Hello list, I'am working on an ldisc driver for a hardware board which is connected to a imx6ul cpu board via serial line (/dev/ttymxc7). The underlying serial driver is imx.c. My ldisc code is derived from n_gsm.c and n_hdlc.c and the ldisc driver is attached with ldattach on bootup with this command: /usr/sbin/ldattach -d 29 /dev/ttymxc7 The hardware board needs for the startup a reset signal on this gpio: /sys/class/gpio/gpio77/value Where is the right place in the driver code to toggle that reset signal? and how should I do that exactly? The best would be if the hardware module is turned on first open() of ttymxc7 but I think the ldisc open() is wrong place here. Some advices for a novice to do this the right way?
