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 defined in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger function could be used to check if the trigger is valid or not. "trgo" trigger have a "sampling_frequency" attribute which allow to configure timer sampling frequency. version 8: - change kernel version from 4.10 to 4.11 in ABI documentation version 7: - remove all iio_device related code - move driver into trigger directory version 5: - simplify tables of triggers - only create an IIO device when needed version 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 interruptions version 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-stm32 version 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 device Signed-off-by: Benjamin Gaignard Acked-by: Jonathan Cameron Signed-off-by: Lee Jones --- .../ABI/testing/sysfs-bus-iio-timer-stm32 | 29 ++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-timer-stm32 (limited to 'Documentation/ABI') diff --git a/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32 b/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32 new file mode 100644 index 000000000000..6534a60037ff --- /dev/null +++ b/Documentation/ABI/testing/sysfs-bus-iio-timer-stm32 @@ -0,0 +1,29 @@ +What: /sys/bus/iio/devices/triggerX/master_mode_available +KernelVersion: 4.11 +Contact: benjamin.gaignard@st.com +Description: + Reading returns the list possible master modes which are: + - "reset" : The UG bit from the TIMx_EGR register is used as trigger output (TRGO). + - "enable" : The Counter Enable signal CNT_EN is used as trigger output. + - "update" : The update event is selected as trigger output. + For instance a master timer can then be used as a prescaler for a slave timer. + - "compare_pulse" : The trigger output send a positive pulse when the CC1IF flag is to be set. + - "OC1REF" : OC1REF signal is used as trigger output. + - "OC2REF" : OC2REF signal is used as trigger output. + - "OC3REF" : OC3REF signal is used as trigger output. + - "OC4REF" : OC4REF signal is used as trigger output. + +What: /sys/bus/iio/devices/triggerX/master_mode +KernelVersion: 4.11 +Contact: benjamin.gaignard@st.com +Description: + Reading returns the current master modes. + Writing set the master mode + +What: /sys/bus/iio/devices/triggerX/sampling_frequency +KernelVersion: 4.11 +Contact: benjamin.gaignard@st.com +Description: + Reading returns the current sampling frequency. + Writing an value different of 0 set and start sampling. + Writing 0 stop sampling. -- cgit v1.2.1 From 1dc2af87877dd43e6874ef331974505df63378e7 Mon Sep 17 00:00:00 2001 From: Andreas Klinger Date: Wed, 25 Jan 2017 20:07:47 +0100 Subject: iio: distance: srf08: add driver ABI documentation Add sysfs-bus-iio-distance-srf08 for individual attributes of the driver, especially: - sensitivity which the device documentation calls gain for amplifying the signal - max_range for limiting the maximum distance for expected echos and therefore limiting the time waiting for telegrams Signed-off-by: Andreas Klinger Signed-off-by: Jonathan Cameron --- .../ABI/testing/sysfs-bus-iio-distance-srf08 | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 (limited to 'Documentation/ABI') diff --git a/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 b/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 new file mode 100644 index 000000000000..0a1ca1487fa9 --- /dev/null +++ b/Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 @@ -0,0 +1,22 @@ +What /sys/bus/iio/devices/iio:deviceX/sensor_sensitivity +Date: January 2017 +KernelVersion: 4.11 +Contact: linux-iio@vger.kernel.org +Description: + Show or set the gain boost of the amp, from 0-31 range. + default 31 + +What /sys/bus/iio/devices/iio:deviceX/sensor_max_range +Date: January 2017 +KernelVersion: 4.11 +Contact: linux-iio@vger.kernel.org +Description: + Show or set the maximum range between the sensor and the + first object echoed in meters.
