Hi everyone,
Have anyone used the PPS driver on the uClinux? I would like to know what I need in term of the HDL design or a megafunction I can purchase so I can interface with this driver? Thanks in advance if anyone can share your experience using this driver on the uClinux. Thanks.Link Copied

I still have no luck on the PPS client driver on my uClinux running on the NIOS2. Can anyone kindly point me to the right direction, since I am using a device tree and believe this doesn't support device tree, right? What do I need to add/modify so I can use a input GPIO as a source? I saw a google post to add this code to (?? an unknown) and then you need to call pps_init in the configuration routine (?? not sure what it mean)
add /* PPS-GPIO platform data */ static struct pps_gpio_platform_data pps_gpio_info = { .assert_falling_edge = false, .capture_clear= false, .gpio_pin=63, .gpio_label="PPS", }; static struct platform_device pps_gpio_device = { .name = "pps-gpio", .id = -1, .dev = { .platform_data = &pps_gpio_info }, }; static void pps_init(int evm_id, int profile) { int err; err = platform_device_register(&pps_gpio_device); if (err) { pr_warning("Could not register PPS_GPIO device"); } } Thanks in advance for any help
