updating old MediaTek DTs to add clock handles for the fixed clocks, and
going forward every new clock added to the binding would require even
more updates.

The commit also didn't update the example to match the changes, causing
additional warnings.

Instead let's keep the clocks optional so that old devicetrees can keep

usb: misc: Add onboard_usb_hub driver

The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.

Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.

Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

Committer notes:

previous patch using it:

    may return sys_perf_event_open failure with 3(No such process) if any of
    the process's threads die before we open the event. However, we want

perf inject: Adjust output data offset for backward compatibility

When 'perf inject' creates a new file, it reuses the data offset from
the input file. If there has been a change on the size of the header, as
happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
a corrupted output file.

This change adds the function perf_session__data_offset to compute the
data offset based on the current header size, and uses that instead of
the offset from the original input file.

using perf inject, there is no guarantee that the file on the current
machine at the current time has that build ID. Fix by comparing the
build IDs and skip adding to the cache if they are different.

Example:

  $ echo "int main() {return 0;}" > prog.c
  $ gcc -o prog prog.c
  $ perf record --buildid-all ./prog

 "Fixes for this week, bit larger than normal, but I think the last
  couple have been quieter, and it's only rc4.

  There are a lot of small msm fixes, and a slightly larger set of vc4
  fixes. The vc4 fixes clean up a lot of crashes around the rPI4
  hardware differences from earlier ones, and problems in the page flip
  and modeset code which assumed earlier hw, so I thought it would be
  okay to keep them in.

  Otherwise, it's a few amdgpu, i915, sun4i and a panel quirk.

  amdgpu:
   - Adjust GTT size logic
   - eDP fix for RMB
   - DCN 3.15 fix
   - DP training fix
   - Color encoding fix for DCN2+

  sun4i:
   - multiple suspend fixes

  vc4:
   - rework driver split for rpi4, fixes mulitple crashers.

  panel:
   - quirk for Aya Neo Next

  i915:
   - Revert low voltage SKU check removal to fix display issues
   - Apply PLL DCO fraction workaround for ADL-S
   - Don't show engine classes not present in client fdinfo

  msm:
   - Workaround for parade DSI bridge power sequencing
   - Fix for multi-planar YUV format offsets
   - Limiting WB modes to max sspp linewidth
   - Fixing the supported rotations to add 180 back for IGT
   - Fix to handle pm_runtime_get_sync() errors to avoid unclocked
     access in the bind() path for dpu driver
   - Fix the irq_free() without request issue which was a being hit
     frequently in CI.
   - Fix to add minimum ICC vote in the msm_mdss pm_resume path to
     address bootup splats
   - Fix to avoid dereferencing without checking in WB encoder
   - Fix to avoid crash during suspend in DP driver by ensuring
     interrupt mask bits are updated
   - Remove unused code from dpu_encoder_virt_atomic_check()
   - Fix to remove redundant init of dsc variable
   - Fix to ensure mmap offset is initialized to avoid memory corruption
     from unpin/evict
   - Fix double runpm disable in probe-defer path
   - VMA fenced-unpin fixes
