Hello everyone. I have a Linux Serdev driver [1] that uses a specific UART. To actually access the UART directly (`/dev/ttyS4`), I have to enable a device tree [2] and reboot the device. I was wondering if there was a better way to go about it. Is it possible to disable bcfserial (thereby enabling `/dev/ttyS4`) when the driver is removed (using rmmod)? I need access to `/dev/ttyS4` to flash new firmware to BeaglePlay CC1352 using bsl [3]. Having to restart everytime I or anyone else wants to update firmware is not great, while developing. I am looking for a cycle like this: `rmmod driver` -> `flash firmware` -> `modprobe driver`.
