Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

* Freescale Fast Ethernet Controller (FEC)
|
|
|
|
Required properties:
|
|
- compatible : Should be "fsl,<soc>-fec"
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts : Should contain fec interrupt
|
|
- phy-mode : See ethernet.txt file in the same directory
|
|
|
|
Optional properties:
|
|
- phy-reset-gpios : Should specify the gpio for phy reset
|
|
- phy-reset-duration : Reset duration in milliseconds. Should present
|
|
only if property "phy-reset-gpios" is available. Missing the property
|
|
will have the duration be 1 millisecond. Numbers greater than 1000 are
|
|
invalid and 1 millisecond will be used instead.
|
|
- phy-reset-active-high : If present then the reset sequence using the GPIO
|
|
specified in the "phy-reset-gpios" property is reversed (H=reset state,
|
|
L=operation state).
|
|
- phy-reset-post-delay : Post reset delay in milliseconds. If present then
|
|
a delay of phy-reset-post-delay milliseconds will be observed after the
|
|
phy-reset-gpios has been toggled. Can be omitted thus no delay is
|
|
observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.
|
|
- phy-supply : regulator that powers the Ethernet PHY.
|
|
- phy-handle : phandle to the PHY device connected to this device.
|
|
- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
|
|
Use instead of phy-handle.
|
|
- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
|
|
hw multi queues. Should specify the tx queue number, otherwise set tx queue
|
|
number to 1.
|
|
- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
|
|
hw multi queues. Should specify the rx queue number, otherwise set rx queue
|
|
number to 1.
|
|
- fsl,magic-packet : If present, indicates that the hardware supports waking
|
|
up via magic packet.
|
|
- fsl,err006687-workaround-present: If present indicates that the system has
|
|
the hardware workaround for ERR006687 applied and does not need a software
|
|
workaround.
|
|
|
|
Optional subnodes:
|
|
- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
|
|
according to phy.txt in the same directory
|
|
|
|
Example:
|
|
|
|
ethernet@83fec000 {
|
|
compatible = "fsl,imx51-fec", "fsl,imx27-fec";
|
|
reg = <0x83fec000 0x4000>;
|
|
interrupts = <87>;
|
|
phy-mode = "mii";
|
|
phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
|
|
local-mac-address = [00 04 9F 01 1B B9];
|
|
phy-supply = <®_fec_supply>;
|
|
};
|
|
|
|
Example with phy specified:
|
|
|
|
ethernet@83fec000 {
|
|
compatible = "fsl,imx51-fec", "fsl,imx27-fec";
|
|
reg = <0x83fec000 0x4000>;
|
|
interrupts = <87>;
|
|
phy-mode = "mii";
|
|
phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
|
|
local-mac-address = [00 04 9F 01 1B B9];
|
|
phy-supply = <®_fec_supply>;
|
|
phy-handle = <ðphy>;
|
|
mdio {
|
|
ethphy: ethernet-phy@6 {
|
|
compatible = "ethernet-phy-ieee802.3-c22";
|
|
reg = <6>;
|
|
max-speed = <100>;
|
|
};
|
|
};
|
|
};
