[PATCH v2 0/2] Add ICSSG MDIO nodes on AM65x & J721E SoCs

[Suman Anna]

Hi Nishanth,

he following series is a resend of the ICSSG DT nodes [1] for the 5.14
merge window. Patches are just rebased on top of 5.13-rc1 + your latest
ti-k3-dts-next branch HEAD commit 69db725cdb2b ("arm64: dts: ti:
k3-am654x/j721e/j7200-common-proc-board: Fix MCU_RGMII1_TXC direction")
+ Aswath's AM65x MMCSD1 UHS-I patch [2]. There are no code changes w.r.t
v1, I have picked up Reviewed-by tags from Jan and Grygorii.

regards
Suman

[PATCH v2 1/2] arm64: dts: ti: k3-am65-main: Add ICSSG MDIO nodes

[Suman Anna]

From: Roger Quadros <rogerq@ti.com>

The ICSSGs on K3 AM65x SoCs contain an MDIO controller that can
be used to control external PHYs associated with the Industrial
Ethernet peripherals within each ICSSG instance. The MDIO module
used within the ICSSG is similar to the MDIO Controller used
in TI Davinci SoCs. A bus frequency of 1 MHz is chosen for the
MDIO operations.

The nodes are added and enabled in the common k3-am65-main.dtsi
file by default, and disabled in the existing AM65 board dts
files. These nodes need pinctrl lines, and so should be enabled
only on boards where they are actually wired and pinned out for
ICSSG Ethernet. Any new board dts file should disable these if
they are not sure.

[PATCH v2 2/2] arm64: dts: ti: k3-j721e-main: Add ICSSG MDIO nodes

The ICSSGs on K3 J721E SoCs contain an MDIO controller that can
be used to control external PHYs associated with the Industrial
Ethernet peripherals within each ICSSG instance. The MDIO module
used within the ICSSG is similar to the MDIO Controller used
in TI Davinci SoCs. A bus frequency of 1 MHz is chosen for the
MDIO operations.

The nodes are added and enabled in the common k3-j721e-main.dtsi
file by default, and disabled in the existing J721E board dts
file. These nodes need pinctrl lines, and so should be enabled
only on boards where they are actually wired and pinned out for
ICSSG Ethernet. Any new board dts file should disable these if
they are not sure.

Hi Suman Anna,

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

[1/2] arm64: dts: ti: k3-am65-main: Add ICSSG MDIO nodes
      commit: d49a769dcddd4224bd631792a4d2e5bbb160aa20
[2/2] arm64: dts: ti: k3-j721e-main: Add ICSSG MDIO nodes
      commit: 7ce11d4704c080ab890831b8255fbba4d2b0c5ec


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.
