iio: frequency: adf4350: Remove redundant null check before clk_disable_unprepare

Because clk_disable_unprepare() already checked NULL clock parameter, so the additional check is unnecessary, just remove it. Signed-off-by: Xu Wang Link: https://lore.kernel.org/r/20201218094647.1386-1-vulab@iscas.ac.cn Signed-off-by: Jonathan Cameron

iio: frequency: adf4350: Replace indio_dev->mlock with own device lock

2020-09-16T17:58:01+00:00

As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock. The lock protect the state of the device from potential concurrent writes. The device is configured via a sequence of SPI writes, and this lock is meant to prevent the start of another sequence before another one has finished. This is part of a bigger cleanup.

iio: frequency: ad9523: convert rest of driver to device managed functions

2020-08-22T09:53:14+00:00

The driver pretty much uses device managed functions. The only left-over is the iio_device_register() function, which also requires an action-or-reset hook to disable the regulator on the remove and error path. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59+00:00

This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: adf4350: Convert to use GPIO descriptor

2019-12-15T11:42:16+00:00

The lock detect GPIO line is better to grab using a GPIO descriptor. We drop the pdata for this: clients using board files can use machine descriptor tables to pass this GPIO from static data.
