  1. arm64: dts: ipq6018: add pwm node

    Describe the PWM block on IPQ6018.
    
    The PWM is in the TCSR area. Make &tcsr "simple-mfd" compatible, and add
    &pwm as child of &tcsr.
    
    Add also ipq6018 specific compatible string.

  3. pwm: driver for qualcomm ipq6018 pwm block

    Driver for the PWM block in Qualcomm IPQ6018 line of SoCs. Based on
    driver from downstream Codeaurora kernel tree. Removed support for older
    (V1) variants because I have no access to that hardware.
    
    Tested on IPQ6010 based hardware.

  8. pwm: lpc18xx-sct: Simplify driver by not using pwm_[gs]et_chip_data()

    The per-channel data is available directly in the driver data struct. So
    use it without making use of pwm_[gs]et_chip_data().
    
    The relevant change introduced by this patch to lpc18xx_pwm_disable() at
    the assembler level (for an arm lpc18xx_defconfig build) is:
    
    	push    {r3, r4, r5, lr}
    	mov     r4, r0
    	mov     r0, r1
    	mov     r5, r1
    	bl      0 <pwm_get_chip_data>
    	ldr     r3, [r0, #0]
    
    changes to
    
    	ldr     r3, [r1, torvalds#8]
    	push    {r4, lr}
    	add.w   r3, r0, r3, lsl #2
    	ldr     r3, [r3, torvalds#92]   ; 0x5c
    
    So this reduces stack usage, has an improved runtime behavior because of
    better pipeline usage, doesn't branch to an external function and the
    generated code is a bit smaller occupying less memory.
    
    The codesize of lpc18xx_pwm_probe() is reduced by 32 bytes.

  9. pwm: lpc18xx-sct: Reduce number of devm memory allocations

    Each devm allocations has an overhead of 24 bytes to store the related
    struct devres_node additionally to the fragmentation of the allocator.
    So allocating 16 struct lpc18xx_pwm_data (which only hold a single int)
    adds quite some overhead. Instead put the per-channel data into the
    driver data struct and allocate it in one go.

  10. pwm: lpc18xx-sct: Initialize driver data and hardware before pwmchip_…

    …add()
    
    When a driver calls pwmchip_add() it has to be prepared to immediately
    get its callbacks called. So move allocation of driver data and hardware
    initialization before the call to pwmchip_add().
    
    This fixes a potential NULL pointer exception and a race condition on
    register writes.

  2. pwm: meson: Simplify duplicated per-channel tracking

     "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"

    torvalds committed Jan 23, 2022
  4. 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.

  5. perf evsel: Override attr->sample_period for non-libpfm4 events

    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.

  7. perf cpumap: Migrate to libperf cpumap api

    Switch from directly accessing the perf_cpu_map to using the appropriate
    libperf API when possible. Using the API simplifies the job of

  9. perf script: Fix printing 'phys_addr' failure issue

    Perf script was failed to print the phys_addr for SPE profiling.
    One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
    attribute set, perf script then exits with error.
    
    Now referring to 'addr', use evsel__do_check_stype() to check the type.
    
    Before:
    
      # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
    		store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
      # perf script -F pid,tid,addr,phys_addr
      Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.
    
    After:
    
      # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
    		store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
      # perf script -F pid,tid,addr,phys_addr
      4064384/4064384 ffff802f921be0d0      2f921be0d0
      4064384/4064384 ffff802f921be0d0      2f921be0d0
