Instead of allocating a struct pps_gpio_platform_data in the DT case, store the necessary information in struct pps_gpio_device_data itself. This avoids an additional allocation and the ifdef. It also gets rid of some indirection. Also use dev_err instead of pr_err in the changed code.

Device-Tree Bindings for a PPS Signal on GPIO
|
|
|
|
These properties describe a PPS (pulse-per-second) signal connected to
|
|
a GPIO pin.
|
|
|
|
Required properties:
|
|
- compatible: should be "pps-gpio"
|
|
- gpios: one PPS GPIO in the format described by ../gpio/gpio.txt
|
|
|
|
Optional properties:
|
|
- assert-falling-edge: when present, assert is indicated by a falling edge
|
|
(instead of by a rising edge)
|
|
|
|
Example:
|
|
pps {
|
|
compatible = "pps-gpio";
|
|
gpios = <&gpio2 6 0>;
|
|
|
|
assert-falling-edge;
|
|
};
