I’m migrating from WP8548 modules to WP7702 modules on our customer circuit board. One of our kernel drivers requires CF3_GPIO21 to be used in order to set up the I2C hub.
I understand from these this post that actual GPIO numbers for used but the kernel are different than the actual GPIO numbers. I have followed these posts and tried to build from the Yocto source but I am not having much luck finding the ext_gpio_wp gpiolib-sysfs.c.
Can someone please post the pin mapping or the WP7702 or help me locate it?
