staging: iio: ad5933: switch buffer mode to software

2018-01-28T08:24:20+00:00

Since commit 152a6a884ae1 ("staging:iio:accel:sca3000 move
to hybrid hard / soft buffer design.")
the buffer mechanism has changed and the
INDIO_BUFFER_HARDWARE flag has been unused.

Since commit 2d6ca60f3284 ("iio: Add a DMAengine framework
based buffer")
the INDIO_BUFFER_HARDWARE flag has been re-purposed for
DMA buffers.

This driver has lagged behind these changes, and
in order for buffers to work, the INDIO_BUFFER_SOFTWARE
needs to be used.

staging: iio: adc: ad7192: fix external frequency setting

2018-01-28T08:16:24+00:00

The external clock frequency was set only when selecting
the internal clock, which is fixed at 4.9152 Mhz.

This is incorrect, since it should be set when any of
the external clock or crystal settings is selected.

Added range validation for the external (crystal/clock)
frequency setting.
Valid values are between 2.4576 and 5.12 Mhz.

This is a clean-up patch which replaces DEVICE_ATTR() macro with the
file permission specific DEVICE_ATTR_RW() macro for compaction and
readability. Done using coccinelle.

iio: trigger: Fix platform_get_irq's error checking

2017-12-02T12:21:10+00:00

The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.

staging: iio: ad7746: Improve unlocking of a mutex in ad7746_start_calib()

2017-12-02T10:40:07+00:00

* Add a jump target so that a call of the function "mutex_unlock" is stored
  only twice in this function implementation.

* Replace two calls by goto statements.

This issue was detected by using the Coccinelle software.

Merge tag 'staging-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2017-11-14T04:53:28+00:00

Pull staging and IIO updates from Greg KH:
 "Here is the "big" staging and IIO driver update for 4.15-rc1.

  Lots and lots of little changes, almost all minor code cleanups as the
  Outreachy application process happened during this development cycle.
  Also happened was a lot of IIO driver activity, and the typec USB code
  moving out of staging to drivers/usb (same commits are in the USB tree
  on a persistent branch to not cause merge issues.)

  Overall, it's a wash, I think we added a few hundred more lines than
  removed, but really only a few thousand were modified at all.

  All of these have been in linux-next for a while. There might be a
  merge issue with Al's vfs tree in the pi433 driver (take his changes,
  they are always better), and the media tree with some of the odd
  atomisp cleanups (take the media tree's version)"
