Instead of relying on indexes pointing to edma private date in the global pointer array, pass the private data pointer via the public API.
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. ...
