147f6ec570 arm64: dts: rockchip: Assign mic irq to correct device for Gru
Currently we are assigning mic irq to rt5514 i2c driver, which is wrong.
Assign it to rt5514 spi driver instead.

a4c6bbcb9e arm64: dts: rockchip: Fix wrong rt5514 dmic delay property for Gru
According to rt5514 dt-binding, it should be "realtek,dmic-init-delay-ms".

813b04f758 arm64: dts: rockchip: enable the GPU for RK3399-GRU
This patch enables the gpu and adds the mali-supply power for RK3399-GRU
devices.

6f07176fc3 arm64: dts: rockchip: Use vctrl regulators for dynamic CPU voltages on Gru/Kevin
The Gru device tree currently contains entries for the regulators
ppvar_bigcpu, ppvar_litcpu, ppvar_gpu and ppvar_centerlogic; however,
the regulators have not been enabled, due to the lack of binding and driver
support for keeping the over-voltage protection (OVP) at bay and
preventing unintended regulator shutdowns on voltage downshifts.

Now, the vctrl regulator driver has been merged, along with new bindings
for asymmetric settling time. The driver is OVP aware, it splits larger
voltage decreases in multiple steps when necessary and adds required
delays.

This change renames each of the aforementioned regulators to
<orig_name>_pwm and adds a new vctrl regulator named <orig_name>.
The vctrl regulators use the voltage of their corresponding PWM regulator
as control voltage. The OVP related values are empirical and stem from
the Chrome OS kernel tree.

2fb634de8d arm64: dts: rockchip: Update CPU regulator voltage ranges for Gru
Gru derivatives besides Kevin have slightly different voltage ranges for
their CPU regulators. Let's keep the base Gru file accurate and let
Kevin override.

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.

acaa71a6c7 arm64: dts: rockchip: describe Gru/Kevin OPPs + CPU regulators
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
boards.

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.

48f4d9796d arm64: dts: rockchip: add Gru/Kevin DTS
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

Not tested:
 * Audio
