41a7d671 - iio: ABI: stm32-timer-trigger: Fuse unusual ABI into main doc.

Sun, 26 Jun 2022 16:55:10 +0000

iio: ABI: stm32-timer-trigger: Fuse unusual ABI into main doc.We can't duplicate the description of sampling_frequency. This devicehas some unusual requirements which we solved by giving asampling_frequency of 0 special meaning. As such add a noteabout this unusual usage to the main documentation.Whilst I don't particularly like this resolution, it is the bestI could come up with given earlier discussion on this topic.Link: https://lore.kernel.org/linux-iio/20210315101217.00002c50@Huawei.com/Signed-off-by: Jonathan Cameron Cc: Fabrice Gasnier Reviewed-by: Mauro Carvalho Chehab Link: https://lore.kernel.org/r/20220626165511.602202-4-jic23@kernel.org List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32

docs: ABI: testing: iio: stm32: remove re-introduced unsupported ABIRemove unsupported ABI that has been re-introduced due to a rebase hunk.This ABI has been moved in the past in commit b299d00420e2("IIO: stm32: Remove quadrature related functions from trigger driver")This also fixes a couple of warnings seen with:./scripts/get_abi.pl validate 2>&1|grep iioFixes: 34433332841d ("docs: ABI: testing: make the files compatible with ReST output")Acked-by: Jonathan Cameron Signed-off-by: Fabrice Gasnier Link: https://lore.kernel.org/r/1604685016-2434-1-git-send-email-fabrice.gasnier@st.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32

4adec7da - iio: stm32 trigger: Add quadrature encoder device

Tue, 04 Apr 2017 07:47:51 +0000

iio: stm32 trigger: Add quadrature encoder deviceOne of the features of STM32 trigger hardware block is a quadratureencoder that can counts up/down depending of the levels and edgesof the selected external pins.This patch allow to read/write the counter, get it direction,set/get quadrature modes and get scale factor.When counting up preset value is the limit of the counter.When counting down the counter start from preset value down to 0.This preset value could be set/get by using/sys/bus/iio/devices/iio:deviceX/in_count0_preset attribute.Signed-off-by: Benjamin Gaignard Reviewed-by: William Breathitt Gray Signed-off-by: Jonathan Cameron List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32

93fbe91b - iio: Add STM32 timer trigger driver

Fri, 20 Jan 2017 09:15:07 +0000

iio: Add STM32 timer trigger driverTimers IPs can be used to generate triggers for other IPs likeDAC or ADC.Each trigger may result of timer internals signals like counter enable,reset or edge, this configuration could be done through "master_mode"device attribute.Since triggers could be used by DAC or ADC their names are definedin include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_triggerfunction could be used to check if the trigger is valid or not."trgo" trigger have a "sampling_frequency" attribute which allow to configuretimer sampling frequency.version 8:- change kernel version from 4.10 to 4.11 in ABI documentationversion 7:- remove all iio_device related code- move driver into trigger directoryversion 5:- simplify tables of triggers- only create an IIO device when neededversion 4:- get triggers configuration from "reg" in DT- add tables of triggers- sampling frequency is enable/disable when writing in trigger sampling_frequency attribute- no more use of interruptionsversion 3:- change compatible to "st,stm32-timer-trigger"- fix attributes access right- use string instead of int for master_mode and slave_mode- document device attributes in sysfs-bus-iio-timer-stm32version 2:- keep only one compatible- use st,input-triggers-names and st,output-triggers-names to know which triggers are accepted and/or create by the deviceSigned-off-by: Benjamin Gaignard Acked-by: Jonathan Cameron Signed-off-by: Lee Jones List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32
