Probably not, but afterwards you sent your series which moves the driver into drivers/gpio/ and which does the same, so this one was flagged "superseeded" in Patchwork (https://patchwork.ozlabs.org/project/linuxppc-dev/patch/[email protected]/)
I put it back to 'new'. Maddy, can you pick it up ? Christophe
