Hi Michal, >>> I have found your name in connection to net/bluetooth/leds.c trigger. >>> I understand that this trigger will show status of hci controller >>> and this is just working fine. I have tested it without any issue. >>> I am curious if we could use this trigger to handle also gpio signal >>> which is enabling BT. I am using ti chip where we have bt_en connected >>> to gpio. >>> I have seen that people are handling this from userspace by exporting >>> gpio and writing values there but it looks pretty bad to me. >>> >>> Have you ever tried to use bt led trigger also for handling gpio enable >>> signals? Or is there any other nice way how to handle it? >> >> that is the wrong approach. See how hci_intel.c, hci_bcm.c, hci_nokia.c and others are dealing with the GPIO pins in the background. There is no need for any user space hacks anymore. > > I use TI wl1831 over uart with flow control which is using hci_ll.c. > I understand handling when you have specific driver that you need to > handle it. But if this is just over uart where from simply running > "hciattach -n /dev/ttyS1 texas" > I can detect this chip. that one just got integrated with the serdev serial device bus and can be configured via DT.
