* [dwgpio] Use fdt_reg() to get GPIO port numbersMichael Brown2025-08-072-15/+9Star
| | | | | | | | | | | | | DesignWare GPIO port numbers are represented as unsized single-entry regions. Use fdt_reg() to obtain the GPIO port number, rather than requiring access to a region cell size specification stored in the port group structure. This allows the field name "regs" in the port group structure to be repurposed to hold the I/O register base address, which then matches the common usage in other drivers.
