iio: adis: Remove startup_delay

2020-01-12T11:34:13+00:00

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

2020-01-12T11:34:12+00:00

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

2019-12-15T12:18:49+00:00

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

staging: iio: ad9834: add a check for devm_clk_get

2019-10-18T19:08:01+00:00

ad9834_probe misses a check for devm_clk_get and may cause problems. Add a check like what ad9832 does to fix it. Signed-off-by: Chuhong Yuan Reviewed-by: Dan Carpenter Reviewed-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

staging: iio: ADIS16240: Remove unused include

2019-09-15T09:51:23+00:00

'#include' isn't being used anywhere. Remove it. Signed-off-by: Rohit Sarkar Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: Add system calibration support

2019-09-08T09:35:56+00:00

This patch will add a system calibration attribute for each channel. Using this option the user will have the ability to calibrate each channel for zero scale and full scale. It uses the iio_chan_spec_ext_info and IIO_ENUM to implement the functionality. Signed-off-by: Mircea Caprioru Signed-off-by: Jonathan Cameron

staging: iio: accel: adis16240: Improve readability on write_raw function

2019-08-18T19:12:52+00:00

Replace shift and minus operation by GENMASK macro and remove the local variables used to store intermediate data. Signed-off-by: Rodrigo Ribeiro Carvalho Reviewed-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: Add low_pass_3db_filter_frequency

2019-08-18T18:33:51+00:00

By adding this option we are able to remove the sync3 field and dt binding. When setting the required cutoff frequency we also determine the ADC configuration for chop and sync filter. Signed-off-by: Mircea Caprioru Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: Remove platform data

2019-08-18T18:23:00+00:00

This patch removes the reference voltage entry from the platform_data structure. This is no longer needed since the reference voltage is obtained from the device tree. With this we also remove the entire ad7192.h file. The undefined reference voltage warning is promoted to an error signaling a problem with the device tree.

staging: iio: ad2s1210: Use device-managed API

2019-07-27T21:52:06+00:00

Use device-managed API to simplify the code. The remove function is redundant now and can be deleted. Signed-off-by: Chuhong Yuan Reviewed-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron
