5fd3ffb92d arm64: dts: rockchip: update common rk3399 operating points
The rk3399 has multiple variants with different frequency ratings.
The operating points currently in the kernel stem from the op1 variant
used in Gru ChromeOS devices and may not be suitable for general rk3399
chips. Therefore bring it back to the official general operating points.

7cd1ed45d4 arm64: dts: rockchip: introduce rk3399-op1 operating points
The OP1 is a rk3399 variant used in ChromeOS devices with a slightly
higher frequency rating compared to the regular rk3399, but right now
the only available operating points don't match either variant
with both needing adjustments to actually fit their specs.

Therefore introduce separate operting points, from the ChromeOS kernel,
for the OP1 and use it on Gru devices.

41b464ef10 arm64: dts: rockchip: fix PCIe domain number for rk3399
It's suggested to fix the domain number for all PCIe
host bridges or not set it at all. However, if we don't
fix it, the domain number will keep increasing ever when
doing unbind/bind test, which makes the bus tree of lspci
introduce pointless domain hierarchy. More investigation shows
the domain number allocater of PCI doesn't consider the conflict
of domain number if we have more than one PCIe port belonging to
different domains. So once unbinding/binding one of them and keep
others would going to overflow the domain number so that finally
it will share the same domain as others, but actually it shouldn't.
We should fix the domain number for PCIe or invent new indexing
ID mechanisms. However it isn't worth inventing new indexing ID
mechanisms personlly, Just look at how other Root Complex drivers
did, for instance, broadcom and qualcomm, it seems fixing the domain
number was more popular. So this patch gonna fix the domain number
of PCIe for rk3399.

531b3c49b3 arm64: dts: rockchip: remove wrongly added idle states on rk3368
As reported by Lorenzo, the residency/latency values defined in the
idle-state for rk3368 "make no sense". When introducing them I
simply took the idle-state node from the vendor kernel in error
as I didn't look up if these values were sane in the first place.

Talking to people and determining why they were used in this way
showed that it was meant to make sure the cpu_suspend callback
got initialized which at the 3.10 time was somehow required even
for wfi-based idle handling.

Of course the generic arch_cpu_idle() now does wfi-based idle-handling
already and the rk3368 does not implement any other idle states than
the default WFI, so these wrong idle-states should go away.

Used for Gru/Kevin only, as they're the only ones which have a described
CPU regulator. Also, I'm not sure we've validated this table non-Gru

At the same time, partially describe PWM regulators for Gru, so cpufreq
doesn't think it can crank up the clock speed without changing the
voltage. However, we don't yet have the DT bindings to fully describe
the Over Voltage Protection (OVP) circuits on these boards. Without that
description, we might end up changing the voltage too much, too fast.

Add the pwm-regulator descriptions and associate the CPU OPPs, but leave
them disabled.

Kevin is part of a family of boards called Gru. As best as possible, the
properties shared by the Gru family are placed in rk3399-gru.dtsi, while
Kevin-specific bits are in rk3399-gru-kevin.dts. This does not add full
support for the base Gru board.

Working and tested (to some extent):
 * EC support -- including keyboard, battery, PWM, and probably more
 * UART / console
 * Thermal
 * Touchscreen
 * Touchpad
 * Digitizer (regulator still WIP)
 * PCIe / Wifi
 * Bluetooth / Webcam
 * SD card
 * eMMC
 * USB2 on TypeC
   - This works much of the time, but USB3 devices may or may not detect
     properly. Waiting on proper extcon support for USB3 over TypeC.
   - Depends on XHCI/DWC3 fixes for ARM64 that still haven't landed
 * Backlight

Not working:
 * CPUFreq -- relies on special OVP support for our PWM regulator
   circuits
 * EC / extcon support -- and with it, USB3/TypeC/DP
 * DRM -- won't even build on ARM64, so all display, eDP, etc. is not
   enabled

b5d1c57299 arm64: dts: rockchip: add u2phy clock for ehci and ohci of rk3399
We found that the suspend process was blocked when it run into
ehci/ohci module due to clk-480m of usb2-phy was disabled.

