According to Documentation/devicetree/bindings/arm/cpus.yaml, the
"enable-method" property should be a property of the individual CPU
nodes, and not of the parent "cpus" container node.
However, on R-Car Gen2 and RZ/G1 SoCs, the property is tied to the
"cpus" node instead.
Secondary CPU bringup and CPU hot (un)plug work regardless, as
arm_dt_init_cpu_maps() falls back to looking in the "cpus" node.
The cpuidle code does not have such a fallback, so it does not detect
the enable-method. Note that cpuidle does not support the
"renesas,apmu" enable-method yet, so for now this does not make any
difference.

The OPP properties, like "operating-points", should either be present
for all the CPUs of a cluster or none. If these are present only for a
subset of CPUs of a cluster then things will start falling apart as soon
as the CPUs are brought online in a different order. For example, this
will happen because the operating system looks for such properties in
the CPU node it is trying to bring up, so that it can create an OPP
table.
Add such missing properties.
Fix other missing properties (like, clock latency, voltage tolerance,
etc) as well to make it all work.

Add soc node to represent the bus and move all nodes with a base address
into this node. This is consistent with handling of R-Car Gen3, RZ/G1, and
R-Car V2H (R8A77920) SoCs upstream. It is intended to migrate other R-Car
Gen2 SoCs to this scheme.
The ordering is derived from simply moving each node with an address up to
before any nodes without a base address that occur before the soc node. To
improve maintainability follow-up patches will sort subnodes of both the
new soc node and the root node.

0xe61f0000 extend to an offset of 0x10, rather than 0x14 which is the case

Second Round of Renesas ARM Based SoC DT Updates for v4.16
* r8a7745 (RZ/G1E) SoC
- Enable SMP
Fabrizio Castro says "Add DT node for the Advanced Power Management
Unit (APMU), add the second CPU core, and use "renesas,apmu" as
"enable-method"."
* r8a7743 (RZ/G1M) SoC
- Add node for thermal sensor module with thermal-zone support
* r8a7743 (RZ/G1M) and r8a7745 (RZ/G1E) SoCs
- Add:
+ Renesas Core Match Timer (CMT) support
+ Renesas Timer Pulse Unit PWM Controller (TPU) support
+ Renesas PWM Timer Controller (PWM) support
* r8a7743 (RZ/G1M) iW-RainboW-G20D-Qseven and
r8a7745 (RZ/G1E) iW-RainboW-G22D development platforms
- Add sound support
* r8a7743 (RZ/G1M), r8a7745 (RZ/G1E) and r8a7792 (R-Car V2H) SoCs
- Allow DTBs of boards of these SoCs to build without any warnings when
compiled with W=1 using gcc-linaro-5.4.1-2017.05
+ Move nodes which have no reg property out of bus, they don't belong there
+ Also sort sub-nodes of root node to allow for easier maintenance
* r8a7790 (R-Car H2), r8a7791 (R-Car M2-W) and r8a7793 (R-Car M2-N) SoCs
- Correct critical CPU temperature
Chris Paterson says "The current R-Car Gen2 device trees define the CPU
critical temperature as 115°C.
The R-Car hardware manuals state 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.
This value should also apply to r8a7792 but thermal sensor support has
not been added yet."
* r8a7740 (R-Mobile A1) SoC
- Correct TPU register block size
Geert Uytterhoven says "The Timer Pulse Unit has registers that lie
outside the declared register block. Enlarge the register block size to
fix this.
This was probably based on the old platform code, which also assumed a
register block size of 0x100."

Geert Uytterhoeven says "Commits 7d29f509d2cfd807 ("dt-bindings: i2c:
i2c-gpio: Add support for named gpios") and 05c74778858d7d99 ("i2c: gpio:

bindings, and deprecated the more error-prone unnamed variant.
This patch series switches all Renesas boards to the new bindings, and
adds the missing GPIO_OPEN_DRAIN I/O flags, which were implicitly
assumed before..."
... Note that after this series is applied, the i2c-gpio buses are no
longer detected when booting new DTBs on old (v4.14 and older) kernels,
which should not be an issue. Booting old DTBs on new kernels is not
affected."
* Update DTS for CMT DT binding rework

