1e98960372 ARM: dts: imx6: Move nodes which have no reg property out of bus
Move tempmon, ldb and pmu nodes from soc node to root node.

The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

This fixes the following build warnings with W=1:

arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/aips-bus@2000000/tempmon missing or empty reg/ranges property
arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/aips-bus@2000000/ldb missing or empty reg/ranges property
arch/arm/boot/dts/imx6dl-apf6dev.dtb: Warning (simple_bus_reg): Node /soc/pmu missing or empty reg/ranges property

Based on a patch from Simon Horman for r8a7795.dtsi.

e94a2309b0 ARM: dts: imx: name the interrupts for the fec ethernet driver
imx7s/imx7d has the ptp interrupt newly added as well.

For imx7, "int0" is the interrupt for queue 0 and ENET_MII
"int1" is for queue 1
"int2" is for queue 2

For imx6sx, "int0" handles all 3 queues and ENET_MII

And of course, the "pps" interrupt is for the PTP_CLOCK_PPS interrupts
This will help document what each interrupt does.

2539f517ac ARM: dts: imx6qdl: Add video multiplexers, mipi_csi, and their connections
This patch adds the device tree graph connecting the input multiplexers
to the IPU CSIs and the MIPI-CSI2 gasket on i.MX6. The MIPI_IPU
multiplexers are added as children of the iomuxc-gpr syscon device node.
On i.MX6Q/D two two-input multiplexers in front of IPU1 CSI0 and IPU2
CSI1 allow to select between CSI0/1 parallel input pads and the MIPI
CSI-2 virtual channels 0/3.
On i.MX6DL/S two five-input multiplexers in front of IPU1 CSI0 and IPU1
CSI1 allow to select between CSI0/1 parallel input pads and any of the
four MIPI CSI-2 virtual channels.

Changes from Steve Longerbeam:
- Removed some dangling/unused endpoints (ipu2_csi0_from_csi2ipu)
- Renamed the mipi virtual channel endpoint labels, from "mipi_csiX_..."
  to "mipi_vcX...".
- Added input endpoint anchors to the video muxes for the connections
  from parallel sensors.

a971c5545c ARM: dts: imx: Pass 'chosen' and 'memory' nodes
Commit 7f107887d1 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.

Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.

116dad7d43 ARM: dts: imx6: Disable "weim" node in the dtsi files
Commit 1be81ea586 ("ARM: dts: imx6: Add imx-weim parameters to
dtsi's") causes the following probe error when the weim node is not
present on the board dts (such as imx6q-sabresd):

imx-weim 21b8000.weim: Invalid 'ranges' configuration
imx-weim: probe of 21b8000.weim failed with error -22

There is no need to always enable the "weim" node on mx6. Do the same
as in the other i.MX dtsi files where "weim" is disabled and only gets
enabled on a per dts basis.

All the imx6 weim dts users explicitily provide 'status = "okay"', so
this change has no impact on current imx6 weim users.

If a board does not use the weim driver it will not describe its 'ranges'
property, so simply disable the 'weim' node in the imx6 dtsi files to
avoid such probe error message.

f065e9e4ad ARM: dts: imx6qdl: Fix SPDIF regression
Commit 833f2cbf70 ("ARM: dts: imx6: change the core clock of spdif")
changed many more clocks than only the SPDIF core clock as stated in
the commit message.

The MLB clock has been added and this causes SPDIF regression as
reported by Xavi Drudis Ferran and also in this forum post:
https://forum.digikey.com/thread/34240

The MX6Q Reference Manual does not mention that MLB is a clock related
to SPDIF, so change it back to a dummy clock to restore SPDIF
functionality.

Thanks to Ambika for providing the fix at:

The interrupt-parent property is not needed as it is inherited from
the parent bus and in the case of the CAAM node actively points to
the wrong interrupt controller (GIC instead of GPC). This leads to
the CAAM IRQs not getting unmasked at the GPC level, leaving them
unable to wake the CPU from wait mode, potentially impacting
performance of the CAAM unit when CPUidle is enabled.

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...

  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"

1a9fa19095 ARM: imx6: correct i.MX6 PCIe interrupt routing
The PCIe interrupts are also routed through the GPC. This has been
missed from the conversion to stacked IRQ domains as the PCIe
controller uses an explicit interrupt map and thus doesn't inherit
the SoC global interrupt parent.

ac4af82b99 ARM: dts: imx6qdl: move HDMI controller to right location in DT
Currently the HDMI controller is a child device of the AIPS bus in the
DT which is clearly wrong. Move it to the right location.
This introduces no functional change it just aligns the DT representation
with reality.
