arm64: dts: ti: iot2050: Factor out DP related bits

There is a variant coming which does not support the Display Port. Move
all related bits into a separate dtsi so that only those variants
supporting the interface can include it.

Along that, remove a redundant clock setting from
k3-am65-iot2050-common-pg1.dtsi.

arm64: dts: ti: iot2050: Factor out arduino connector bits

A new variant is to be added which will not have a arduino connector
like the existing ones. Factor out all bits that are specific to this
connector.

The split is not perfect because wkup_gpio0 is defined based on what is
common to all variants having the connector, thus containing also
connector-unrelated information. But this is still cleaner than

arm64: dts: ti: k3-am62-main: disable usb lpm

AM62 USB works with some devices, while failing to operate with others.

arm64: dts: ti: k3-am62-wakeup: Configure ti-sysc for wkup_uart0

The devices in the wkup domain are capable of waking up the system from
suspend. We can configure the wkup domain devices in a generic way using
the ti-sysc interconnect target module driver like we have done with the
earlier TI SoCs.

As ti-sysc manages the SYSCONFIG related registers independent of the
child hardware device, the wake-up configuration is also set even if
wkup_uart0 is reserved by sysfw.

The wkup_uart0 device has interconnect target module register mapping like
dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP
block in the target module. The power domain and clock affects the whole
interconnect target module.

Note we change the functional clock name to follow the ti-sysc binding
and use "fck" instead of "fclk".

Also note that we need to disable the target module reset as noted by
Markus. Otherwise the sysfw using wkup_uart0 can get confused on some
devices leading to boot time issues such as mbox timeouts.

arm64: dts: ti: k3-am625-beagleplay: Use the builtin mdio bus

The beagleplay dts was using a bit-bang gpio mdio bus as a work-around
for errata i2329. However since commit d04807b80691 ("net: ethernet: ti:
davinci_mdio: Add workaround for errata i2329") the mdio driver itself
already takes care of this errata for effected silicon, which landed
well before the beagleplay dts. So i suspect the reason for the
workaround in upstream was simply due to copying the vendor dts.

Switch the dts to the ti,cpsw-mdio instead so it described the actual

bcachefs: opts->compression can now also be applied in the background

The "apply this compression method in the background" paths now use the
compression option if background_compression is not set; this means that
setting or changing the compression option will cause existing data to
be compressed accordingly in the background.

bcachefs: Prep work for variable size btree node buffers

bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.

And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.

Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

bcachefs: grab s_umount only if snapshotting

When I was testing mongodb over bcachefs with compression,
there is a lockdep warning when snapshotting mongodb data volume.

$ cat test.sh
prog=bcachefs

$prog subvolume create /mnt/data
$prog subvolume create /mnt/data/snapshots

while true;do
    $prog subvolume snapshot /mnt/data /mnt/data/snapshots/$(date +%s)
    sleep 1s
done

$ cat /etc/mongodb.conf

======================================================

In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.

Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().
