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

|

* In general an attempt is made to include all rails called out by
|
||||
* the schematic as long as those rails interact in some way with
|
||||
* the AP. AKA:
|
||||
* - Rails that only connect to the EC (or devices that the EC talks to)
|
||||
* are not included.
|
||||
* - Rails _are_ included if the rails go to the AP even if the AP
|
||||
* doesn't currently care about them / they are always on. The idea
|
||||
* here is that it makes it easier to map to the schematic or extend
|
||||
* later.
|
||||
*
|
||||
* If two rails are substantially the same from the AP's point of
|
||||
* view, though, we won't create a full fixed regulator. We'll just
|
||||
* put the child rail as an alias of the parent rail. Sometimes rails
|
||||
* look the same to the AP because one of these is true:
|
||||
* - The EC controls the enable and the EC always enables a rail as
|
||||
* long as the AP is running.
|
||||
* - The rails are actually connected to each other by a jumper and
|
||||
* the distinction is just there to add clarity/flexibility to the
|
||||
* schematic.
