mdio_bus: Add generic mdio_find_bus() Browse files It appears most ethernet drivers follow one of two main strategies for mdio bus/phy management. A monolithic model where the net driver itself creates, probes and uses the phy, and one where an external mdio/phy driver instantiates the ...
针对你提出的“can't register mdio bus”问题,以下是一些可能的解决步骤和考虑因素,帮助你定位和解决问题: 检查MDIO总线驱动是否正确加载: 确保MDIO总线驱动已经正确加载到内核中。你可以通过以下命令来检查MDIO驱动模块是否已经加载: bash lsmod | grep mdio 如果驱动没有加载,你可以尝试手动加载它,使用如下命令:...

…ror handling The current code in __mdiobus_register() doesn't properly handle failures returned by the devm_gpiod_get_optional() call: it returns immediately, without unregistering the device that was added by the call to device_register() earlier in the function. This leaves a stale devi...

MDIO Bus System The MDIO interface for 1 Gb/s operation (and slower speeds) is defined in IEEE 802.3-2012, clause 22.This Figureillustrates an example of MDIO bus system. This two-wire interface consists of a clock (MDC) and a shared serial data line (MDIO). The maximum permitted freque...
Part Number: TDA4VM Hi, We have our external phys connected the mdio bus. Our external switch is connected to the internal CPSW02 with mac-mac connection. The
It is easy to solve this problem when we know the reason, but what I don't understand is why of_mdiobus_register() takes it is fine when PHY id read failed and go ahead to register the enet device, if this is not a problem, why the attached/detached of enet cable ca...

The invention discloses an MDIO bus slave unit and a method for improving anti-jamming capability. The method comprises the steps of running a local high-speed clock on the MDIO bus slave unit, capturing the starting moments of the rising edge and the falling edge of a received MDC main ...
