 driver

Hi,

When I check "rockchip,gpio-bank" with YAML it turns out that
rk3288-veyron-XXX has 'gpio-line-names' as 'extra' property.
It is not defined in the "rockchip,pinctrl.txt" document, but in
~/.local/lib/python3.5/site-packages/dtschema/schemas/gpio/gpio.yaml

Where is that in use?
In this driver or external?
Can it be removed from mainline dts?

Johan

/arch/arm/boot/dts/rk3288-veyron-fievel.dt.yaml: gpio7@...e0000:
'gpio-line-names' does not match any of the regexes: 'pinctrl-[0-9]+'
	From schema:
/Documentation/devicetree/bindings/gpio/rockchip,gpio-bank.yaml
