Pull "Rockchip dts64 updates for 4.15 part1" from Heiko Stübner:

The biggest step forward is probably the enablement of display support
on the rk3399-firefly, which got its default serial set as well and
got cec support as well.
Gru boards got their touchpad support refined to actually mark the button
correctly and also git their rt5514 dsp added.
And finally the rk3328 eval board got its cpu regulator and mmc nodes.
