[DistroKit] [PATCH 0/2] v7a: fix beaglebone networking

[Ahmad Fatoum]

Upstream device tree changed TI CPSW (network controller) node our kernel
and barebox to a new one with a compatible we don't match against.

Fix this up for kernel and barebox and while at it import one more
beaglebone fix from barebox master.

[DistroKit] [PATCH 1/2] v7a: kernel: enable new TI CPSW switchdev driver

[Ahmad Fatoum]

The kernel now has two CPSW drivers and the device tree has two device
tree nodes, where one or the other may be enabled. The upstream device
tree was switched to new switchdev-based CPSW in v5.15-rc1.

Update our kernelconfig to enable the appropriate driver to get
networking working again on the Beaglebone Black.

[DistroKit] [PATCH 2/2] v7a: barebox: cherry-pick CPSW/Linux reboot fixes from master

[Ahmad Fatoum]

The upstream device tree change addressed by the previous commit
also made it into barebox and broke Beaglebone networking there.
This is fixed in master, so import the patch.

It was also reported that bumping bumping up core clock frequency for
faster boot times broke reboot from within Linux.

This might be brown out resulting from Linux scaling down the
voltage and Linux system reset not affecting the PMIC. Until that's
resolved, barebox master reverts the overclocking, so import that patch
as well. Both patches are scheduled to appear in v2022.01.0.

Fixes: 949c5ef2 ("v7a: barebox: version bump v2021.08.0 → v2021.11.0") # CPSW
Fixes: afdae878 ("v7a: barebox: version bump v2021.05.0 → v2021.07.0") # reset

+Subject: [PATCH 1/2] net: cpsw: add support for new binding in Linux v5.15-rc1
+ DTs
+
+As is customary, upstream OMAP DTs have yet again added a new binding
+breaking compatibility with a barebox driver. This time, the old Ethernet
+node was disabled in favor of a new node that is matched by the new Linux
+cpsw driver introduced with Linux commit ed3525eda4c4 ("net: ethernet:
+ti: introduce cpsw switchdev based driver part 1 - dual-emac").
+
+Add support for the new binding to restore working Beaglebone Black
+networking. These changes have been tested against both the old and new
+bindings.

+Commit 130c7d6715e9 ("ARM: beaglebone: init MPU speed to 800Mhz") causes
+warm reboot from within Linux v5.14.0 to no longer succeed.
+barebox MLO is entered, but hangs. Reset from within barebox is
+unaffected.
+This can be reproduced using DistroKit 949c5ef2b9a6 ("v7a: barebox:
+version bump v2021.08.0 → v2021.11.0") on a Beaglebone Black.
+Until that's figured out, revert the commit; functional reboot is more
