From 3b050680c84153d8e6f5ae3785922cd417f4b071 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Wed, 13 Jan 2021 17:12:52 +1000
Subject: drm/nouveau/core: recognise GA10[024]

GA100 hidden behind a module option, as it's not been as well verified
since initial bring-up and may need additional changes.

There's no display anyway, so this can wait for a bit.

Subject: drm/nouveau/devinit/ga10[024]: initial support

VPLL regs changed a bit.  There's more stuff to do around these, but it's
less invasive to stick those changes into disp for now.

None of that belongs here anymore anyhow - fix that someday.

Subject: drm/nouveau/mc/ga10[024]: initial support

Fortunately, all the interrupts we need to bring up basic display support
are contained in a single leaf register, allowing this basic (but hackish)
implementation.

There's a bunch more invasive patches to come implementing all this in a
better/more complete way, but trying to get a minimal series out first.

Subject: drm/nouveau/disp/ga10[24]: initial support

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to
have been updated for use by the x86 VBIOS code, so we should be able to
continue using them for the moment.

Unfortunately, we require some hacks to do so, as the BeforeLinkTraining
IED script became a pointer to an array of scripts instead, without a
revbump of the relevant tables.

There's also some changes to SOR clock divider fiddling, which are
hopefully correct enough that things work as they should.

AFAIK, GA100 shouldn't have display, so it hasn't been added.
