e4fdf59bcc ARM: dts: r8a7791: Correct critical CPU temperature
The R-Car M2W hardware manual states that Tc = –40°C to +105°C. The
thermal sensor has an accuracy of ±5°C and there can be a temperature
difference of 1 or 2 degrees between Tjmax and the thermal sensor due
to the location of the latter.

This means that 95°C is a safer value to use.

be5ae56e5f ARM: dts: r8a7791: Add reset control properties
Add properties to describe the reset topology for on-SoC devices:
  - Add the "#reset-cells" property to the CPG/MSSR device node,
  - Add resets and reset-names properties to the various device nodes.

This allows to reset SoC devices using the Reset Controller API.

Note that resets usually match the corresponding module clocks.
Exceptions are:
  - The audio module has resets for the Serial Sound Interfaces only,
  - The display module has only a single reset for all DU channels, but
    adding reset properties for the display is postponed.

12cc7145d4 ARM: dts: r8a7791: update PFC node name to pin-controller
The device trees for Renesas SoCs use either pfc or pin-controller as the
node name for the PFC device. This patch is intended to take a step towards
unifying the node name used as pin-controller which appears to be the more
generic of the two and thus more in keeping with the DT specs.

My analysis is that this is a user-visible change to the extent that kernel
logs, and sysfs entries change from e6060000.pfc and pfc@e6060000 to
e6060000.pin-controller and pin-controller@e6060000.

d49db72b56 ARM: dts: r8a7791: Tidyup Audio-DMAC channel for DVC
Current	Audio-DMAC is assigned "rx" as Audio-DMAC0, "tx" as Audio-DMAC1.
Thus, DVC "tx" should be assigned as Audio-DMAC1, instead of Audio-DMAC0.

Because of this, current platform board (using SRC/DVC/SSI)
Playback/Capture both will use same Audio-DMAC0
(but it depends on audio data path).

First note is that this "rx" and "tx" are from each IP point,
it doesn't mean Playback/Capture.
Second note is that Audio DMAC assigned on DT is only for
Audio-DMAC, Audio-DMAC-peri-peri has no entry.

=> Audio-DMAC
-> Audio-DMAC-peri-peri
-- HW connection

Playback case

	[Mem] => [SRC]--[DVC] -> [SSI]--[Codec]

Capture

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.

   mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
   mvebu, allwinner, broadcom, exynos, zynq
 
 - Continued fixes for W=1 dtc warnings

   products and have served their purpose in the kernel as a template
   for teh newer chips from ST
 
 - The exynos4415 dtsi file is removed as nothing uses it.

5f25f9f52e ARM: dts: r8a7791: Correct SCIFB reg properties to cover all registers
Several SCIFB registers reside outside the reported register ranges.
Fortunately this works (on Linux), due to the PAGE_SIZE granularity of
ioremap().

Extend the sizes from 64 to 0x100 bytes to fix this, like is done on
SH/R-Mobile SoCs.

08344f3b43 ARM: SoC: late DT updates for v4.7
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The Renesas R-Car power domain handling, and the Nvidia Tegra USB
 support both hand notable changes that required changing the DT binding
 in a way that only provides compatibility with old DT blobs on new
 kernels but not vice versa. As a consequence, the DT changes
 are based on top of the driver changes and are now in this branch.
 
 For NXP i.MX and Samsung Exynos, the changes in here depend on
 other changes that got merged through the clk maintainer tree.

8ffe93a5b2 ARM: dts: r8a7791: Add L2 cache-controller node
Add a device node for the L2 cache, and link the CPU nodes to it.

The L2 cache for the Cortex-A15 CPU cores is 1 MiB large (organized as
64 KiB x 16 ways).

cac68a56e3 ARM: dts: r8a7791: enable to use thermal-zone
This patch enables to use thermal-zone on r8a7791.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)

And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifying polling-delay[-passive]
property.

You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reaches to the value.
echo $temp > /sys/class/thermal/thermal_zone0/trip_point_0_temp
