So, the next question would be what if I just want to enable one or the other (and take that decision at runtime) ? Where do I put the pinctrl/clocks/regulators in the DT ? I guess it can become an issue to enable both WiFi and BT at the same time if both SDIO and UART are trying to handle the same pinctrl and regulators. -- Alexandre Belloni, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
