Rob Herring 57a83c5222 ARM: dts: sun9i: Fix I2C bus warnings
dtc has new checks for I2C buses. The sun9i-a80 dts file has a node named
'i2c' which causes a false positive warning. As the node is a RSB bus,
correct the node name to be 'rsb' to fix the warnings.

ARM: dts: sun9i: Add device nodes for documented display pipelines for A80
The Allwinner A80 SoC has 3 display pipelines, of which some parts are
documented:

  - 3x display front ends (FE), documented
  - 2x display enhancement units (DEU), undocumented
  - 3x display back ends (BE), documented
  - 2x dynamic range controller (DRC), undocumented
  - 2x LCDC/TCONs, documented
  - 1x LCDC/TCON, undocumented, and probably not useable
  - 1x HDMI transmitter, undocumented but DesignWare compatible
  - 1x MERGE block, function unknown

This patch adds device nodes for the first 2 documented pipelines:

    FE0 - DEU0 - - BE0 - DRC0 - TCON0
		x
    FE1 - DEU1 - - BE1 - DRC1 - TCON1

Chen-Yu Tsai 651f97f58b ARM: dts: sun9i: Add enable-method for SMP support for the A80 SoC
Using the enable-method property for SMP support would allow future PSCI
implementations to override any in-OS support. This is better than just
matching against the machine compatible, and then having to determine
whether other methods are available or not.

This adds enable-method properties to all CPU nodes.

Chen-Yu Tsai 43f624aa4f ARM: dts: sun9i: Add secure SRAM node used for SMP hotplug
The A80 stores some magic flags in a portion of the secure SRAM. The
BROM jumps directly to the software entry point set by the SMP code
if the flags are set. This is required for CPU0 hotplugging.

CPUCFG for SMP bringup and CPU hotplugging.

CPUCFG is a collection of registers that are mapped to the SoC's signals
from each individual processor core and associated peripherals, such as
resets for processors, L1/L2 cache and other things.

These registers are used for SMP bringup and CPU hotplugging.

Marc Zyngier 387720c938 ARM: DTS: Fix register map for virt-capable GIC
Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

actually support no bias on the pins. During the transition some boards
experienced regular MMC time-outs during normal operation, while others
completely failed to initialize the SD card.

Given that MMC starts in open-drain mode and the pull-ups are required,

Chen-Yu Tsai 67e1cbfbc1 ARM: dts: sun9i: Add NMI controller device node
The Allwinner A80 SoC has an NMI controller. NMI is an external
interrupt pin exclusely used with PMICs and other system critical
peripherals (such as RTC) in Allwinner's reference designs.

Chen-Yu Tsai ed473ebd9c ARM: dts: sun9i: Add Reduced Serial Bus controller device node to A80 dtsi
This patch adds a device node for the Reduced Serial Bus (RSB)
controller and the defacto pinmux setting to the A80 dtsi.

Since there is only one possible pinmux setting for RSB, just
set it in the dtsi.

Linus Torvalds a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.
