Kernel 5.4 receives a reduced set, just to make the SFP cage work.
While we are at it, move the patches accepted upstream to the 0xx series.

+
+The eth2 controller on Turris Omnia is connected to SerDes. For SFP to
+be able to switch between 1G and 2.5G modes the comphy link has to be
+defined.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Turris Omnia has an SFP cage that, together with WAN PHY, is connected
+to eth2 SerDes via a SerDes multiplexor. When a SFP module is present,
+the multiplexor switches the SerDes signal from PHY to SFP.
+
+Describe the SFP cage, but leave it disabled. Until phylink has support
+for such configuration, we are leaving it to U-Boot to enable SFP and
+disable WAN PHY at boot time depending on whether a SFP module is
+present.

+
+Use property name `phy-handle` instead of the deprecated `phy` to
+connect eth2 to the PHY.
+Rename the node from "phy@1" to "ethernet-phy@1", since "phy@1" is
+incorrect according to device-tree bindings documentation.
+Also remove the "ethernet-phy-id0141.0DD1" compatible string, it is not
+needed. Kernel can read the PHY identifier itself.

Hardware buffer management has never worked on the Turris Omnia, as the
required MBus window hadn't been reserved. Fix thusly.
