pps: kc: fix non-tickless system config dependency

2016-10-11T22:06:32Z

CONFIG_NO_HZ currently only sets the default value of dynticks config so if PPS kernel consumer needs periodic timer ticks it should depend on !CONFIG_NO_HZ_COMMON instead of !CONFIG_NO_HZ. Otherwise it is possible to enable it even on tickless system which has CONFIG_NO_HZ not set and CONFIG_NO_HZ_IDLE (or CONFIG_NO_HZ_FULL) set.

pps: do not crash when failed to register

2016-07-23T01:25:54Z

With this command sequence: modprobe plip modprobe pps_parport rmmod pps_parport the partport_pps modules causes this crash: BUG: unable to handle kernel NULL pointer dereference at (null) IP: parport_detach+0x1d/0x60 [pps_parport] Oops: 0000 [#1] SMP ... Call Trace: parport_unregister_driver+0x65/0xc0 [parport] SyS_delete_module+0x187/0x210 The sequence that builds up to this is: 1) plip is loaded and takes the parport device for exclusive use: plip0: Parallel port at 0x378, using IRQ 7. 2) pps_parport then fails to grab the device: pps_parport: parallel port PPS client parport0: cannot grant exclusive access for device pps_parport pps_parport: couldn't register with parport0 3) rmmod of pps_parport is then killed because it tries to access pardev->name, but pardev (taken from port->cad) is NULL. So add a check for NULL in the test there too.

ntp/pps: use y2038 safe types in pps_event_time

2015-10-01T16:59:16Z

The pps_event_time uses two 'timespec' structures internally, which suffer from the y2038 problem. The uses of this structure are fairly self-contained in the pps code, so this replaces them all at once. Unfortunately, this includes the sfc ethernet driver aside from the pps subsystem, so we change that one as well. Both touch the same data structure, and there probably is no good way to split the patch into smaller units. Acked-by: Richard Cochran Acked-by: David S.

ntp/pps: use timespec64 for hardpps()

2015-10-01T16:57:59Z

There is only one user of the hardpps function in the kernel, so it makes sense to atomically change it over to using 64-bit timestamps for y2038 safety. In the hardpps implementation, we also need to change the pps_normtime structure, which is similar to struct timespec and also requires a 64-bit seconds portion. This introduces two temporary variables in pps_kc_event() to do the conversion, they will be removed again in the next step, which seemed preferable to having a larger patch changing it all at the same time.

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

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

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52Z

After the last architecture switched to generic hard irqs the config options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code for !CONFIG_GENERIC_HARDIRQS can be removed. Signed-off-by: Martin Schwidefsky

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: convert class code to use dev_groups

2013-08-20T04:22:34Z

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the pps class code to use the correct field. Cc: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

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.
