There is little harm in ignoring fractional coordinates
(they just get truncated).
Without this:
modetest -M vc4 -F tiles,gradient -s 32:1920x1080-60 -P89@74:1920x1080*.1.1@XR24
is rejected. We have the same issue in Kodi when trying to
use zoom options on video.
Note: even if all coordinates are fully integer. e.g.
src:[0,0,1920,1080] dest:[-10,-10,1940,1100]
it will still get rejected as drm_atomic_helper_check_plane_state
uses drm_rect_clip_scaled which transforms this to fractional src coords

The core clock computation takes into account both the load due to the
input (ie, planes) and its output (ie, encoders).
However, while the input load needs to consider all the planes, and thus
sum all of their associated loads, the output happens mostly in
parallel.
Therefore, we need to consider only the maximum of all the output loads,
and not the sum like we were doing. This resulted in a clock rate way
too high which could be discarded for being too high by the clock
framework.
Since recent changes, the clock framework will even downright reject it,
leading to a core clock being too low for its current needs.

vc4_drv isn't necessarily under the /soc node in DT as it is a
virtual device, but it is the one that does the allocations.
The DMA addresses are consumed by primarily the HVS or V3D, and
those require VideoCore cache alias address mapping, and so will be
under /soc.
During probe find the a suitable device node for HVS or V3D,
and adopt the DMA configuration of that node.

The PGT (Port Group Table) table maps an index to a bitmap of local ports
to which a packet needs to be replicated. This table is used for layer 2
multicast and flooding.
In the legacy model, software did not interact with PGT table directly.
Instead, it was accessed by firmware in response to registers such as SFTR
and SMID. In the new model, the SFTR register is deprecated and software
has full control over the PGT table using the SMID register.
Use the new PGT APIs to allocate entries for flooding as part of flood
tables initialization. Add mlxsw_sp_fid_flood_tables_fini() to free the
allocated indexes. In addition, use PGT APIs to add/remove ports from PGT
table. The existing code which configures the flood entries via SFTR2 will
be removed later.

The PGT (Port Group Table) table maps an index to a bitmap of local ports
to which a packet needs to be replicated. This table is used for layer 2
multicast and flooding.
The index to PGT table which is called 'mid_index', is a result of
'mid_base' + 'fid_offset'. Using the legacy bridge model, firmware
configures 'mid_base'. However, using the new model, software is
responsible to configure it via SFGC register. The first 15K entries will
be used for flooding and the rest for multicast. The table will look as
follows:
+----------------------------+
| |
| 802.1q, unicast flooding | 4K entries
| |
+----------------------------+
| |
| 802.1q, multicast flooding | 4K entries
| |
+----------------------------+
| |
| 802.1q, broadcast flooding | 4K entries
| |
+----------------------------+
| 802.1d, unicast flooding | 1K entries
+----------------------------+
| 802.1d, multicast flooding | 1K entries
+----------------------------+
| 802.1d, broadcast flooding | 1K entries
+----------------------------+

| |
| Multicast entries | The rest of the table

In Spectrum-1, the index into the MPE table - called switch multicast to
port egress VID (SMPE) - is derived from the PGT entry, whereas in
Spectrum-2 and later ASICs it is derived from the FID.
Therefore, in Spectrum-1, the SMPE index needs to be programmed as part of
the PGT entry via SMID register, while it is reserved for Spectrum-2 and
later ASICs.
Add 'pgt_smpe_index_valid' boolean as part of 'struct mlxsw_sp' and set
it to true for Spectrum-1 and to false for the later ASICs. Add
'smpe_index_valid' as part of 'struct mlxsw_sp_pgt' and set it according

The entire state of the PGT table needs to be maintained in software
because member ports in a PGT entry needs to be reference counted to avoid
releasing entries which are still in use.
Add the following APIs:
1. mlxsw_sp_pgt_{init, fini}() - allocate/free the PGT table.
2. mlxsw_sp_pgt_mid_alloc_range() - allocate a range of MID indexes in PGT.
To be used by FID code during initialization to reserve specific PGT
indexes for flooding entries.
3. mlxsw_sp_pgt_mid_free_range() - free indexes in a given range.
4. mlxsw_sp_pgt_mid_alloc() - allocate one MID index in the PGT at a
non-specific range, just search for free index. To be used by MDB code.
5. mlxsw_sp_pgt_mid_free() - free the given index.

