It appears that MSI does not work on either G5 PPC nor on a E5500-based
platform, where other hardware is reported to work fine with MSI.
Both tests were conducted with NV4x hardware, so perhaps other (or even
this) hardware can be made to work. It's still possible to force-enable
with config=NvMSI=1 on load.

drm_crtc_init exposes the XRGB8888 and ARGB8888 formats. In actuality,
ARGB8888's 32-bit depth messes up some formulas that weren't meant for
it, and the alpha is fairly meaningless for the primary plane.
The modesetting logic appears to be fully prepared for RGB565 as well as
XRGB1555 however, as tested with modetest.

We were previously setting the pitch based on a perfectly packed buffer.
This does not necessarily happen. Either modetest started generating
such buffers recently, or earlier testing only happened with well-picked
overlay sizes.
While we're at it, beef up and refactor the error state detection.

Pre-nv50 YUV overlays have stringent requirements for working with the
internal machinery. Instead of rejecting these at update_plane time, we
should instead prevent the framebuffers from being created in the first
place.

Forked from GP107 implementation. Secboot/gr left out as we don't have
signed blobs from NVIDIA in linux-firmware.
(Ben): Was unable to mmiotrace the binary driver for unknown reasons,
so not able to 100% confirm that no other changes from GP107
are needed. Quick testing shows it seems to work well enough
for display. Due to NVIDIA dragging their heels on getting
signed firmware to us, this is the best we can do for now.

Most of these errors seem to be WFD related. Official documentation
says dcb type 8 is reserved. It's probably used for WFD. Silence
the warning in either case.
Connector type 70 is stated to be a virtual connector for WiFi
display. Since we know this, don't warn that we don't.

- Enable color space conversion on the primary plane when the framebuffer

- The IPUv3 base driver now uses drm_format_info in the PRE/PRG code. The
PRE/PRG parts are already disabled if DRM is not available. Enforce that

For asynchronous operation, SGs are allocated without a page mapped to
them or with a page that is not used (ref-counted). If the SGL is freed,
the code must only call put_page for an SG if there was a page assigned

Commit 9ae433bc79f9 ("crypto: chacha20 - convert generic and x86 versions
to skcipher") ported the existing chacha20 code to use the new skcipher
API, and introduced a bug along the way. Unfortunately, the tcrypt tests
did not catch the error, and it was only found recently by Tobias.
Stefan kindly diagnosed the error, and proposed a fix which is similar
to the one below, with the exception that 'walk.stride' is used rather
than the hardcoded block size. This does not actually matter in this
case, but it's a better example of how to use the skcipher walk API.

Using sg_miter_start and sg_miter_next, the buffer of an SG is kmap'ed
to *buff. The current code calls sg_miter_stop (and thus kunmap) on the
SG entry before the last access of *buff.
The patch moves the sg_miter_stop call after the last access to *buff to
ensure that the memory pointed to by *buff is still mapped.

On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires
two clocks instead of one.
On all Allwinner SoCs that share the common USB PHY design supported by
the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there
is at most one HSIC PHY, typically the last.
In this patch we take advantage of these known constraints and store an
index in the compatible-string-related config structure describing which
PHY is HSIC, needing the extra hsic_12M clock.

When building the kernel for Sparc using gcc 7.x, the build fails
with:
arch/sparc/kernel/pcic.c: In function ‘pcibios_fixup_bus’:
arch/sparc/kernel/pcic.c:647:8: error: ‘cmd’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
cmd |= PCI_COMMAND_IO;
^~
The simplified code looks like this:
unsigned int cmd;
[...]
pcic_read_config(dev->bus, dev->devfn, PCI_COMMAND, 2, &cmd);
[...]
cmd |= PCI_COMMAND_IO;
I.e, the code assumes that pcic_read_config() will always initialize
cmd. But it's not the case. Looking at pcic_read_config(), if
bus->number is != 0 or if the size is not one of 1, 2 or 4, *val will
not be initialized.
As a simple fix, we initialize cmd to zero at the beginning of
pcibios_fixup_bus.
