This patch adds a private flag to the flexcan driver to switch the
"rx-rtr" setting on and off.
"rx-rtr" on - Receive RTR frames. (default)
The CAN controller can and will receive RTR frames.
On some IP cores the controller cannot receive RTR
frames in the more performant "RX mailbox" mode and
will use "RX FIFO" mode instead.
"rx-rtr" off - Waive ability to receive RTR frames. (not supported on all IP cores)
This mode activates the "RX mailbox mode" for better
performance, on some IP cores RTR frames cannot be
received anymore.
The "RX FIFO" mode uses a FIFO with a depth of 6 CAN frames.
The "RX mailbox" mode uses up to 62 mailboxes.

Most flexcan IP cores support 2 RX modes:
- FIFO
- mailbox
Some IP core versions cannot receive CAN RTR messages via mailboxes.
This patch adds quirks to document this.
This information will be used in a later patch to switch from FIFO to
more performant mailbox mode at the expense of losing the ability to
receive RTR messages. This trade off is beneficial in certain use
cases.

Most flexcan IP cores support 2 RX modes:
- FIFO
- mailbox
The names for these modes were chosen to reflect the name of the
rx-offload mode they are using.
The name of the RX modes should better reflect their difference with
regards the flexcan IP core. So this patch renames the various
occurrences of OFF_FIFO to RX_FIFO and OFF_TIMESTAMP to RX_MAILBOX:
| FLEXCAN_TX_MB_RESERVED_OFF_FIFO -> FLEXCAN_TX_MB_RESERVED_RX_FIFO
| FLEXCAN_TX_MB_RESERVED_OFF_TIMESTAMP -> FLEXCAN_TX_MB_RESERVED_RX_MAILBOX

debug + add rate limiting
A RX overflow usually happens during high system load. Printing
overflow messages to the kernel log, which on embedded systems often
is outputted on the serial console, even increases the system load.
To decrease the system load in these situations, denote the messages
to debug level and wrap them with net_ratelimit().

This patch exchanges the order of open_candev() and

A usual reason why open_candev() fails is missing CAN bit rate

first just to put it to sleep if the bit rate is not configured.

In commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove
already reserved regions") we returned -EBUSY when trying to mark
regions as no-map when they intersect with reserved memory. The goal was
to find bad no-map reserved memory DT nodes that would unmap the kernel
text/data sections.
The problem is the reserved memory check will still trigger if the DT
has a /memreserve/ that completely subsumes the no-map memory carveouts
in the reserved memory node _and_ that region is also not part of the
memory reg property. For example in sc7180.dtsi we have the following
reserved-memory and memory node:
memory@80000000 {
/* We expect the bootloader to fill in the size */
reg = <0 0x80000000 0 0>;
};
smem_mem: memory@80900000 {
reg = <0x0 0x80900000 0x0 0x200000>;
no-map;
};
and the memreserve filled in by the bootloader is
/memreserve/ 0x80800000 0x400000;
while the /memory node is transformed into
memory@80000000 {
/* The bootloader fills in the size, and adds another region */
reg = <0 0x80000000 0 0x00800000>,
<0 0x80c00000 0 0x7f200000>;
};
The smem region is doubly reserved via /memreserve/ and by not being
part of the /memory reg property. This leads to the following warning
printed at boot.
OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB
Otherwise nothing really goes wrong because the smem region is not going
to be mapped by the kernel's direct linear mapping given that it isn't
part of the memory node. Therefore, let's only consider this to be a
problem if we're trying to mark a region as no-map and it is actually
memory that we're intending to keep out of the kernel's direct mapping
but it's already been reserved.

The cells_name field of of_phandle_iterator might be NULL. Use the
phandle name instead. With this change instead of:
OF: /soc/pinctrl@1000000: (null) = 3 found 2
We get:
OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2
Which is a more helpful messages making DT debugging easier.
In this particular example the phandle name looks like duplicate of the
same node name. But note that the first node is the parent node
(it->parent), while the second is the phandle target (it->node). They
happen to be the same in the case that triggered this improvement. See

We currently store large folios as 2^N consecutive entries. While this
consumes rather more memory than necessary, it also turns out to be buggy.
A writeback operation which starts within a tail page of a dirty folio will
not write back the folio as the xarray's dirty bit is only set on the
head index. With multi-index entries, the dirty bit will be found no
matter where in the folio the operation starts.
This does end up simplifying the page cache slightly, although not as
much as I had hoped.
