Linus Torvalds 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.

Pull ARM DT updates from Olof Johansson:
 "Ladies and gentlemen, we proudly announce to you the latest branch of
  ARM device tree contents for the mainline kernel.  Come and see, come
  and see!

  No less than twentythree thousand lines of additions! Just imagine the
  joy you will have of using your mainline kernel on newly supported
  hardware such as Rockchip Chromebooks, Freescale i.MX6UL boards or
  UniPhier hardware!

  For those of you feeling less adventurous, added hardware support on
  platforms such as TI DM814x and Gumstix Overo platforms might be more
  of your liking.

  We've got something for everyone here!

  Ahem.  Cough.  So, anyway...

Fabio Estevam 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
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 HSD100PXN1 LVDS panel.

Linus Torvalds 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
 * Broadcom Cygnus
 * Freescale LS1021A
 * 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.
 
 There are also many new boards getting added, this is the
 list of model strings that are showing up in new dts files:
 
 * ARM RealView PB1176
 * Altera SOCFPGA Arria 10
 * Asus RT-N18U (BCM47081)
 * Buffalo WZR-1750DHP (BCM4708)
 * Buffalo WZR-600DHP2 (BCM47081)
 * Cygnus Enterprise Phone (BCM911360_ENTPHN)
 * D-Link DIR-665
 * Google Spring
 * IGEP COM MODULE Rev. G (TI OMAP AM/DM37x)
 * IGEPv2 Rev. F (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.

The DAI mode is and should be configured by the sound card driver as

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.

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).

Shawn Guo 56160e3361 ARM: dts: imx6: use generic node name for fixed regulator
The device tree specification recommends that generic name should be
used for nodes.  So instead of naming those fixed regulator nodes
arbitrarily, let's use the generic name 'regulator@num' for those nodes.

Shawn Guo 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.

The CLKO is widely used by imx6q board designs to clock audio codec.
Since most codecs accept 24 MHz frequency, let's initially set up CLKO
with OSC24M (cko <-- cko2 <-- osc).  Then those board specific CLKO
setup for audio codec can be removed.

The board dts files also need an update on cko reference in codec node.

Shawn Guo 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.
