq
core will remember the disable, but not actually call into the
irqchip. With a level triggered interrupt (where the source has
not been cleared) this will lead to an immediate retrigger, at
which point the irq-core will mask the irq. So having an
irq_disable callback in the irqchip will save us the interrupt
firing a 2nd time for nothing.
Drivers using disable / enable_irq like this, will call
enable_irq when they finally have cleared the interrupt source,
without an enable_irq callback, this will turn into an unmask,
at which point the irq will trigger immediately because when it
was originally acked the level was still high, so the ack was
a nop.
