The pin configuration (done with generic pin controller helpers and as expressed by bindings) requires children nodes with either: 1. "pins" property and the actual configuration, 2. another set of nodes with above point. The qup_spi2_default pin configuration uses alreaady the second method with a "pinmux" child, so configure drive-strength similarly in "pinconf". Otherwise the PIN drive strength would not be applied.
