The BCM2711 has a new way of selecting the pull-up/pull-down setting

GP_PUDCLKn0, are no longer connected. A new set of registers,

xhci: Use more event ring segment table entries
Users have reported log spam created by "Event Ring Full" xHC event
TRBs. These are caused by interrupt latency in conjunction with a very
busy set of devices on the bus. The errors are benign, but throughput
will suffer as the xHC will pause processing of transfers until the
event ring is drained by the kernel. Expand the number of event TRB slots
available by increasing the number of event ring segments in the ERST.
Controllers have a hardware-defined limit as to the number of ERST
entries they can process, so make the actual number in use
min(ERST_MAX_SEGS, hw_max).

net: bcmgenet: Workaround #2 for Pi4 Ethernet fail
Some combinations of Pi 4Bs and Ethernet switches don't reliably get a
DCHP-assigned IP address, leaving the unit with a self=assigned 169.254
address. In the failure case, the Pi is left able to receive packets
but not send them, suggesting that the MAC<->PHY link is getting into
a bad state.
It has been found empirically that skipping a reset step by the genet
driver prevents the failures. No downsides have been discovered yet,
and unlike the forced renegotiation it doesn't increase the time to
get an IP address, so the workaround is enabled by default; add
genet.skip_umac_reset=n
to the command line to disable it.

bcm2835-codec is a little different from other decoder implementations

independent of the stream and DPB etc.
