description: | |
If the QCA8K switch is connect to an SoC's external mdio-bus, each subnode | |
describing a port needs to have a valid phandle referencing the internal PHY | |
it is connected to. This is because there is no N:N mapping of port and PHY | |
ID. To declare the internal mdio-bus configuration, declare an MDIO node in | |
the switch node and declare the phandle for the port, referencing the internal | |
PHY it is connected to. In this config, an internal mdio-bus is registered and | |
the MDIO master is used for communication. Mixed external and internal | |
mdio-bus configurations are not supported by the hardware. | |

qca,sgmii-rxclk-falling-edge: | |
$ref: /schemas/types.yaml#/definitions/flag | |
description: | |
Set the receive clock phase to falling edge. Mostly commonly used on | |
the QCA8327 with CPU port 0 set to SGMII. | |
qca,sgmii-txclk-falling-edge: | |
$ref: /schemas/types.yaml#/definitions/flag | |
description: | |
Set the transmit clock phase to falling edge. | |
qca,sgmii-enable-pll: | |
$ref: /schemas/types.yaml#/definitions/flag | |
description: | |
For SGMII CPU port, explicitly enable PLL, TX and RX chain along with | |
Signal Detection. On the QCA8327 this should not be enabled, otherwise | |
the SGMII port will not initialize. When used on the QCA8337, revision 3 | |
or greater, a warning will be displayed. When the CPU port is set to | |
SGMII on the QCA8337, it is advised to set this unless a communication | |
issue is observed. | |
qca,ignore-power-on-sel: | |
$ref: /schemas/types.yaml#/definitions/flag | |
description: | |
Ignore power-on pin strapping to configure LED open-drain or EEPROM | |
presence. This is needed for devices with incorrect configuration or when | |
the OEM has decided not to use pin strapping and falls back to SW regs. | |
qca,led-open-drain: | |
$ref: /schemas/types.yaml#/definitions/flag | |
description: | |
Set LEDs to open-drain mode. This requires the qca,ignore-power-on-sel to | |
be set, otherwise the driver will fail at probe. This is required if the | |
OEM does not use pin strapping to set this mode and prefers to set it | |
using SW regs. The pin strappings related to LED open-drain mode are | |
B68 on the QCA832x and B49 on the QCA833x. | |
