iio: ABI: add note about configuring other attributes during buffer capture

2022-02-21T19:33:05Z

It might be impossible to configure other attributes (e.g.: events, scale, sampling rate) if they impact the currently active buffer capture session. On ADXL367, writing to register before 0x2E requires the device to be placed in standby mode, otherwise the changes might be effective for only part of a measurement. To ensure this requirement, the configuration attributes of the IIO device try to claim direct mode before switching to standby mode. During a buffer capture, direct mode cannot be claimed, and the attribute write callback returns -EBUSY. Describe this behavior in the buffer/enable attribute description.

iio: ABI: document mag_referenced

2022-02-21T19:33:05Z

Some accelerometers that support activity and inactivity events also support a referenced mode, in which the gravitational acceleration is taken as a point of reference before comparing the acceleration to the specified activity and inactivity magnitude. For example, in the case of the ADXL367, for activity detection, the formula is: abs(acceleration - reference) > magnitude Add a new event type that makes this behavior clear.

Merge tag 'staging-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

2021-07-05T21:01:53Z

Pull staging / IIO driver updates from Greg KH: "Here is the big set of IIO and staging driver patches for 5.14-rc1. Loads of IIO driver updates and additions in here, the shortlog has the full details. For the staging side, we moved a few drivers out of staging, and deleted the kpc2000 drivers as the original developer asked us to because no one was working on them anymore. Also in here are loads of coding style cleanups due to different intern projects focusing on the staging tree to try to get experience doing kernel development. All of these have been in the linux-next tree for a while with no reported problems" * tag 'staging-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (744 commits) staging: hi6421-spmi-pmic: cleanup some macros staging: hi6421-spmi-pmic: change identation of a table staging: hi6421-spmi-pmic: change a return code staging: hi6421-spmi-pmic: better name IRQs staging: hi6421-spmi-pmic: use devm_request_threaded_irq() staging: hisilicon,hi6421-spmi-pmic.yaml: cleanup descriptions spmi: hisi-spmi-controller: move driver from staging phy: phy-hi3670-usb3: move driver from staging into phy staging: rtl8188eu: remove include/rtw_debug.h header staging: rtl8188eu: remove GlobalDebugLevel variable staging: rtl8188eu: remove DRIVER_PREFIX preprocessor definition staging: rtl8188eu: remove RT_TRACE macro staging: rtl8188eu: remove all RT_TRACE calls from hal/rtl8188eu_recv.c staging: rtl8188eu: remove all RT_TRACE calls from hal/hal_intf.c staging: rtl8188eu: remove all RT_TRACE calls from hal/rtl8188eu_xmit.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_xmit.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_pwrctrl.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_recv.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_ioctl_set.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_ieee80211.c ...

iio: ABI: sysfs-bus-iio: avoid a warning when doc is built

2021-05-27T16:08:05Z

The description of those vars produce this warning: Documentation/ABI/testing/sysfs-bus-iio:799: WARNING: Inline emphasis start-string without end-string. Due to an asterisk, which is the markup for emphasis. One possible fix would be to use ``*_timeout`` to avoid it, but looking at the descriptions of other fields in this file, a common pattern is to refer to "these" when talking about the API calls that are described. So, change the text in order to preserve the meaning while avoiding the need of using an asterisk there.

iio: Documentation: move incompatible ABI to obsolete

2021-05-17T12:49:11Z

Commit 63cd35f34d2e ("iio: Documentation: update definitions for bufferY and scan_elements") updated iio documentation in order to point to the newly per-buffer API, as it is now possible to support multi buffers. While the previous ABI will be kept forever, the best is for applications to use the 5.11+ ABI. So, move the legacy one ABI/obsolete. This fixes an issue with scripts/get_abi.pl, that doesn't accept two different Kernel version support for the same API set.

iio:ABI docs: Move specific description of out_altvoltageX_frequency to main docs.

2021-05-17T12:49:10Z

The adf4371 has channels that are very closely coupled, so additional documentation is needed to express these constraints. Unfortunately having the same sysfs filename in multiple documentation does not work well when generating automated documentation. To avoid this issue, we add a new device specific description to the main docs and remove the one in the device specific file. Fixes $ scripts/get_abi.pl validate Warning: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency is defined 2 times: ./Documentation/ABI/testing/sysfs-bus-iio-frequency-adf4371:0 ./Documentation/ABI/testing/sysfs-bus-iio:599 Cc: Alexandru Ardelean Reported-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Cameron Link: https://lore.kernel.org/r/20210117153816.696693-8-jic23@kernel.org