in the various Renesas DTS files sh_cmt clocksource driver for the recent
DT binding rework that was merged in v4.14-rc1 and v4.15-rc1..."
* Add SMP support to r8a7794 (R-Car E2) SoC
Sergei Shtylyov says "Add the device tree node for the Advanced Power
Management Unit (APMU). Use the "enable-method" prop to point out that
the APMU should be used for the SMP support."
* Correct primary compatible value for eeprom
on r7s72100 (RZ/A1H) genmai and r8a7791 (R-Car M2-W) koelsh boards
Geert Uytterhoeven says "The Renesas part numbers of the two-wire serial
interface EEPROMs do not follow the 24Cxx pattern, but the R1EX24xxx
pattern.
Hence change the primary compatible values to the appropriate variant of
"renesas,r1ex24xxx", like is already done on Gose.""
* Move cec_clock to root node on r8a7791 (R-Car M2-W) koelsh board
r8a7791 (R-Car M2-W) koelsh board
* Use R-Car SDHI and Ether Gen1 and 2 fallback compat strings
Use recently posted R-Car SDHI and Ether Gen 1 and 2 fallback
compat strings in the DT of Renesas ARM based SoCs.
* Add IIC cores to dtsi of r8a7745 (RZ/G1E) SoC
* Rework DT architecture for r8a7745 (RZ/G1E) iW-RainboW-G22D development
platform and add serial support.
Fabrizio Castro says "... define a new DT architecture for the
iW-RainboW-G22D SODIMM Development Platform to include the configuration

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.

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.

Link the ARM GIC to the INTC-SYS module clock, and add it to the "always

Note that currently the GIC-400 driver doesn't support module clocks nor

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]
rx ~~~~~~~~~~~~
Capture
[Mem] <= [DVC]--[SRC] <- [SSI]--[Codec]

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.

Pull ARM DT updates from Arnd Bergmann:
"Lots of changes as usual, so I'm trying to be brief here. Most of the
new hardware support has the respective driver changes merged through
other trees or has had it available for a while, so this is where
things come together.
We get a DT descriptions for a couple of new SoCs, all of them
variants of other chips we already support, and usually coming with a
new evaluation board:
- Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
- Qualcomm MDM9615 LTE baseband
- NXP imx6ull, the latest and smallest i.MX6 application processor variant
- Renesas RZ/G (r8a7743 and r8a7745) application processors
- Rockchip PX3, a variant of the rk3188 chip used in Android tablets
- Rockchip rk1108 single-core application processor
- ST stm32f746 Cortex-M7 based microcontroller
- TI DRA71x automotive processors
These are commercially available consumer platforms we now support:
- Motorola Droid 4 (xt894) mobile phone
- Rikomagic MK808 Android TV stick based on Rockchips rx3066
- Cloud Engines PogoPlug v3 based on OX820
- Various Broadcom based wireless devices:
- Netgear R8500 router
- Tenda AC9 router
- TP-LINK Archer C9 V1
- Luxul XAP-1510 Access point
- Turris Omnia open hardware router based on Armada 385
And a couple of new boards targeted at developers, makers or
industrial integration:
- Macnica Sodia development platform for Altera socfpga (Cyclone V)
- MicroZed board based on Xilinx Zynq FPGA platforms
- TOPEET itop/elite based on exynos4412
- WP8548 MangOH Open Hardware platform for IOT, based on Qualcomm MDM9615
- NextThing CHIP Pro gadget
- NanoPi M1 development board
- AM571x-IDK industrial board based on TI AM5718
- i.MX6SX UDOO Neo
- Boundary Devices Nitrogen6_SOM2 (i.MX6)
- Engicam i.CoreM6
- Grinn i.MX6UL liteSOM/liteBoard
- Toradex Colibri iMX6 module
Other changes:
- added peripherals on renesas, davinci, stm32f429, uniphier, sti,
mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
mvebu, allwinner, broadcom, exynos, zynq
- Continued fixes for W=1 dtc warnings
- The old STiH415/416 SoC support gets removed, these never made it
into 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.
- Intel PXA25x can now be booted using devicetree"
