Closes: adafruit#7017 * Remove the 'GP23' alias for CYW1 * Remove the 'CYW0' alias for CYW0 * Switch VBUS_SENSE to CYW2, remove 'GP24' alias Code that wants to use SMPS_MODE, VBUS_SENSE and LED while being portable to the W and non-W variants should use those names, not alias names. * Remove A3 / VOLTAGE_MONITOR Right now this cannot be used. The ability to check the voltage monitor should be added back in some fashion in the future.

@anecdata is this an improvement over the status quo? any suggestions on improvements? |

Yes, looks like this prohibits user access to special pins 23, 24, and 25, and adds / fixes user access to |

There was a problem hiding this comment.
The CYW* pins look fine:
>>> led = digitalio.DigitalInOut(board.LED)
>>> led.switch_to_output(False)
>>> led.value = True
>>>
>>> smps_mode = digitalio.DigitalInOut(board.SMPS_MODE)
>>> smps_mode.switch_to_output(False)
>>> smps_mode = True
>>>
>>> vbus_sense = digitalio.DigitalInOut(board.VBUS_SENSE)
>>> vbus_sense.value
True(didn't explore power ramifications of SMPS_MODE)
Should this be inaccessible for now? Maybe it doesn't matter since users can't do anything with it.
>>> gpio29 = analogio.AnalogIn(microcontroller.pin.GPIO29)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: GPIO29 in use
I will approve and merge if this is not a remaining issue. |

This is expected for now |

Code that wants to use SMPS_MODE, VBUS_SENSE and LED while being portable to the W and non-W variants should use those names, not alias names.
Right now the voltage monitor cannot be used. The ability to check the voltage monitor should be added back in some fashion in the future. (#7020)
