Subject: Controlling the same I2C device from user and kernel space
Date: Tue, 26 Mar 2024 10:52:05 +0100 [thread overview]
Message-ID: <CA+DkFDbdbSOrPv+WF2ofRS5_pfKCsPWvJe5BbXadGOKBBy8HkQ@mail.gmail.com> (raw)
Hi, I've got a question. I have an I2C device (FPGA) connected to my
board. This device implements a hardware watchdog and GPIO expander.
My question is - can I control this device from userspace (watchdog
part) using spidev driver and still be able to develop a kernel driver
that controls GPIO expander part without any additional locking
mechanisms?
Best regards
Patryk
