[PATCH v2 0/3] cmd/button: return button status

[Heinrich Schuchardt]

To make the button command useful in a shell script it should return the
status of the button.

Adjust the sandbox GPIO driver to keep the output value as input when
switching to input.

Adjust the device-tree labels of the sandbox GPIOs used for buttons.

Enhance the Python unit test to check the button status returned by the
button command.

v2:
	adjust Python test
	adjust GPIO driver

Heinrich Schuchardt (3):
  test: sharpen button label unit test
  drivers: gpio: keep output value for input on sandbox
  cmd/button: return button status