The root cause is that usb2-phy suspended earlier than ehci/ohci
(usb2-phy will be auto suspended if no devices plug-in). and the
clk-480m provided by it was disabled if no module used. However,
some suspend process related ehci/ohci are base on this clock,
so we should refer it into ehci/ohci driver to prevent this case.

The u2phy clock flow like this:
===
      u2phy ________________
           |                |    |-----> UTMI_CLK ---------> | EHCI |
OSC_24M ---|---> PHY_PLL----|----|
           |________^_______|    |-----> 480M_CLK ---|G|---> | USBPHY_480M_SRC| ----> USBPHY_480M for SoC

482c3e8835 ARM: 64-bit DT updates for v4.10
A couple of interesting new SoC platforms are now supported, these are
 the respective DTS sources:
 
 - Samsung Exynos5433 mobile phone platform, including an (almost) fully
   supported phone reference board.
 - Hisilicon Hip07 server platform and D05 board, the latest iteration
   of their product line, now with 64 Cortex-A72 cores across two
   sockets.
 - Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
   line, used in Android tablets and ultra-cheap development boards
 - NXP LS1046A Communication processor, improving on the earlier LS1043A
   with faster CPU cores
 - Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
   mobile phone SoCs
 - Early support for the Nvidia Tegra Tegra186 SoC
 - Amlogic S905D is a minor variant of their existing Android consumer
   product line
 - Rockchip PX5 automotive platform, a close relative of their popular
   rk3368 Android tablet chips
 
 Aside from the respective evaluation platforms for the above
 chips, there are only a few consumer devices and boards added
 this time:
 
 - Huawei Nexus 6P (Angler) mobile phone
 - LG Nexus 5x (Bullhead) mobile phone
 - Nexbox A1 and A95X Android TV boxes
 - Pine64 development board based on Allwinner A64
 - Globalscale Marvell ESPRESSOBin community board based on Armada 3700
 - Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive  board
 
 For the existing platforms, we get bug fixes and new peripheral support
 for Juno, Renesas, Uniphier, Amlogic, Samsung, Broadcom, Rockchip, Berlin,
 and ZTE.
 
 Conflicts:
 - Documentation/devicetree/bindings/arm/shmobile.txt: a
   rename/add conflict, keep both modifications and maintain
   alphabetical ordering.
 - arch/arm64/boot/dts/*/*.dtsi: nodes were added in netdev,
   mmc and clk, keep both sides in each case.

e6186820a7 arm64: dts: rockchip: Arch counter doesn't tick in system suspend
The "arm,no-tick-in-suspend" property was introduced to note
implementations where the system counter does not quite follow the ARM
specification that it "must be implemented in an always-on power
domain".

Particularly, RK3399's counter stops ticking when we switch from the
24MHz clock to the 32KHz clock in low-power suspend, so let's mark it as
such.

 Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far

 The most important changes for dwc2 are the peripheral side DMA support
 implemented by Synopsys folks and support for the new IOT dwc2
 compatible core from Synopsys.
 
 In dwc3 land we have support for high-bandwidth, high-speed isochronous

 Apart from these, we have our usual set of cleanups, non-critical fixes,

2afc1db0c5 arm64: dts: rockchip: add gmac needed pclk for rk3399 pd
This patch fixes that sometimes hang at start-up time of the system.
As the below log:
...
[   11.136543] calling  pm_genpd_debug_init+0x0/0x60 @ 1
[   11.141602] initcall pm_genpd_debug_init+0x0/0x60 returned 0 after 11 usecs
[   11.148558] calling  genpd_poweroff_unused+0x0/0x84 @ 1
<hang>

In some cases, the rk3399 should turn off the gmac power domain to save
power if some boards didn't register the gmac device node for rk3399.
Then, rk3399 need to make sure the gmac's pclk enabled if we need
operate the gmac power domain. (Due to the NOC had enabled always)
