Subject: Re: [PATCH v2 00/17] Prepare the PowerQUICC QMC and TSA for the
 HDLC QMC driver

Hi Arnd,

As you suggested in the previous iteration [1], I sent a PR related to this
series:
  https://lore.kernel.org/all/20231212105514.273e8ab0@bootlin.com/

I didn't receive any feedback on this PR and it does not seem to have been
taken into account.
Did I miss something ?

Best regards,
Hervé
