These two PowerPC patches seem trivial enough and have got no response, unless someone objects I'll go ahead and apply them.

Ack. MAINTAINERS says: FREESCALE QUICC ENGINE LIBRARY M: Qiang Zhao <qiang.zhao@nxp.com> L: linuxppc-dev@lists.ozlabs.org S: Maintained F: drivers/soc/fsl/qe/ F: include/soc/fsl/qe/ But I see no email from that address since January 2021: https://lore.kernel.org/all/?q=f%3Aqiang.zhao%40nxp.com And actually drivers/soc/fsl was marked orphan in April, maybe this should be also. Or does Herve want to take over maintaining it? cheers

We had some discussion about that in April, see https://lore.kernel.org/linuxppc-dev/20240219153016.ntltc76bphwrv6hn@skbuf/T/#mf6d4a5eef79e8eae7ae0456a2794c01e630a6756 Hervé has some of our hardware for a limited period of time because he is doing some implementation for us, but he won't keep that hardware on the long run. I will send a patch to take over maintaining drivers/soc/fsl/ Christophe

qmc_chan_get_byphandle() and the resource managed version retrieve a channel from a simple phandle. Extend the API and introduce qmc_chan_get_byphandles_index() and the resource managed version in order to retrieve a channel from a phandle list using the provided index to identify the phandle in the list. Also update qmc_chan_get_byphandle() and the resource managed version to use qmc_chan_get_byphandles_index() and so avoid code duplication.
