1.Modify the device tree as follows: pps { compatible = "pps-gpio"; gpios = <&tegra_main_gpio TEGRA234_MAIN_GPIO(N, 2) GPIO_ACTIVE_LOW>; //assert-rising-edge; //assert-falling-edge; status = "okay"; }; 2.Separa
Hi, We are trying to use IRQ04/GPIO3_28 pin for PPS. This pin is connected to FPGA which generates PPS.We have enabled PPS driver in the kernel device tree pps { compatible = "pps-gpio"; gpios = <&gpio2 28 GPIO_ACTIVE_HIGH>; assert-falling-edge;...
Please note that in order to use the module with any other board using the device tree infrastructure, the following matching definitions are required in the device tree: pps-gen node defined for the PPS GPIO pps-gen-gpio value of ".compatible" property in pps-gen node pps-gen-gpio propert...

We have tested the driver with kernel 5.4.152 on a Beaglebone Black where P9 pin 16 (GPIO1_19) is used as PPS output. The corresponding modified device tree file is here shown. Usage If you use a Beaglebone Black and want to change the PPS output pin, you have to modify your device...

We have enabled PPS driver in the kernel device tree pps { compatible = "pps-gpio"; gpios = <&gpio2 28 GPIO_ACTIVE_HIGH>; assert-falling-edge;};and CONFIG_PPS_CLIENT_GPIO in the kernel config. We are unable to capture interrupts....
