#1586179 — [PATCH v2 0/4] ARM: dts: da850-evm: vpif DT changes

This series adds necessary changes to make vpif work on the da850-evm
board.

The first patch only contains whitespace error fixes.

The second patch add a pinctrl node for vpif display pins.

The third adds the UI expander node that is needed to select the video
capture functionality.

The last patch extends the vpif node with an output port.

v1 -> v2:
- used enable-gpios property instead of gpio hogs
- renamed the UI expander
- corrected the commit message in patch 2/4

Bartosz Golaszewski (4):
  ARM: dts: da850-evm: fix whitespace errors
  ARM: dts: da850: add vpif video display pins
  ARM: dts: da850-evm: add the UI expander node
  ARM: dts: da850-evm: add the output port to the vpif node

#1586181 — [PATCH v2 4/4] ARM: dts: da850-evm: add the output port to the vpif node

Extend the vpif node with an output port with a single channel.

NOTE: this is still mostly just hardware description - the actual
driver is registered using pdata-quirks. We need the node however
for correct pin control function selection.
