+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+ Usage: required

- * this table translates what's is in the AB8500 specification regarding the

- * ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
- * ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),
- *
- * example :
- *
- * ALTERNATE_FUNCTIONS(13, 4, 3, 4, 0, 1 ,2),
- * means that pin AB8500_PIN_W17 (pin 13) supports 4 mux (default/ALT_A,
- * ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
- * select the mux. ALTA, ALTB and ALTC val indicates values to write in
- * ALTERNATFUNC register. We need to specifies these values as SOC
- * designers didn't apply the same logic on how to select mux in the
- * ABx500 family.
- *
- * As this pins supports at least ALT_B mux, default mux is
- * selected by writing 1 in GPIOSEL bit :
- *
- * | GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
- * default | 1 | 0 | 0
- * alt_A | 0 | 0 | 0
- * alt_B | 0 | 0 | 1
- * alt_C | 0 | 1 | 0
- *
- * ALTERNATE_FUNCTIONS(8, 7, UNUSED, UNUSED),
- * means that pin AB8500_PIN_W18 (pin 8) supports 2 mux, so only GPIOSEL
- * register is used to select the mux. As this pins doesn't support at
- * least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
- *
- * | GPIOSEL bit=7 | alternatfunc bit2= | alternatfunc bit1=
- * default | 0 | 0 | 0
- * alt_A | 1 | 0 | 0

- * this table translates what's is in the AB8505 specification regarding the
- * balls alternate functions (as for DB, default, ALT_A, ALT_B and ALT_C).
- * ALTERNATE_FUNCTIONS(GPIO_NUMBER, GPIOSEL bit, ALTERNATFUNC bit1,
- * ALTERNATEFUNC bit2, ALTA val, ALTB val, ALTC val),
- *
- * example :
- *
- * ALTERNATE_FUNCTIONS(13, 4, 3, 4, 1, 0, 2),
- * means that pin AB8505_PIN_D18 (pin 13) supports 4 mux (default/ALT_A,
- * ALT_B and ALT_C), so GPIOSEL and ALTERNATFUNC registers are used to
- * select the mux. ALTA, ALTB and ALTC val indicates values to write in
- * ALTERNATFUNC register. We need to specifies these values as SOC
- * designers didn't apply the same logic on how to select mux in the
- * ABx500 family.
- *
- * As this pins supports at least ALT_B mux, default mux is
- * selected by writing 1 in GPIOSEL bit :
- *
- * | GPIOSEL bit=4 | alternatfunc bit2=4 | alternatfunc bit1=3
- * default | 1 | 0 | 0
- * alt_A | 0 | 0 | 1
- * alt_B | 0 | 0 | 0
- * alt_C | 0 | 1 | 0
- *
- * ALTERNATE_FUNCTIONS(1, 0, UNUSED, UNUSED),
- * means that pin AB9540_PIN_R4 (pin 1) supports 2 mux, so only GPIOSEL
- * register is used to select the mux. As this pins doesn't support at
- * least ALT_B mux, default mux is by writing 0 in GPIOSEL bit :
- *
- * | GPIOSEL bit=0 | alternatfunc bit2= | alternatfunc bit1=
- * default | 0 | 0 | 0
- * alt_A | 1 | 0 | 0

- *
- * As this pins supports at least ALT_B mux, default mux is