The device includes two main tables to support layer 2 multicast (i.e.,
MDB and flooding). These are the PGT (Port Group Table) table and the MPE
(Multicast Port Egress) table.
- PGT is {MID -> (bitmap of local_port, SPME index)}
- MPE is {(Local port, SMPE index) -> eVID}
In the legacy model, software did not interact with MPE table as it was
completely hidden in firmware. In the new model, software needs to
populate the table itself in order to map from {Local port, SMPE} to an
egress VID. This is done using the SMPE register.
Configure SMPE register when a {Local port, VID} are mapped/unmapped to a
802.1d and 802.1q emulated FIDs. The MPE table is not relevant for rFIDs as
firmware handles their flooding.

Under the legacy bridge model, the field 'bridge_type' is used only
in SFGC register, to determine the type of flood table (FID/FID offset).
Under the unified bridge model, it will be used also in SFMR register.
When a BUM packet needs to be flooded, SFGC is used to provide the
'mid_base' for PGT table. The access to SFGC is by
{packet type, bridge type}. Under the unified bridge model, software is
responsible for configuring 'bridge_type' as part of SFMR.
As preparation for the new required configuration, rename
'enum mlxsw_reg_sfgc_bridge_type' to 'enum mlxsw_reg_bridge_type'. Then
it can be used also in SFMR. In addition, align the names of the values to

As part of transition to unified bridge model, many different firmware
configurations are done.
Some of the configuration that needs to be done for the unified bridge
model is not valid under the legacy model, and would be rejected by the
firmware. At the same time, the driver cannot switch to the unified bridge
model until all of the code has been converted.
To allow breaking the change into patches, and to not break driver
behavior during the transition, add a boolean variable to indicate bridge
model. Then, forbidden configurations will be skipped using the check -
"if (!mlxsw_sp->ubridge)".
The new variable is temporary for several sets, it will be removed when
firmware will be configured to work with unified bridge model.

Merge series from David Jander <david@protonic.nl>:
These patches optimize the spi_sync call for the common case that the
worker thread is idle and the queue is empty. It also opens the
possibility to potentially further optimize the async path also, since
it doesn't need to take into account the direct sync path anymore.
As an example for the performance gain, on an i.MX8MM SoC with a SPI CAN
controller attached (MCP2518FD), the time the interrupt line stays
active (which corresponds roughly with the time it takes to send 3
relatively short consecutive spi_sync messages) is reduced from 98us to
only 72us by this patch.
A note about message ordering:
This patch series should not change the behavior of message ordering when
coming from the same context. This means that if a client driver issues
one or more spi_async() messages immediately followed by a spi_sync()
message in the same context, it can still rely on these messages being
sent out in the order they were fired.

effective_cpu_util() already has a `int cpu' parameter which allows to
retrieve the CPU capacity scale factor (or maximum CPU capacity) inside
this function via an arch_scale_cpu_capacity(cpu).
A lot of code calling effective_cpu_util() (or the shim
sched_cpu_util()) needs the maximum CPU capacity, i.e. it will call
arch_scale_cpu_capacity() already.
But not having to pass it into effective_cpu_util() will make the EAS
wake-up code easier, especially when the maximum CPU capacity reduced
by the thermal pressure is passed through the EAS wake-up functions.
Due to the asymmetric CPU capacity support of arm/arm64 architectures,
arch_scale_cpu_capacity(int cpu) is a per-CPU variable read access via
per_cpu(cpu_scale, cpu) on such a system.
On all other architectures it is a a compile-time constant
(SCHED_CAPACITY_SCALE).

'vlan_bitmap' is a bitmap and is used as such. So allocate it with
devm_bitmap_zalloc() and its explicit bit size (i.e. VLAN_N_VID).
This avoids the need of the VLAN_BITMAP_SIZE macro which:
- needlessly has a 'nic_dev' parameter
- should be "long" (and not byte) aligned, so that the bitmap semantic
is respected
This is in fact not an issue because VLAN_N_VID is 4096 at the time
being, but devm_bitmap_zalloc() is less verbose and easier to understand.

We should respect link partner capabilities and not force flow control
support on every link. Even more, in current state the MAC driver do not
advertises pause support so we should not keep flow control enabled at
all.

If cable is attached after probe sequence, the usbnet framework would
not automatically start processing RX packets except at least one
packet was transmitted.
On systems with any kind of address auto configuration this issue was
not detected, because some packets are send immediately after link state
is changed to "running".
With this patch we will notify usbnet about link status change provided by the
PHYlib.
