c007b3a697 ARM: dts: imx6qdl: don't configure reserved pad settings
Several dts files set a bit in the SPEED field for pads
RGMII_{R,T}{XC,D0,D1,D2,D3,X_CTL}, but that doesn't exist. Writing there
doesn't have an effect and the bit reads as zero.

f1472f82cc ARM: dts: imx6qdl-sabresd: Pass the correct PCI reset polarity
The PCI reset GPIO is active low, so represent it with the
GPIO_ACTIVE_LOW flag.

Even though the imx6 PCI driver will not take the polarity into account
in this case, it is better to provide a correct description in device-tree.

5d6253750f ARM: dts: imx: Add basic dts support for imx6qp SOC
The i.MX6Quad Plus processor is an high performance SOC of i.MX6 family.
It has enhanced graphics performance and increased overall memory bandwidth
compared to i.MX6Q. Most of the design are same as i.MX6Quad/Dual, so code
for i.MX6Quad can be resued by this chip. The revision number is identied as
i.MX6Q Rev2.0, but actually it is a new chip, as we did many change to the
overall architecture.

This patch adds basic dtsi file support for the new i.MX6Quad Plus processor.

26cefdd15d ARM: dts: imx: replace legacy wakeup property with 'wakeup-source'
Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux,wakeup" and "enable-sdio-wakeup" boolean
property to enable the wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

b3a5af435a ARM: DT updates for v4.3
This is the usual large batch of DT updates. Lots and lots of smaller
 changes, some of the larger ones to point out are:
 
 - 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.

d28be499c4 ARM: dts: imx6qdl-sabresd: Allow HDMI and LVDS to work simultaneously
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

With this change the LDB pixel clock goes to 68.57 MHz, which is still
within the valid range for the HSD100PXN1 LVDS panel.

6da314122d ARM: SoC DT updates for 3.19
The DT branch adds a lot of new stuff for additional SoC and board
 support. The branch is the largest one and contains 513 out of the
 total 972 non-merge arm-soc changesets for 3.19.
 
 Most of the changes are about enabling additional on-chip devices for
 existing machines, but there are also an unusual number of new SoC
 types being added this time:
 
 * AMLogic Meson8
 * ARM Realview in DT mode
 * Allwinner A80
 * Broadcom BCM47081

 * Freescale Vybrid 500 series
 * Mediatek MT6592, MT8127, MT8135
 * STMicroelectronics STiH410
 * Samsung Exynos4415
 
 The level of support for the above differs widely, some are just
 stubs with nothing more than CPU, memory and a UART, but others
 are fairly complete. As usual, these get extended over time.

 list of model strings that are showing up in new dts files:

 * Buffalo WZR-1750DHP (BCM4708)

 * D-Link DIR-665
 * Google Spring
 * IGEP COM MODULE Rev. G (TI OMAP AM/DM37x)

Passing '0x80000000' to the pin configuration means that kernel will skip the
IOMUXC_SW_PAD_CTL configuration and will use whathever values come from the
bootloader.

Instead of relying on the bootloader setup, let's configure it in the kernel to
have predictable settings.

'0x1b0b0' is the default POR value for all these pins and has also been verified
that the pins are using this value by manually inspecting the IOMUXC_SW_PAD_CTL
registers, so no functional change has been made.

77112dd58a ARM: dts: imx: specify the value of audmux pinctrl instead of 0x80000000
We must specify the value of audmux pinctrl if we want to use pinctrl_pm().
Thus change bypass value 0x80000000 to what we exactly need.

This patch also seperately unset PUE bit for TXD so that IOMUX won't pull
up/down the pin after turning into tristate. When we use SSI normal mode to
playback monaural audio via I2S signal, there'd be a pulled curve occur to
its signal at the second slot if setting PUE bit for TXD. And it will make
the second channel to play a constant noise. So by keeping the signal level
in the second slot, we can get a constant high level signal (-1) or a low
level one (0).

817c27a128 ARM: dts: imx6qdl: make pinctrl nodes board specific
Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts.  However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected.  This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board.  It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.

The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral.  Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

c56009b2f6 ARM: dts: imx: share pad macro names between imx6q and imx6dl
The imx6q and imx6dl are two pin-to-pin compatible SoCs.  The same board
design can work with either chip plugged into the socket, e.g. sabresd
and sabreauto boards.

We currently define pin groups in imx6q.dtsi and imx6dl.dtsi
respectively because the pad macro names are different between two
chips.  This brings a maintenance burden on having the same label point
to the same pin group defined in two places.

The patch replaces prefix MX6Q_ and MX6DL_ with MX6QDL_ for both SoCs
pad macro names.  Then the pin groups becomes completely common between
imx6q and imx6dl and can just be moved into imx6qdl.dtsi, so that the
long term maintenance of imx6q/dt pin settings becomes easier.

Unfortunately, the change brings some dramatic diff stat, but it's all
about DTS file, and the ultimate net diff stat is good.
