Please ignore this one, I've send out the wrong version without Daniels

The interesting one in this series is the last patch.

Hi everyone,
hopefully the last iteration of those patches.
For now I've addressed the issue of unmapping imported BOs from the amdgpu page
tables immediately by locking the page tables in place.
For HMM handling we are getting the ability to invalidate BOs without locking
the VM anyway, so
On the exporter side we add optional explicit pinning callbacks. Which are
called when the importer doesn't implement dynamic handling, move notification
or need the DMA-buf locked in place for its use case.
On the importer side we add an optional move_notify callback. This callback is
used by
Avoid that we ping/pong the buffers when we stop to pin DMA-buf
exports by using the allowed domains for exported buffers.

Instead of defining KVMGT per-device state in struct intel_vgpu

what state KVMGT needs to keep.

Hi James,
Thank you for the review.
Did you intentionally review patches from the v4 series or you simply
didn't notice the v5? There are some differences, the most notable one
is using proper way of subclassing a drm_framebuffer.
The v5 series was sent on 17th December 2019.

SoCs that have multiple TCONs can use the two set of pins on the first TCON
to drive a dual-link display. Add a property to enable the dual link.

Some LVDS encoders in the Allwinner SoCs can output on a dual-link. Let's
add a DT property to toggle it.

If the panel interface is 24-bit but our primary plane is 16bpp,
configure as if the panel was 18-bit. This tricks permits the display
of 16bpp data on a 24-bit panel by wiring each color component to the
MSBs of the 24-bit interface.

There is a ACT8600 on the CI20 board and the bindings of the
ACT8865 driver have changed without updating the CI20 device
tree. Therefore the PMU can not be probed successfully and
is running in power-on reset state.
Fix DT to match the latest act8865-regulator bindings.

Some LVDS encoders can support multiple polarities on the data and
clock lanes, and similarly some panels require a given polarity on
their inputs. Add a property on the panel to configure the encoder
properly.

The fbdev emulation is only ever used on Ingenic SoCs to run old SDL1
based games at 16bpp (rgb565). Recent applications generally talk to
DRM directly, and can request their favourite pixel format; so we can
make everybody happy by switching the emulated fbdev to 16bpp.

We need to make sure that the DRM driver is fully registered before
allowing the panel to be attached. Otherwise, we may trigger a hotplug
event before sun4i_framebuffer_init() sets up drm->mode_config.funcs,
causing a NULL pointer dereference.
