This patch series adds support for the Pine64 touch panel to the
rockpro64 single board computer.
This panel attaches to the dsi port and includes an i2c touch screen.

The first two patches involve making the reset pin to the Feiyang
fy07024di26a30d panel optional. On the rockpro64 and quartz64-a this pin
is tied to dvdd and automatically comes high when power is applied.
The third patch adds the device tree nodes to rockpro64 to permit the
panel to be used.
The fourth patch is an example patch to enable this support, tagged do
not merge as this is something for the end user to enable only when they
have the panel attached.
