      Update the Icicle Kit device tree · f9a8f627

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].

[3] https://lore.kernel.org/linux-riscv/cover.1639744106.git.geert@linux-m68k.org/

Changes from v3:
- drop "mailbox: change mailbox-mpfs compatible string", already upstream:
  commit f10b1fc0
- fix copy paste error in microchip,mpfs-mailbox dt-binding
- remove whitespace in syscontroller dt entry

Changes from v2:
- dropped plic int header & corresponding defines in dts{,i}
- use $ref to drmode in mpfs-musb binding
- split changes to dts{,i} again: functional changes to existing
  elements now are in a new patch
- drop num-cs property in mpfs-spi binding
- dont make the system controller a simple-mfd
- move the separate bindings for rng/generic system services into the
  system controller binding
- added an instance corei2c as i2c2 in the fabric dtsi
- add version numbering to corepwm and corei2c compat string (-rtl-vN)

      spi: add new SoC mt8186 support for spi-mtk-nor · 5566ccc5
      Mark Brown authored 
      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.

      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"

      ftrace: Fix assuming build time sort works for s390 · 6b9b6413
      Steven Rostedt (Google) authored 
      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.
