Taniya Das a764e1ed50 dt-bindings: clock: Add YAML schemas for CAMCC clocks on SC7280
The camera clock controller clock provider have a bunch of generic
properties that are needed in a device tree. Add the CAMCC clock IDs for
camera client to request for the clocks.

Shawn Guo 36354c32bd clk: qcom: smd-rpm: Add .recalc_rate hook for clk_smd_rpm_branch_ops
As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock.  This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.

To get this work, XO buffered clocks need the following updates.

- Assign a correct rate rather than the fake one which is being used to
  generate binary value for clk_smd_rpm_req interface.

- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
  clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

Linus Torvalds b5b65f1398 perf tools changes for v5.15: 2nd batch
- Add missing fields and remove some duplicate fields when printing a perf_event_attr.
 
 - Fix hybrid config terms list corruption.
 
 - Update kernel header copies, some resulted in new kernel features being
   automagically added to 'perf trace' syscall/tracepoint argument id->string translators.
 
 - Add a file generated during the documentation build to .gitignore.
 
 - Add an option to build without libbfd, as some distros, like Debian consider
   its ABI unstable.
 
 - Add support to print a textual representation of IBS raw sample data in 'perf report'.
 
 - Fix bpf 'perf test' sample mismatch reporting
 
 - Fix passing arguments to stackcollapse report in a 'perf script' python script.
 
 - Allow build-id with trailing zeros.
 
 - Look for ImageBase in PE file to compute .text offset.

Linus Torvalds d8e988b62f Misc driver fix for 5.15-rc1
Here is a single patch for 5.15-rc1, for the lkdtm misc driver.
 
 It resolves a build issue that many people were hitting with your
 current tree, and Kees and others felt would be good to get merged
 before -rc1 comes out, to prevent them from having to constantly hit it
 as many development trees restart on -rc1, not older -rc releases.
 
 It has NOT been in linux-next, but has passed 0-day testing and looks
 "obviously correct" when reviewing it locally :)

Merge tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6

Pull smbfs updates from Steve French:
 "cifs/smb3 updates:

   - DFS reconnect fix

   - begin creating common headers for server and client

   - rename the cifs_common directory to smbfs_common to be more
     consistent ie change use of the name cifs to smb (smb3 or smbfs is
     more accurate, as the very old cifs dialect has long been
     superseded by smb3 dialects).

  In the future we can rename the fs/cifs directory to fs/smbfs.

  This does not include the set of multichannel fixes nor the two
  deferred close fixes (they are still being reviewed and tested)"

* tag '5.15-rc-cifs-part2' of git://git.samba.org/sfrench/cifs-2.6:
  cifs: properly invalidate cached root handle when closing it
  cifs: move SMB FSCTL definitions to common code
  cifs: rename cifs_common to smbfs_common
  cifs: update FSCTL definitions
