iio:imu:adis: Move exports into IIO_ADISLIB namespace

2022-02-18T11:42:26Z

In order to avoid unneessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the various specific device drivers that use them.

iio: adis: Cleanout unused headers

2021-06-04T08:28:10Z

0-day recently added the include-what-you-use header checker and it gave a warning on an adis patch. As such I decided to run it on all the adis drivers and see if it made sensible suggestions. Note this doesn't represent a complete list of what it suggested changing as I filtered out a few on the basis they are standard headers used to effectively include a bunch of other headers. Could split this into a patch per driver if people prefer. Note to anyone else trying this tool is that it is somewhat of a loose cannon so you will be wanting to carefully check any suggestions before proposing patches! I thought about also reorganising the headers whilst here, but that would make this patch harder to read, or lead to another rather noisy patch across most of the files.

staging: iio: adis16240: add blank line before struct definition

2020-10-26T05:53:09Z

Add a blank line before starting structure definition as per coding style guidelines. Issue reported by checkpatch script. Acked-by: Julia Lawall Signed-off-by: Deepak R Varma Link: https://lore.kernel.org/r/20201011104800.GA29412@ubuntu204 Signed-off-by: Greg Kroah-Hartman

staging: iio: adis16240: Use Managed device functions

2020-09-16T18:06:10Z

Use the adis managed device functions to setup the buffer and the trigger. The ultimate goal will be to completely drop the non devm version from the lib. Since we are here, drop the `.remove` callback by further using devm functions.

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59Z

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: imu: adis: Add self_test_reg variable

2020-03-08T17:28:30Z

This patch adds a dedicated self_test_reg variable. This is also a step to let new drivers make use of `adis_initial_startup()`. Some devices use MSG_CTRL reg to request a self_test command while others use the GLOB_CMD register. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: adis: Remove startup_delay

2020-01-12T11:34:13Z

All timeouts are now handled by a dedicated timeout struct. This variable is no longer needed. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: adis: Introduce timeouts structure

2020-01-12T11:34:12Z

The adis library only allows to define a `startup_delay` which for some devices is enough. However, other devices define different timeouts with significantly different timings which could lead to devices to not wait enough time or to wait a lot more than necessary (which is not efficient). This patch introduces a new timeout struct that must be passed into `adis_init()`. There are mainly, for now, three timeouts used. This is also an introductory patch with the goal of refactoring `adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are replicating code for the device initial setup. With some changes (being this the first one) we can pass this to `adis_initial_startup()`. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

staging: iio: accel: adis16240: enforce SPI mode on probe function

2019-12-15T12:18:49Z

According to the datasheet, this driver supports only SPI mode 3, so we should enforce it on probe function. Signed-off-by: Rodrigo Carvalho Signed-off-by: Jonathan Cameron
