Fixes V2: * make get_mount_matrix() functions more readable (use temp variable) (suggested by Jonathan and Andy) * add these readability improvements also for ak8975 and mpu6050 (suggested by Jonathan and Andy) * squash bindings documentation into single commit for better discussion (suggested by Linus) * FOR DISCUSSION: add some more clarifications to the bindings documentation and an attempt to define the magnetometer orientation * add "iio: Allow to read mount matrix from ACPI" to the beginning of the series to make it compile (suggested by Andy) * replace of_iio_read_mount_matrix() by iio_read_mount_matrix() (required by "iio: Allow to read mount matrix from ACPI") * drop patch to convert bma180 to devm (potential race) (suggested by Jonathan)
PATCH V1 2019-02-20 15:01:02: This patch series adds the mount-matrix to several iio sensor drivers used in handheld devices.
The mount-matrix translates the quite arbitrary orientation of the sensor on some printed circuit board to user-tangible orientation in handheld devices that relates to typical screen orientation.
There was a bindings documentation by Linus Walleij but the patch did not make it into mainline. Therefore I resend it here.
Next I have added some clarifications (at least I hope it clarifies) in a second patch.
Finally, the patch set implements the hooks for the mount matrix in several iio drivers: bmc150, bma180, bmg160, itg3200, hmc5843. This includes also one patch for the bma180 to convert it to devm API.
We use them in different variants of the omap3-gta04 so a separate patch set will provide device tree additions for them.
