Sorry - got Linus W's email address wrong in first send.
v4 changes:
Changed as requested by Stephen Warren:
Corrected the range checking in of_property_read_u32_index().
Fix configs[0] assignment in wmt_pctl_dt_node_to_map_pull().
Remove the kfree(maps) call, and use devm_kzalloc to simplify the fail path.
Drop the custom .of_xlate function and use the default of_gpio_simple_xlate.
Move the platform memory mapping from per-soc to common init.
v3 changes:
Rebased onto v3.9-rc4
Added the missing interrupt-controller info to the relevant dtsi files.
Removed the gpio-vt8500.txt binding along with the gpio driver.
Changes made as requested by Linux Walleij:
Removed the wm,pinmux property which has caused too much confusion, and left the
open-coded version in arm/arch-vt8500/vt8500.c until a proper solution
is sorted out.
Changes made as requested by Stephen Warren:
Defined an active-low flag for gpio since its useful and we will have a use-case
for it with our LCD power-on/off.
v2 changes:
Rebased onto v3.9-rc2
Changes made as requested by Linus Walleij:
Moved the files into drivers/pinctrl/vt8500/ to keep them tidy.
Changed readl/writel to *_relaxed variants.
Comment indentation corrected and remove additional whitespace.
Changed wmt_pctl_find_group_by_pin() error code from -1 to -EINVAL.
Removed OF read indexed-u32 function to OF subsystem.
General code tidy up as requested.
Changes made as requested by Stephen Warren:
Add binding information for interrupt generation.
Move optional properties to correct location in document.
This patch series removes the existing GPIO driver and replaces it with
a combined pinctrl+gpio driver.
Patch 1 - Add an OF function to read the nth u32 value from a property
listing multiple values.
Patch 2 - Increase the available GPIO space for the newly added gpios.
Because there is no hardware documentation from Wondermedia we don't know
how many GPIO's there actually are. New gpio pins have been located since
the original GPIO driver was written, hence the increase.
Patch 3 - The main pinctrl/gpio driver and the data for the 5 supported SoCs.
Each SoC is different, and therefore has its own data. This design was
borrowed from the Tegra pinctrl driver. The pin numbering is based on a
bank+pin encoding so that when other pin functions are found later on we can
add them without having to renumber existing pins.
Patch 4 - Update the SoC dts(i) files to support the new pinctrl driver.
Patch 5 - Remove the existing GPIO driver nodes from the dtsi's.
Patch 6 - Remove the existing GPIO driver.
I suspect this series may need to be broken up since there are two arm-soc
patches, and 4 pinctrl/gpio patches.
Patch 1 is required for the new driver to function properly.
Patch 2 is independant, but required for the driver to function properly.
Patches 3-4 are pinctrl/gpio patches.
Patch 5-6 remove the old gpio code which is no longer required.
Patch 2 could go via arm-soc if necessary.

With the inclusion of the pin control driver, more GPIO pins have been
identified on the arch-vt8500 SoCs requiring an increase in the available
GPIOs.

1.7.9.5
This patch adds support for the GPIO/pinmux controller found on the VIA
VT8500 and Wondermedia WM8xxx-series SoCs.
Each pin within the controller is capable of operating as a GPIO or as
an alternate function. The pins are numbered according to their control
bank/bit so that if new pins are added, the existing numbering is maintained.
All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and
WM8850.

+VIA VT8500 and Wondermedia WM8xxx-series pinmux/gpio controller
+
+These SoCs contain a combined Pinmux/GPIO module. Each pin may operate as
+either a GPIO in, GPIO out or as an alternate function (I2C, SPI etc).
+
+Required properties:
+- compatible: "via,vt8500-pinctrl", "wm,wm8505-pinctrl", "wm,wm8650-pinctrl",
+ "wm8750-pinctrl" or "wm,wm8850-pinctrl"
+- reg: Should contain the physical address of the module's registers.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters.
+ bit 0 - active low
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO 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".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux functions to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pull parameter implies no information about the mux function.
+
+Required subnode-properties:
+- wm,pins: An array of cells. Each cell contains the ID of a pin.
+
+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alternate
+
+- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of wm,function and wm,pull may contain either a single value which
+will be applied to all pins in wm,pins, or one value for each entry in
+wm,pins.
+
+Example:
+
+ pinctrl: pinctrl {
+ compatible = "wm,wm8505-pinctrl";
+ reg = <0xD8110000 0x10000>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };

-Required properties:
-- compatible : "via,vt8500-gpio", "wm,wm8505-gpio"
- or "wm,wm8650-gpio" depending on your SoC
-- reg : Should contain 1 register range (address and length)
-- #gpio-cells : should be <3>.
- 1) bank
- 2) pin number
- 3) flags - should be 0
-
-Example:
-
- gpio: gpio-controller@d8110000 {
- compatible = "via,vt8500-gpio";
- gpio-controller;
- reg = <0xd8110000 0x10000>;
- #gpio-cells = <3>;
- };
-
- vibrate {
- gpios = <&gpio 0 1 0>; /* Bank 0, Pin 1, No flags */

Those changes all look fine.

I'm not sure that's a good idea.
The issue is that dt_node_to_maps() is called every time a pinctrl
consumer is probed, whereas the devm_kzalloc() call in dt_node_to_maps()
uses the pinctrl device itself, not the pinctrl consumer device.. Each
client's probe() could be deferred a few times. Hence, you may end up
accumulating all those map entries from the deferred probes, until the
pinctrl driver itself is remove()d. Similarly, if you unload/load a
(pinctrl client) driver module over and over, the same thing will happen.
Oh, and you left the following in there too:
