bbc4c8a531 ARM: dts: imx6qdl-gw*: Remove unnecessary #address-cells/#size-cells
Remove the unnecessary #address-cells/#size-cells to avoid warnings
from W=1 build like this:

arch/arm/boot/dts/imx6qdl-gw52xx.dtsi:33.12-78.4: Warning (avoid_unnecessary_addr_size): /gpio-keys: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

05b0852ec9 ARM: dts: imx6qdl-gw5xxx: correct interrupt flags
GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW  = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
  ACTIVE_LOW  => IRQ_TYPE_LEVEL_LOW

64bf0a0af1 ARM: dts: imx6qdl-gw: add Gateworks System Controller support
Add Gateworks System Controller support to Gateworks Ventana boards:
- add dt bindings for GSC mfd driver and hwmon driver for ADC's and
  fan controllers.
- add dt bindings for gpio-keys driver for push-button and interrupt events

fa28d8212e ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files
The imx-pwm driver supports 3 cells and this is the more flexible setting.
So use it by default and overwrite it back to two for the files that
reference the PWMs with just 2 cells to minimize changes.

This allows to drop explicit setting to 3 cells for the boards that already
depend on this. The boards that are now using 2 cells explicitly can be
converted to 3 individually.

c83bbdc227 ARM: dts: imx6qdl-gw5903: Use new CODEC reset pin name
The correct DT property for specifying a GPIO used for reset
is "reset-gpios", the driver now accepts this name, use it here.

404c0c9314 ARM: dts: imx6qdl: Fix memory node duplication
Boards based on imx6qdl have duplicate memory nodes:
- One coming from the board device tree file: memory@
- One coming from the imx6qdl.dtsi file.

Fix the duplication by removing the memory node from
the imx6qdl.dtsi file and by adding 'device_type = "memory";'
in the board Device Tree.

Converted using the following command:
perl -p0777i -e 's/memory\@10000000 \{\n/memory\@10000000 \{\n\t\tdevice_type = \"memory\";\n/m' `find ./arch/arm/boot/dts -name "imx6*"``

Fix the following warnings from dtc by adding the unit name to memory
nodes:

Warning (unit_address_vs_reg): Node /memory has a reg or ranges property, but no unit name

Converted using the following command:
