2018-06-17arm64: dts: rockchip: use SPDX-License-IdentifierKlaus Goger
Update all 64bit rockchip devicetree files to use SPDX-License-Identifiers. All devicetrees claim to be either GPL or X11 while the actual license text is MIT. Therefore we use MIT for the SPDX tag as X11 is clearly wrong.

2017-07-22arm64: dts: rockchip: add ARM Mali GPU node for RK3399 SoCsCaesar Wang
Add Mali GPU device tree node for the RK3399 SoCs, with devfreq opp table. RK3399 and RK3399-OP1 SoCs have a different recommendation table with gpu opp. Also, the ARM's mali driver found on https://developer.arm.com/products/software/mali-drivers/midgard-kernel.

2017-05-30arm64: dts: rockchip: update common rk3399 operating pointsHeiko Stuebner
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. Signed-off-by: Heiko Stuebner <heiko@sntech.de>
2017-03-22arm64: dts: rockchip: describe Gru/Kevin OPPs + CPU regulatorsBrian Norris
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.
