b59dcca97b dt-bindings: display: ti,am65x-dss: Add support for common1 region 
TI keystone display subsystem present in AM65, AM62 and AM62A SoC support
two separate register spaces namely "common" and "common1" which can be
used by two separate hosts to program the display controller as described
in respective Technical Reference Manuals [1].

The common1 register space has similar set of configuration registers as
supported in common register space except the global configuration
registers which are exclusive to common region.

This adds binding for "common1" register region too as supported by the
hardware.

42328003ec accel/ivpu: Refactor BO creation functions 
Rename BO allocate/create functions, so the code is more consistent.
There are now two matching buffer creation functions:
  - ivpu_bo_create_ioctl() - create a BO from user space
  - ivpu_bo_create() - create a BO from kernel space

ivpu_bo_alloc() is now only used to allocate struct ivpu_bo which better
matches its name.

1a9e51bef8 drm/meson: improve encoder probe / initialization error handling 
Rename meson_encoder_{cvbs,dsi,hdmi}_init() to
meson_encoder_{cvbs,dsi,hdmi}_probe() so it's clear that these functions
are used at probe time during driver initialization. Also switch all
error prints inside those functions to use dev_err_probe() for
consistency.

This makes the code more straight forward to read and makes the error
prints within those functions consistent (by logging all -EPROBE_DEFER
with dev_dbg(), while actual errors are logged with dev_err() and get
the error value printed).

8084a5b589 fbdev/efifb: Remove framebuffer relocation tracking 
If the firmware framebuffer has been reloacted, the sysfb code
fixes the screen_info state before it creates the framebuffer's
platform device. Efifb will automatically receive a screen_info
with updated values. Hence remove the tracking from efifb.

78aa89d1df firmware/sysfb: Update screen_info for relocated EFI framebuffers 
On ARM PCI systems, the PCI hierarchy might be reconfigured during
boot and the firmware framebuffer might move as a result of that.
The values in screen_info will then be invalid.

Work around this problem by tracking the framebuffer's initial
location before it get relocated; then fix the screen_info state
between reloaction and creating the firmware framebuffer's device.

This functionality has been lifted from efifb. See the commit message
of commit 55d728a40d ("efi/fb: Avoid reconfiguration of BAR that
covers the framebuffer") for more information.

4e754597d6 firmware/sysfb: Create firmware device only for enabled PCI devices 
Test if the firmware framebuffer's parent PCI device, if any, has
been enabled. If not, the firmware framebuffer is most likely not
working. Hence, do not create a device for the firmware framebuffer
on disabled PCI devices.

So far, efifb tracked the status of the PCI parent device internally
and did not bind if it was disabled. This patch implements the
functionality for all PCI-based firmware framebuffers.

75fa9b7e37 video: Add helpers for decoding screen_info 
The plain values as stored in struct screen_info need to be decoded
before being used. Add helpers that decode the type of video output
and the framebuffer I/O aperture.

Old or non-x86 systems may not set the type of video directly, but
only indicate the presence by storing 0x01 in orig_video_isVGA. The
decoding logic in screen_info_video_type() takes this into account.
It then follows similar code in vgacon's vgacon_startup() to detect
the video type from the given values.

A call to screen_info_resources() returns all known resources of the
given screen_info. The resources' values have been taken from existing
code in vgacon and vga16fb. These drivers can later be converted to
use the new interfaces.

v2:
	* return ssize_t from screen_info_resources()
	* don't call __screen_info_has_lfb() unnecessarily

0d192c4c72 dt-bindings: display: rockchip: rockchip,dw-hdmi: remove port property 
The hdmi-connector nodes are now functional and the new way to model
hdmi ports nodes with both in and output port subnodes. Unfortunately
with the conversion to YAML the old method with only an input port node
was used. Later the new method was also added to the binding.
A binding must be unambiguously, so remove the old port property
entirely and make port@0 and port@1 a requirement as all
upstream dts files are updated as well and because checking
deprecated stuff is a bit pointless.
Update the example to avoid use of the removed property.
