pps: pps-gpio PPS ECHO implementation

2019-05-15T02:52:51Z

This patch implements the PPS ECHO functionality for pps-gpio, that sysfs claims is available already. Configuration is done via device tree bindings. No changes are made to userspace interfaces. This patch was originally written by Lukas Senger as part of a masters thesis project and modified for inclusion into the linux kernel by Tom Burkart.

pps: descriptor-based gpio

2019-05-15T02:52:51Z

This patch changes the GPIO access for the pps-gpio driver from the integer based API to the descriptor based API. The integer based API is considered deprecated and the descriptor based API is the preferred way to access GPIOs as per Documentation/driver-api/gpio/intro.rst No changes are made to userspace interfaces.

pps: using ERR_PTR instead of NULL while pps_register_source fails

2018-11-27T09:05:36Z

pps_register_source() has keeps error codes in a local variable, but it does not make use of the code. This patch let it return the errcode in case of failure. Suggested-by: Richard Cochran Signed-off-by: YueHaibing Acked-by: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

pps: clients: drop owner assignment from platform_drivers

2014-10-20T14:21:28Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

drivers/pps/clients/pps-gpio.c: remove redundant of_match_ptr

2013-11-13T03:09:35Z

The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/pps/clients/pps-gpio.c: remove unnecessary platform_set_drvdata()

2013-09-11T22:59:34Z

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

pps-gpio: add device-tree binding and support

2013-07-03T23:08:06Z

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.
