gpio: remove gpiobus_attach_bus

2025-08-13T11:14:00+00:00

Since gpiobus_attach_bus can attach the gpiobus child along with its
children in the same bus pass, the parent controller's reference to
gpiobus might not be set by the time the children need it. Instead,
drivers should use gpiobus_add_bus and explicitly call
bus_attach_children.

ftgpio: Fix panic at attach and use better device description

2023-03-02T15:17:04+00:00

Use ftgpio_group_get_status instead of inlining an imperfect
version of it to get correct register and avoid
panic: ftgpio_group_get_ioreg: invalid register 0 for group 0
