[Ondrej Jirman <megous@megous.com>]

This series adds an initial support for Pine64 PinePhone.

Please take a look.

thank you and regards,

Changes in v2:
- make i2c2_pins default pinctrl config for i2c2 node
- add description of the differences between 1.0 and 1.1 to the
  commit message
- added copyright header for Martijn Braam
- drop pinctrl config from i2c1 and i2c2 nodes, since it's
  now the default
- extend comments on i2c2 and uart3 nodes to be more clear
- rebased on top of linux-next and resolved conflicts
- dropped the function-enumerator from leds

Changes not made:
- I didn't drop pinctrl configs on mmc0, mmc2 and uart3
  - these are actually not default in dtsi, as was suggested
- gpio-leds kept with the new function/color binding, but I dropped
  the function-enumerator

It seems intention for the future (since about 06-2019[0]) is for LEDs to not
have a devicename in their class name, because that's determinable
from the sysfs in other ways, and to use the function and color
properties instead of label in DT.

function-enumerator is supposed to be used if function/color don't
make the LED name unique for the board. [1] So I dropped function-enumerator
from my series, as it just added a numeric suffix to the LED name
for no reason.
