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 659/660] arm64: dts: uDPU: SFP cages support 3W modules
|
|
|
|
The SFP cages are designed to support up to 3W modules, such as G.hn,
|
|
G.fast and MoCA modules. Although there is no way for such modules to
|
|
declare to software that they consume 3W, we document in DT that this
|
|
is the designed power level for these cages.
