Update the uDPU kernel support, fixing a number of issues: * make ethernet work again by adding comphy definitions * slow the I2C bus to give it more chance of actually working * the SFP cages are designed to support up to 3W modules, which would be prevented from initialising without this patch.

Subject: [PATCH 657/660] arm64: dts: uDPU: fix comphy definitions
|
|
|
|
The uDPU uses both ethernet controllers, which ties up COMPHY 0 for
|
|
eth1 and COMPHY 1 for eth0, with no USB3 comphy. The addition of
|
|
COMPHY support made the kernel override the setup by the boot loader
|
|
breaking this platform. Delete the USB3 COMPHY definition at platform
|
|
level, and add phy specifications for the ethernet channels.
|
