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

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.

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*"``

Remove the sky2 ethernet device node from the pcie controller which was
invalid to begin with.
The original intent was to allow the bootloader to populate the MAC via
dt but this requires the PCI bus topology to be complete in dt as well
and as these boards have an expansion connector that topology is dynamic
and can't be represented here.

bc677ff42e81bbf78308a7b66cf7b63b0f5c26b0 adds a device-tree property
to specify that an external watchdog reset is used to reset other
portions of the board and not just the IMX6 SoC.
This adds the property to the proper watchdog as well as the pinmux for
the Gateworks Ventana boards that use this external watchdog reset to
reset the PMIC which will reset all the PMIC power rails and not just
a chip-level IMX6 reset. This helps to work around various system issues
that can cause a hang when coming out of reset.

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be
driven from independent sources.
With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the displays supported by the Ventana boards.

No less than twentythree thousand lines of additions! Just imagine the
joy you will have of using your mainline kernel on newly supported

UniPhier hardware!
For those of you feeling less adventurous, added hardware support on

We've got something for everyone here!

- Rockchip veyron (Chromebook) support, as well as several other new boards
- DRM support on Atmel AT91SAM9N12EK
- USB additions on some Allwinner platforms
- Mediatek MT6580 support
- Freescale i.MX6UL support
- cleanups for Renesas shmobile platforms
- lots of added devices on LPC18xx
- lots of added devices and boards on UniPhier
There's also some dependent code added here, in particular some
branches that are primarily merged through the clock tree"

UHS-I support is available on Ventana boards with micro-SD sockets depending
on the board revision. To support this pinctl states for 100Mhz and 200MHz
must be added as well as pinmux of the VSELECT signal. In order to support
UHS-I the I/O rail of the 4-bit data bus must be switchable between 1.8V
and 3.3V.
By adding the no-1-8-v property, which disables UHS-I support, we allow the
bootloader to be in charge of selecting which boards have this capability
by removing that property if the board model/revision implement the support.
Additionally we will remove NANDF_CS1 here from the nand pinmux group as the
second chip-select is not used on any ventana boards and this is the pad
that is used for SD3_VELECT.

The DAI mode is and should be configured by the sound card driver as
codec and ssi have to be in the right modes to communicate with each
other. It is possible to operate the ssi unit or the codec in master mode,
sometimes even on the same board in different configurations.
With the latest changes in the fsl-ssi driver, the 'fsl,mode' property
is only handled as a fallback property. If the sound card sets the DAI
mode correctly, this fallback configuration is dropped.
