b01ced2b - iio: trigger: Add STM32 LPTimer trigger driver

Mon, 28 Aug 2017 10:04:11 +0000

iio: trigger: Add STM32 LPTimer trigger driverAdd support for LPTIMx_OUT triggers that can be found on some STM32devices. These triggers can be used then by ADC or DAC.Typical usage is to configure LPTimer as PWM output (via pwm-stm32-lp)and have synchronised analog conversions with these triggers.Signed-off-by: Fabrice Gasnier Reviewed-by: Jonathan Cameron Signed-off-by: Lee Jones List of files: /linux-6.15/drivers/iio/trigger/Kconfig

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/drivers/iio/trigger/Kconfig

bc2e1126 - iio:trigger: Experimental kthread tight loop trigger (thread only)

Sun, 06 Mar 2016 20:02:56 +0000

iio:trigger: Experimental kthread tight loop trigger (thread only)This patch is in response to that ofGregor Boirie who proposed using a tight kthread within a device driver (be it with thesupport factored out into a helper library) in order to basically spin asfast as possible.It is meant as a talking point rather than a formal proposal of the code(though we are heading towards that I think).Also gives people some working code to mess around with.I proposed that this could be done with a trigger with a few constraintsand this is the proof (be it ugly) of that.There are some constraints though, some of which we would want to relaxif this were to move forward.* Will only run the thread part of the registered pollfunc. This is to avoid the overhead of jumping in and out of interrupt context. Is the overhead significant? Not certain but feels like it should be!* This limitation precludes any device that 'must' do some work in interrupt context. However, that is true of few if any drivers and I suspect that any that do will be restricted to using triggers they provide themselves. Usually we have a top half mainly to grab a timestamp as soon after the dataready type signal as possible.Signed-off-by: Jonathan Cameron Acked-by: Daniel Baluta List of files: /linux-6.15/drivers/iio/trigger/Kconfig

ac5006a2 - iio: trigger: Introduce IIO hrtimer based trigger

Mon, 09 Nov 2015 07:14:01 +0000

iio: trigger: Introduce IIO hrtimer based triggerThis patch registers a new IIO software trigger interrupt sourcebased on high resolution timers.Notice that if configfs is enabled we create sampling_frequencyattribute allowing users to change hrtimer period (1/sampling_frequency).The IIO hrtimer trigger has a long history, this patch is based onan older version from Marten and Lars-Peter.Signed-off-by: Marten Svanfeldt Signed-off-by: Lars-Peter Clausen Signed-off-by: Daniel Baluta Signed-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/trigger/Kconfig

3edc84e6 - iio: Add a comment to about alphabetical order to Kconfigs and Makefiles

Mon, 15 Jul 2013 07:45:00 +0000

iio: Add a comment to about alphabetical order to Kconfigs and MakefilesKeeping Makefile and Kconfig entries in alphabetical order usually works betterthan just appending new entries at the end, since it reduces the amount ofconflicts. This patch adds a comment to the IIO Kconfig and Makefile files todocument that the entries should be kept in alphabetical order.Also reorder those entries which weren't in alphabetical order yet.Signed-off-by: Lars-Peter Clausen Signed-off-by: Jonathan Cameron List of files: /linux-6.15/drivers/iio/trigger/Kconfig
