Here's the eagerly-awaited fix to unblock T720/T820, plus a couple of
other bits that I've collected so far. I'm not considering this as
5.3 fixes material, but it would be nice if there's any chance still
to sneak it into 5.4.

Robin.

I hope this will be part of v5.4 so we can run panfrost on vanilla v5.4 !

Not a chance -- the merge window opens on Monday and -next isn't being
rolled out at the moment due to LPC. Let's shoot for 5.5 and get this
queued up in a few weeks.

Fair enough, that was certainly more extreme optimism than realistic
expectation on my part :)

There is some argument for taking #1 and #2 as 5.4 fixes, though - the
upcoming Mesa 19.2 release will enable T820 support on the userspace side -
so let's pick that discussion up again in a few weeks.

Ok, I'll include those two in my fixes pull to Joerg at -rc1.

Hi Will,

Looks like this didn't end up happening?

Thanks,

Tomeu
