Some ACPI nodes may have more than one Spi Resource. To be able to handle these case, its necessary to have a way of counting these resources.

This one is pretty straight forward to switch over, the driver already relies on inspecting cs_gpio just check cs_gpiod instead and stop the special handling of requesting the GPIO and stuff the core will take care of.

This switches the ST SSC SPI controller to use GPIO descriptors from the core instead of GPIO numbers. It is already using the core parsing of GPIO numbers so the switch is pretty straight-forward.

This driver is already relying on the core to provide valid GPIO numbers in spi->cs_gpio through of_spi_get_gpio_numbers(), so we can switch to letting the core use GPIO descriptors instead. The driver was assigning a local function to the custom chipselect callback, but I chose to just open code the gpiod setting instead, this is easier to read. The only platform that overrides the cs_control callback is the mpc832x_rdb.

This converts the PXA2xx SPI driver to use GPIO descriptors exclusively to retrieve GPIO chip select lines. The device tree and ACPI paths of the driver already use descriptors, hence ->use_gpio_descriptors is already set and this codepath is well tested. Convert all the PXA boards providing chip select GPIOs as platform data and drop the old GPIO chipselect handling in favor of the core managing it exclusively.

Merge series from conor.dooley@microchip.com <conor.dooley@microchip.com> Conor Dooley <conor.dooley@microchip.com>: From: Conor Dooley <conor.dooley@microchip.com> This series updates the Microchip Icicle Kit device tree by adding a host of peripherals, and some updates to the memory map. In addition, the device tree has been split into a third part, which contains "soft" peripherals that are in the fpga fabric. Several of the entries are for peripherals that have not get had their drivers upstreamed, so in those cases the dt bindings are included where appropriate in order to avoid the many "DT compatible string <x> appears un-documented" errors. Depends on mpfs clock driver series [1] to provide: dt-bindings/clock/microchip,mpfs-clock.h and on the other changes to the icicle/mpfs device tree from geert that are already in linux/riscv/for-next. Additionally, the interrupt-extended warnings on the plic/clint are cleared by [2] & [3].

Merge series from guochun.mao@mediatek.com <guochun.mao@mediatek.com>: These patches is mainly for adding mt8186 support. The spi nor controller of mt8186 has some differences, it needs one more clk, axi_s, for dma feature. And also needs one extra dummy bit when read flash registers.

This driver has a bunch of custom oldstyle GPIO number-passing fields and a custom set-up callback. The good thing is: nothing in the kernel is using it. Convert the driver to use GPIO descriptors with a SPI_MASTER_GPIO_SS flag so that the local CS callback also get invoked as the hardware needs this. New users of this driver can provide GPIO descriptor tables like the other converted drivers.

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.

Add a test for aliases with hyphens in the name to ensure that the pmu-events tables are as expects. There should be no reason why these sort of aliases would be treated differently, but no harm in checking.

Event aliasing for events whose name in the form foo-bar-baz is not supported, while foo-bar, foo_bar_baz, and other combinations are, i.e. two hyphens are not supported. The HiSilicon D06 platform has events in such form: $ ./perf list sdir-home-migrate List of pre-defined events (to be used in -e): uncore hha: sdir-home-migrate [Unit: hisi_sccl,hha] $ sudo ./perf stat -e sdir-home-migrate event syntax error: 'sdir-home-migrate' \___ parser error Run 'perf list' for a list of valid events Usage: perf stat [<options>] [<command>] -e, --event <event>event selector. use 'perf list' to list available events To support, add an extra PMU event symbol type for "baz", and add a new rule in the bison file.

A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
