Use the drm_bridge_connector_init() helper to create a drm_connector for
each output, instead of relying on the bridge drivers doing so. Attach
the bridges with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag to instruct
them not to create a connector.

Replace the manual panel handling with usage of the DRM panel bridge
helper. This simplifies the driver, and brings support for
DRM_BRIDGE_ATTACH_NO_CONNECTOR as an added bonus.

On all platforms except i.MX and Rockchip, the dw-hdmi DT bindings
require a video output port connected to an HDMI sink (most likely an
HDMI connector, in rare cases another bridges converting HDMI to another
protocol). For those platforms, retrieve the next bridge and attach it
from the dw-hdmi bridge attach handler.

Being informed of a failure to attach a bridge is useful, and many
drivers prints an error message in that case. Move the message to
drm_bridge_attach() to avoid code duplication.

The reference to the drm_device that was acquired by

When the system shuts down or warm reboots, the display may be active,

The Generic System Framebuffers support is built when the COMPILE_TEST
option is enabled. But this wrongly assumes that all the architectures
declare a struct screen_info.
This is true for most architectures, but at least the following do not:
arc, m68k, microblaze, openrisc, parisc and s390.
By attempting to make this compile testeable on all architectures, it
leads to linking errors as reported by the kernel test robot for parisc:
All errors (new ones prefixed by >>):
hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
(.init.text+0x24): undefined reference to `screen_info'
>> hppa-linux-ld: (.init.text+0x28): undefined reference to `screen_info'
To prevent these errors only allow sysfb to be built on systems that are
going to need it, which are x86 BIOS and EFI.
The EFI Kconfig symbol is used instead of (ARM || ARM64 || RISC) because
some of these architectures only declare a struct screen_info if EFI is
enabled. And also, because the SYSFB code is only used for EFI on these
architectures. For !EFI the "simple-framebuffer" device is registered by
OF when parsing the Device Tree Blob (if a DT node for this was defined).

Any interraction with the buffer pool (seeding a buffer, acquire one) is
made through a software portal (SWP, a DPIO object).
There are circumstances where the dpaa2-switch driver probes on a DPSW
before any DPIO devices have been probed. In this case, seeding of the
buffer pool will lead to a panic since no SWPs are initialized.
To fix this, seed the buffer pool after making sure that the software
portals have been probed and are ready to be used.

This simple series of commands:
ip link add br0 type bridge vlan_filtering 1
ip link set swp0 master br0
fails on sja1105 with the following error:
[ 33.439103] sja1105 spi0.1: vlan-lookup-table needs to have at least the default untagged VLAN
[ 33.447710] sja1105 spi0.1: Invalid config, cannot upload
Warning: sja1105: Failed to change VLAN Ethertype.
For context, sja1105 has 3 operating modes:
- SJA1105_VLAN_UNAWARE: the dsa_8021q_vlans are committed to hardware
- SJA1105_VLAN_FILTERING_FULL: the bridge_vlans are committed to hardware
- SJA1105_VLAN_FILTERING_BEST_EFFORT: both the dsa_8021q_vlans and the
bridge_vlans are committed to hardware
Swapping out a VLAN list and another in happens in
sja1105_build_vlan_table(), which performs a delta update procedure.
That function is called from a few places, notably from
sja1105_vlan_filtering() which is called from the
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING handler.
The above set of 2 commands fails when run on a kernel pre-commit
8841f6e63f2c ("net: dsa: sja1105: make devlink property
best_effort_vlan_filtering true by default"). So the priv->vlan_state
transition that takes place is between VLAN-unaware and full VLAN
filtering. So the dsa_8021q_vlans are swapped out and the bridge_vlans
are swapped in.
So why does it fail?
Well, the bridge driver, through nbp_vlan_init(), first sets up the
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING attribute, and only then
proceeds to call nbp_vlan_add for the default_pvid.
So when we swap out the dsa_8021q_vlans and swap in the bridge_vlans in
the SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING handler, there are no bridge
VLANs (yet). So we have wiped the VLAN table clean, and the low-level
static config checker complains of an invalid configuration. We _will_
add the bridge VLANs using the dynamic config interface, albeit later,
when nbp_vlan_add() calls us. So it is natural that it fails.
So why did it ever work?
Surprisingly, it looks like I only tested this configuration with 2
things set up in a particular way:
- a network manager that brings all ports up
- a kernel with CONFIG_VLAN_8021Q=y
It is widely known that commit ad1afb003939 ("vlan_dev: VLAN 0 should be
treated as "no vlan tag" (802.1p packet)") installs VID 0 to every net
device that comes up. DSA treats these VLANs as bridge VLANs, and
therefore, in my testing, the list of bridge_vlans was never empty.
However, if CONFIG_VLAN_8021Q is not enabled, or the port is not up when
it joins a VLAN-aware bridge, the bridge_vlans list will be temporarily
empty, and the sja1105_static_config_reload() call from
sja1105_vlan_filtering() will fail.
To fix this, the simplest thing is to keep VID 4095, the one used for
CPU-injected control packets since commit ed040abca4c1 ("net: dsa:
sja1105: use 4095 as the private VLAN for untagged traffic"), in the
list of bridge VLANs too, not just the list of tag_8021q VLANs. This
ensures that the list of bridge VLANs will never be empty.
Fixes: ec5ae61076d0 ("net: dsa: sja1105: save/restore VLANs using a delta commit method")

[Why]
Regression found in some embedded panels traces back to the earliest
upstreamed ASSR patch. The changed code flow are causing problems
with some panels.
[How]
- Change ASSR enabling code while preserving original code flow
as much as possible
- Simplify the code on guarding with internal display flag

DCN 3x increased Line buffer size for DCHUB latency hiding, from 4 lines
of 4K resolution lines to 5 lines of 4K resolution lines. All Line
Buffer can be used as extended memory for P State change latency hiding.
The maximum number of lines is increased to 32 lines. Finally,
LB_MEMORY_CONFIG_1 (LB memory piece 1) and LB_MEMORY _CONFIG_2 (LB
memory piece 2) are not affected, no change in size, only 3 pieces is
affected, i.e., when all 3 pieces are used in both LB_MEMORY_CONFIG_0
and LB_MEMORY_CONFIG_3 (for 4:2:0) modes.
