pinctrl: at91: Fix error handling while doing gpiochio_irqchip_add
This patch removes a call to panic function when gpiochio_irqchip_add
fails and just returns the error to the calling function.
Same return value is used to handle the error case and adds a lable
to release resources on error.
The error message has been improved to indicate failure to add irqchip
to gpiochip.
This also changes first argument to function at91_gpio_of_irq_setup from
struct device_node to struct platform_device. Because The device_node
argument was anyway not being used. Passed pdev so that on failure dev_err
can use &pdev->dev and log can be associated with proper device.

pinctrl: at91: add drive strength configuration
The SAMA5 and SAM9x5 series both have drive strength
options for the PIOs. This patch adds the ability to set
one of three hardware options for drive strengths of low,
medium or high for the each pin. The actual current output
of the chip based on the setting is defined in the datasheets
and varies per pins separate from banks and with supply
voltage.
This patch adds three new dt-bindings that allow setting the
strength when configuring pins. By default, no change will
be made to the drive strength of a pin from its reset value.
Due to the difference between the register addresses of the
SAMA5 and SAM9x5 series, a new sama5d3-pinctrl id was added.

pinctrl: clean up after enable refactoring
commit 2243a87d90b42eb38bc281957df3e57c712b5e56
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.
However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.

pinctrl: avoid duplicated calling enable_pinmux_setting for a pin
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.

pinctrl/at91: Fix lockup when IRQ on PIOC and PIOD occurs
With commit 80cc3732 (pinctrl/at91: convert driver to use gpiolib irqchip)
gpiochip_set_chained_irqchip is called for PIOC, PIOD and PIOE. The
associated GPIO chip for the IRQ chip is overwritten each time, because
they share the same hard IRQ line.
Thus if an IRQ occurs on PIOC or PIOD, gpio_irq_handler will only check on
PIOE (the assigned GPIO chip) where no event occured. Thus the IRQ will
not be cleared, retriggering the ISR.
Fix that (like done before) by only set the PIOC GPIO chip to the IRQ chip
and walk the list in the irq handler.

pinctrl: Pass all configs to driver on pin_config_set()
When setting pin configuration in the pinctrl framework, pin_config_set() or
pin_config_group_set() is called in a loop to set one configuration at a time
for the specified pin or group.
This patch 1) removes the loop and 2) changes the API to pass the whole pin
config array to the driver. It is now up to the driver to loop through the
configs. This allows the driver to potentially combine configs and reduce the
number of writes to pin config registers.
All c files changed have been build-tested to verify the change compiles and
that the corresponding .o is successfully generated.

pinctrl: at91: choose appropriate handler for level interrupts
The current implementation handle both edge and level interrupts with the
'handle_simple_irq' handler.
Level interrupts are active as long as the pin stays at the configured
level (low or high). In this case we have to use 'handle_level_irq' which
mask the interrupt until the handle has treated it.

arm: Move chained_irq_(enter|exit) to a generic file
These functions have been introduced by commit 10a8c383 (irq: introduce
entry and exit functions for chained handlers) in asm/mach/irq.h. This
patch moves them to linux/irqchip/chained_irq.h so that generic irqchip
drivers do not rely on architecture specific header files.

Drivers: pinctrl: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

drivers/pinctrl/pinctrl-at91.c: convert kfree to devm_kfree
The function at91_dt_node_to_map is ultimately called by the function
pinctrl_get, which is an exported function. Since it is possible that this
function is not called from within a probe function, for safety, the kfree
is converted to a devm_kfree, to both free the data and remove it from the
device in a failure situation.
