Some devices have multiple pinctrl regions; for instance, main pinctrl and mcu pinctrl. Currently there can only be a single pinctrl instance picked form a DT label. This patch makes the pinctrl driver initialise one instance for each node with correct compatible string. Signed-off-by: Amneesh Singh <a-singh7@ti.com>
