Hi Lee, Rob,

I haven't been able to found this patch in -next branches, can one of 
you merge it ?

Thanks,

Rob,

We should agree on a process going forward.  Do you take DT document
changes or should I?  Up until we moved to YAML formatting, I took
them but responsibly seems to have migrated over to you since then.

I don't mind either way.

-- reg: I2C slave address of the device.
-- interrupts: interrupt specifier triggered by MFX_IRQ_OUT signal.
-  Please refer to ../interrupt-controller/interrupt.txt
-
-Optional properties:
-- drive-open-drain: configure MFX_IRQ_OUT as open drain.
-- vdd-supply: phandle of the regulator supplying STMFX.

-
-ST Multi-Function eXpander (STMFX) offers up to 24 GPIOs expansion.
-Please refer to ../mfd/stmfx.txt for STMFX Core bindings.
-
-Required properties:
-- compatible: should be "st,stmfx-0300-pinctrl".
-- #gpio-cells: should be <2>, the first cell is the GPIO number and the second
-  cell is the gpio flags in accordance with <dt-bindings/gpio/gpio.h>.

-- interrupt-controller: marks the device as an interrupt controller.
-- gpio-ranges: specifies the mapping between gpio controller and pin
-  controller pins. Check "Concerning gpio-ranges property" below.
-Please refer to ../gpio/gpio.txt.

-Please refer to pinctrl-bindings.txt for pin configuration.
-
-Required properties for pin configuration sub-nodes:
-- pins: list of pins to which the configuration applies.
-
-Optional properties for pin configuration sub-nodes (pinconf-generic ones):
-- bias-disable: disable any bias on the pin.
-- bias-pull-up: the pin will be pulled up.
-- bias-pull-pin-default: use the pin-default pull state.
-- bias-pull-down: the pin will be pulled down.
-- drive-open-drain: the pin will be driven with open drain.
-- drive-push-pull: the pin will be driven actively high and low.
-- output-high: the pin will be configured as an output driving high level.
-- output-low: the pin will be configured as an output driving low level.
-
-Note that STMFX pins[15:0] are called "gpio[15:0]", and STMFX pins[23:16] are
-called "agpio[7:0]". Example, to refer to pin 18 of STMFX, use "agpio2".
-
-Concerning gpio-ranges property:
-- if all STMFX pins[24:0] are available (no other STMFX function in use), you
-  should use gpio-ranges = <&stmfx_pinctrl 0 0 24>;
-- if agpio[3:0] are not available (STMFX Touchscreen function in use), you

-- if agpio[7:4] are not available (STMFX IDD function in use), you
