Initially this was designed to: | Fix sleeping in atomic context warning and a deadlock after iio_trigger_poll() | call | | If iio_trigger_poll() is called after IRQ was disabled, we will call | reenable_trigger() directly from hard IRQ or hrtimer context instead of | IRQ thread. In this case we will run in to multiple issue as sleeping in atomic | context and a deadlock. | | To avoid this issue, rework the trigger to use state machine. All state | changes are done over the hrtimer, so it allows us to drop fsleep() and | avoid the deadlock. Since this issue was fixed by: 9020ef65 ("iio: trigger: Fix a scheduling whilst atomic issue seen on tsc2046"). This patch is a cleanup to make state machine easier to follow. Signed-off-by:

This patch makes I2C and SPI interface drivers for STMicroelectronics sensor chips individually selectable via Kconfig. The default is kept unchanged - I2C and SPI interface drivers are still selected by default if the corresponding bus support is available. However, the patch makes it possible to explicitly disable drivers that are not needed for a particular target. Signed-off-by:

Before adding new Semtech sensors, move common logic to all Semtech SAR sensor in its own file: - interface with IIO subsystem, - interrupt management, - channel access conrol, - event processing. The change adds a bidirectional interface between sx93xx and sx_common. The change is quite mechanical, as the impacted functions are moved and renamed. Signed-off-by:

Pull ftrace fix from Steven Rostedt: "Fix s390 breakage from sorting mcount tables. The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things. Add a new config to tell the boot if the mcount table is sorted or not, and allow s390 to opt out of it" * tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.
