It maps the required BAR1 region via `dm_pci_map_bar`\nand uses internal registers to control pin state and direction.\n\nThis driver is required for platforms using EG20T, such as P8700-based\nsystems, to access GPIOs through the standard U-Boot DM GPIO framework.\n\nSigned-off-by: Chao-ying Fu <cfu@mips.com>\nSigned-off-by: Uros Stajic <uros.stajic@htecgroup.com>\n---\n
