On some Q8 and other tablets ldo_io1 is used as vcc-touchscreen, config at as such in sun8i-reference-design-tablet.dtsi. Note that it will only be enabled when it us actually referenced by a foo-supply property in the touchscreen node, so for tablets which do not use ldo_io1 as vcc-touchscreen, it will be disabled.
