Convert the mxsfb binding to YAML. The deprecated binding is dropped, as
neither the DT sources nor the driver support it anymore. The converted
binding is named fsl,lcdif.yaml to match the usual bindings naming
scheme.
The compatible strings are messy, and DT sources use different kinds of

- Reworked the DT
When get_vaddr_frames() does its hacky follow_pfn() loop it should never
be allowed to extract a struct page from a normal VMA. This could allow a
serious use-after-free problem on any kernel memory.
Restrict this to only work on VMA's with one of VM_IO | VM_PFNMAP
set. This limits the

This patch series attempts to add support for a DP-HDMI2.1 Protocol
Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata
E5 to DisplayPort_v2.0:
https://vesa.org/join-vesamemberships/member-downloads/?action=stamp=42299
The details are mentioned in DP to HDMI2.1 PCON Enum/Config
This patch calls functions to check FRL training requirements

The call is made before the DP link training. In case FRL is not
required or failure during FRL training, the TMDS mode is selected
for the pcon.

HDMI2.1 PCON advertises Max FRL bandwidth supported by the PCON and

This patch adds support for link status and link recovery. There
are specific DPCD’s defined for link status check and recovery in
case of any issues. PCON will communicate the same using an IRQ_HPD
to source. HDMI sink would have indicated the same to PCON using
SCDC
This patch adds functions to start FRL training for an HDMI2.1 sink,
connected via a PCON as a DP branch device.
This patch also adds a new structure for storing frl training related
data, when FRL training is completed.

In this patch enabled support for link status and recovery in i915
driver. HDMI link loss indication to upstream DP source is indicated
via IRQ_HPD. This is followed by reading of HDMI link configuration
status (HDMI_TX_LINK_ACTIVE_STATUS). If the PCON → HDMI 2.1 link status

Drop issues already resolved in vkms:
- CRC API Improvements to [1] add igt test to check extreme alpha values
and [2] alpha blending;
- [3] prime buffer sharing;
