Commit 587f7a694f01 ("gpio: davinci: Use dev name for label and automatic base selection") broke the GPIO support on DaVinci boards in legacy mode by allowing gpiolib to set the GPIO base automatically.
DaVinci board files use the legacy GPIO API with hard-coded GPIO line numbers. Use the new fields in struct davinci_gpio_platform_data to manually set the GPIO base to 0.
