1edcd36fcb ARM: sunxi: Convert pinctrl nodes to generic bindings
Now that we can handle the generic pinctrl bindings, convert our DT to it.

d312f6fb80 ARM: sunxi: Remove useless allwinner,drive property
The allwinner,drive property set to 10mA was really considered as our
default. Remove all those properties entirely to make that obvious.

b223d6242c ARM: dts: sun6i: yones-toptech-bs1078-v2: Drop constraints on dc1sw regulator
This is the same issue fixed in commit dcf5341f01 ("ARM: dts:
sun8i-q8-common: Do not set constraints on dc1sw regulator").
Commit message copied:

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.

5058ec4a95 dts: sun6i: yones toptech bs1078 v2: Add AXP221 support to dts
Enable the axp221 PMIC chip in the dts file.

Allows board to power off correctly from the poweroff command

This board requires dc1sw to be enabled in order to provide a power source
for the 5V DCDC converter that powers USB2.

This board uses dldo1 for 3.3V wifi power

This board requires dldo3 to be enabled at 2.8V in order to provide voltage
to the pullup resistors for the i2c0 bus.
