I tend to disagree here. I consider the bank defines RK_GPIOx to be deprecated and highly discourage them being used in new boards. They only encode the same number again (2 -> RK_GPIO2 etc) and therefore don't bring any useful addition over using the bank number directly. Slightly similar argument for the per-pin defines. While the external pins are described in the A/B/C/Dx notation for pinmux purposes, the gpio controllers on top use a regular 0-31 numbering. Also you cannot name constants generic GPIO_x, simply because that may conflict with other overly generic constant names. So I'm not yet convinced that these improve readability, but they would definitly need a RK_* prefix to make them specific.
