For reference, this should be "PCI" and "ID", but I can fix those up
while applying.

Also, it's customary to include a changelog in subsequent versions of a
patch, as well as change the subject prefix to include the patch version
number. That makes it easier for other people to track things.

You can do so using:

	$ git format-patch --subject-prefix='PATCH v2' ...

The changelog typically goes below the --- marker (the one below the
Signed-off-by line) and would look something like this:

---
Changes in v2:
- keep board information table sorted by device ID
- reuse Braswell board information

Again, no need to resend this time, but something to keep in mind for
future patches.

I'd prefer a proper spelling of your name. Would "Qipeng Zha" be
correct?

Looks like I never got around to applying this. Done now.

Please keep these sorted by device id.

I wonder if we can just reuse pwm_lpss_bsw_info for now as the clock
rate is the same, no?
