2020-07-13Replace HTTP links with HTTPS ones: drivers/iioAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean
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.

2018-07-15iio: adxl345: Add support for the ADXL375Lars-Peter Clausen
The ADXL375 is fully register map compatible to the ADXL345 (including the device ID register returning the same value ...). The only difference is the resolution of the acceleration sensor. The ADXL375 can measure up to +-200g of acceleration.

2018-06-30iio: accel: adxl345: convert address field usage in iio_chan_specAkinobu Mita
Currently the address field in iio_chan_spec is filled with an accel data register address for the corresponding axis. In preparation for adding calibration offset support, this sets the address field to the index of accel data registers instead of the actual register address. This change makes it easier to access both accel registers and calibration offset registers with fewer lines of code as these are located in X-axis, Y-axis, Z-axis order.
