Sorry Tomasz, I must have mistakenly marked this "accepted" in
patchwork, so it fell off my to-do list. It's too late to get this in
v4.11, but I can still apply it for v4.12.
I put it on my pci/host-thunder branch with Robert's ack. I added a preceding
patch to tidy up whitespace, which makes this patch look like just:
/* SoC pass2.x */
THUNDER_PEM_QUIRK(1, 0),
THUNDER_PEM_QUIRK(1, 1),
+ THUNDER_ECAM_QUIRK(1, 10),
Please double-check it to make sure this is what you need.
