- Hoag and Aula do not have a USB based 5V bus source, so do not touch CC4 pin. - More importantly, in T210B01 the GPIO AO IO rail seems to be working properly from boot. Plus it also seems that is needed by various components. That was found when running on Aula. It was causing an immediate hang. Probably SoC wide. Only allow control of it on T210 to avoid such issues.
