ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator
dc1sw is an on/off only regulator and as such it cannot have constraints. This is a limitation of the kernel regulator implementation which resolves supplies on the first regulator_get(), which is done after applying constraints, and applying the constrains will fail because it calls _regulator_get_voltage() and _regulator_do_set_voltage() both of which will fail on a switch regulator when there is no supply (yet). This causes registering of all axp22x regulators to fail with the following errors: [ 1.395249] vcc-lcd: failed to get the current voltage(-22) [ 1.405131] axp20x-regulator axp20x-regulator: Failed to register dc1sw [ 1.412436] axp20x-regulator: probe of axp20x-regulator failed with error -22 This commit removes the constrains on dc1sw / vcc-lcd fixing this problem note that dcdc1 itself is contrained to the exact same values, so this does not change anything.
