I should have let this soak for a while in linux-next, since we have at
least one board that hit a regression from it. Revert from 4.20-rc, and
we'll queue it for next merge window once regression is fixed.
This reverts commit 513eb98595522bc0cb83831a9daee1d5738e66f1.

The "official" Condor boards have always been wired to mount NFS via
GEther, not EtherAVB -- the boards resoldered for EtherAVB were local
to Cogent Embedded, so we've been having an unpleasant situation where
a "normal" Condor board still can't mount NFS (unless an EtherAVB PHY
extension board is plugged in). Switch from EtherAVB to GEther at last!

The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound. The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound. When an audio client is registered
after that point, it would miss the gpu_bound call. This leads to the
unexpected lack of runtime PM in HD-audio side.
For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

VGEM doesn't do anything modeset specific, so in a way exposing a
primary node is 'wrong'. At the same time, we extensively use if for
creating dumb buffers, fences, prime fd <> handle imports/exports.
To the point that we explicitly annotate the vgem fence ioctls as
DRM_RENDER_ALLOW and have an IGT test which opens the render node.
close(drm_open_driver_render(DRIVER_VGEM))
Better late than never, let's flip the switch.

H6 has Synopsys DWC HDMI 2.0 TX PHY.
There is no freely available documentation for it, only code found in
BSP kernel. However, judging by the code, PHY is very similar to older
Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem
to be the same.
According to i.MX6 documentation, mpll settings are based on pixel clock
and are not specific to each SoC. Because of that, mpll table in this
commit is based on that documentation and not on BSP code. Other PHY
settings were derived from BSP PHY driver code.

Currently sun8i-hdmi-phy driver supports only custom PHYs connected to
DW HDMI controller. Since newest Allwinner SoCs have unmodified Synopsys
PHY, driver has to be reorganized to support them.
Variant structure is expanded to allow differentiation between custom
and Sysnopsys PHYs and to hold Synopsys PHY settings.
Since DW HDMI bridge platform data has different fields for custom and
Sysnopsys PHY, function sun8i_hdmi_phy_get_ops() is replaced with
sun8i_hdmi_phy_set_ops().

I noticed during the creation of another bugfix that the BCH_CONST_PARAMS
option that is set by DOCG3 breaks setting variable parameters for any
other users of the BCH library code.
The only other user we have today is the MTD_NAND software BCH
implementation (most flash controllers use hardware BCH these days
and are not affected). I considered removing BCH_CONST_PARAMS entirely
because of the inherent conflict, but according to the description in
lib/bch.c there is a significant performance benefit in keeping it.
To avoid the immediate problem of the conflict between MTD_NAND_BCH
and DOCG3, this only sets the constant parameters if MTD_NAND_BCH
is disabled, which should fix the problem for all cases that
are affected. This should also work for all stable kernels.
Note that there is only one machine that actually seems to use the
DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have
the driver disabled, but it almost certainly shows up if we wanted
to test random kernels on machines that use software BCH in MTD.

This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b
This patch makes it to need get_vblank_counter callback in crtc
to get frame counter from decon driver.
However, drm_dev->max_vblank_count is a member unique to
vendor's DRM driver but in case of ARM DRM, some CRTC devices
don't provide the frame counter value. As a result, this patch
made extension and clone mode not working.
Instead of this patch, we may need separated max_vblank_count
which belongs to each CRTC device, or need to implement frame
counter emulation for them who don't support HW frame counter.

The NPU IOMMU is setup to mirror the parent PCIe device IOMMU
setup. Therefore it does not make sense to call dma operations such as
dma_map_page(), etc. directly on these devices. The existing dma_ops
simply print a warning if they are ever called, however this is
unnecessary and the warnings are likely to go unnoticed.
It is instead simpler to remove these operations and let the generic
DMA code print warnings (eg. via a NULL pointer deref) in cases of
buggy drivers attempting dma operations on NVLink devices.

Bindings for "fixed-regulator" only explicitly support "gpio" property,
not "gpios". Fix by correcting the property name.
The enet PHYs on imx6sx-sdb needs to be explicitly reset after a power
cycle, this can be handled by the phy-reset-gpios property. Sadly this
is not handled on suspend: the fec driver turns phy-supply off but
doesn't assert phy-reset-gpios again on resume.
Since additional phy-level work is required to support powering off the
phy in suspend fix the problem by just marking the regulator as
"boot-on" "always-on" so that it's never turned off. This behavior is
equivalent to older releases.
Keep the phy-reset-gpios property on fec anyway because it is a correct
description of board design.
This issue was exposed by commit efdfeb079cc3 ("regulator: fixed:
Convert to use GPIO descriptor only") which causes the "gpios" property
to also be parsed. Before that commit the "gpios" property had no
effect, PHY reset was only handled in the the bootloader.
This fixes linux-next boot failures previously reported here:

A quoted label reference doesn't expand to the node path and is taken as
a literal string. Dropping the quotes can fix this unless the baudrate
string is appended in which case we have to use the alias.
At least on VF610, the problem was masked by setting the console in
bootargs. Use the alias syntax with baudrate parameter so we can drop
setting the console in bootargs.
