Subject: [PATCH v5 0/3] Add AM64x ICSSG Ethernet support

Hi All,

This series adds support for ICSSG ethernet on AM64x.
This series is based on the latest next-20240214 linux-next.

AM64x EVM has three ethernet ports. One is dedicated to CPSW and one is
dedicated to ICSSG1. The remaining port is muxed between CPSW and ICSSG1
ICSSG1 ports. The ICSSG1 node is added in the k3-am642-evm.dts. By default
the muxed port is used by CPSW so 2nd ICSSG1 port is disabled in the
k3-am642-evm.dts. But overlay k3-am642-evm-icssg1-dualemac.dtso can be
applied to use muxed port as ICSSG1.

This is the v5 of the series [v1].

Changes from v4 to v5:
*) Added Roger's RB tag in patch 1/3 and 3/3
*) Modified commit message of patch 3/3
*) Dropped ti,syscon-rgmii-delay property from patch 2/3 as it is no
longer needed.
*) Reverted the renaming of mdio-mux nodes back to 'mdio-mux-1' and
'mdio-mux-2' from 'mdio-mux@1' and 'mdio-mux@0' as the later was
throwing DTBS_CHECK warnings.

Changes from v3 to v4:
*) Dropped ethernet3 alias from k3-am642-evm.dts as suggested by Roger.
*) Dropped extra blank lines from k3-am642-evm.dts.
*) Updated commit message of patch 3/3
*) Updated licensing header in k3-am642-evm-icssg1-dualemac.dtso.
*) Fixed up alias for ethernet1 to icssg1_emac1 in
k3-am642-evm-icssg1-dualemac.dtso as suggested by Roger.
*) Renamed 'mdio-mux-1' and 'mdio-mux-2' to 'mdio-mux@1' and 'mdio-mux@0'
respectively as suggested by Roger.

Changes from v2 to v3:
*) No functional changes.
*) Rebased on latest linux-next (next-20240122) after 6.8-rc1.

Changes from v1 to v2:
*) Fixed aliases section in k3-am642-evm.dts
*) Fixed firmware-names in k3-am642-evm.dts
*) Changed icssg1_phy1 to ethernet-phy@f from ethernet-phy@0 as suggested
by Andrew L.
*) Changed makefile to handle overlays using CONFIG_OF_ALL_DTBS as
suggested by Nishant and Andrew Davis.
*) Fixed aliases section in k3-am642-evm-icssg1-dualemac.dtso
*) Fixed pinctrl in k3-am642-evm-icssg1-dualemac.dtso
*) Updated commit message of patch 3/3 of the series to warn about adding
label name to 'mdio-mux-1' node.

Subject: [PATCH v5 3/3] arm64: dts: ti: k3-am642-evm: add overlay for ICSSG1 2nd port

The am642-evm doesn't allow to enable 2 x CPSW3g ports and 2 x ICSSG1 ports
all together, so base k3-am642-evm.dts enables by default 2 x CPSW3g ports
and 1 x ICSSG1 ports, but it is also possible to support 1 x CPSW3g ports
and 2 x ICSSG1 ports configuration.

This patch adds overlay to support 1 x CPSW3g ports and 2 x ICSSG1 ports
configuration:
- Add label name 'mdio_mux_1' for 'mdio-mux-1' node so that the node
'mdio-mux-1' can be disabled in the overlay using the label name.
- disable 2nd CPSW3g port
- update CPSW3g pinmuxes to not use RGMII2
- disable mdio-mux-1 and define mdio-mux-2 to route ICSSG1 MDIO to the
shared DP83869 PHY
- add and enable ICSSG1 RGMII2 pinmuxes
- enable ICSSG1 MII1 port

Subject: [PATCH v5 2/3] arm64: dts: ti: k3-am642-evm: add ICSSG1 Ethernet support

ICSSG1 provides dual Gigabit Ethernet support with proper FW loaded.

The ICSSG1 MII0 (RGMII1) has DP83869 PHY attached to it. The ICSSG1 shares
MII1 (RGMII2) PHY DP83869 with CPSW3g and it's assigned by default to
CPSW3g. The MDIO access to MII1 (RGMII2) PHY DP83869 is controlled by MDIO
bus switch and also assigned to CPSW3g. Therefore the ICSSG1 MII1 (RGMII2)
port is kept disable and ICSSG1 is enabled in single MAC mode by
default.

Subject: [PATCH v5 1/3] arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes

From: Suman Anna <[email protected]>

The ICSSG IP on AM64x SoCs have two Industrial Ethernet Peripherals (IEPs)
to manage/generate Industrial Ethernet functions such as time stamping.
Each IEP sub-module is sourced from an internal clock mux that can be
derived from either of the IP instance's ICSSG_IEP_GCLK or from another
internal ICSSG CORE_CLK mux. Add both the IEP nodes for both the ICSSG
instances. The IEP clock is currently configured to be derived
indirectly from the ICSSG_ICLK running at 250 MHz.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/3] arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes
commit: d4e8c8ad5d14ad51ed8813442d81c43019fd669d
[2/3] arm64: dts: ti: k3-am642-evm: add ICSSG1 Ethernet support
commit: efb32a10a10d92f4bc3380106bd3b003ea790aa3
[3/3] arm64: dts: ti: k3-am642-evm: add overlay for ICSSG1 2nd port
commit: ae0aba1218a0c67f144706c48502f534b2756491

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
