This patchset for the lantiq_gswip driver is a collection of minor fixes
and coding improvements by Martin Blumenstingl without any real changes
in the actual functionality.
=== Changelog ===
From v4:
- merge dt-bindings patches to satisfy 'make dt_bindings_check' and add
some improvements suggested by Rob Herring
From v3:
- convert lantiq,gswip bindings to YAML schema
- Add Hauke's acked-by as mentioned in the cover letter in v1
From v2:
- removed unused variable max_ports in gswip_add_single_port_br()
From v1:
- signal that we only update example code in dt-bindings
- don't use the word 'fix' if not appropriate
- new patch: add terminating '\n' where missing
- renamed MAC_BRIDGE macros to make it obvious which register field is
used
- new patch: remove dead code from gswip_add_single_port_br()
- updated error message if FID not found in gswip_port_fdb()
Martin Blumenstingl (8):
net: dsa: lantiq_gswip: Only allow phy-mode = "internal" on the CPU
port
net: dsa: lantiq_gswip: Use dev_err_probe where appropriate
net: dsa: lantiq_gswip: Don't manually call gswip_port_enable()
net: dsa: lantiq_gswip: Use dsa_is_cpu_port() in

table

2.39.2
From: Martin Blumenstingl <[email protected]>
Add the CPU port to gswip_xrx200_phylink_get_caps() and
gswip_xrx300_phylink_get_caps(). It connects through a SoC-internal bus,
so the only allowed phy-mode is PHY_INTERFACE_MODE_INTERNAL.

We don't need to manually call gswip_port_enable() from within
gswip_setup() for the CPU port. DSA does this automatically for us.

2.39.2
Before commit 74be4babe72f ("net: dsa: do not enable or disable non user
ports"), gswip_port_enable/disable() were also executed for the cpu port
in gswip_setup() which disabled the cpu port during initialization.
Let's restore this by removing the dsa_is_user_port checks. Also, let's
clean up the gswip_port_enable() function so that we only have to check
for the cpu port once. The operation reordering done here is safe.

Convert the lantiq,gswip bindings to YAML format.
Also add this new file to the MAINTAINERS file.
Furthermore, the CPU port has to specify a phy-mode and either a phy or
a fixed-link. Since GSWIP is connected using a SoC internal protocol
there's no PHY involved. Add phy-mode = "internal" and a fixed-link to
the example code to describe the communication between the PMAC
(Ethernet controller) and GSWIP switch.

dev_err_probe() can be used to simplify the existing code. Also it means
we get rid of the following warning which is seen whenever the PMAC
(Ethernet controller which connects to GSWIP's CPU port) has not been
probed yet:

Only bits [5:0] in mac_bridge.key[3] are reserved for the FID.
Also, for dynamic (learned) entries, bits [7:4] in mac_bridge.val[0]
represents the port.
Introduce new macros GSWIP_TABLE_MAC_BRIDGE_KEY3_FID and
GSWIP_TABLE_MAC_BRIDGE_VAL0_PORT macro and use it throughout the driver.
Also rename and update GSWIP_TABLE_MAC_BRIDGE_VAL1_STATIC to use the
BIT() macro. This makes the driver code easier to understand.
