It seems that we have a merge issue between:

patch "dt-bindings: rcc: Add optional external ethernet RX clock properties"
https://lore.kernel.org/r/20220410220514.21779-1-marex@denx.de

and this one (dt-bindings: clock: stm32mp1: describes clocks if
"st,stm32mp1-rcc-secure)

On linux-next following part remains and creates issue above:

clocks:
description:
Specifies the external RX clock for ethernet MAC.
maxItems: 1

clock-names:
const: ETH_RX_CLK/ETH_REF_CLK

I don't know why this part is remaining. In my tree, I took care to take
Marek patch first to avoid this kind of issue.

Btw, how to fix that ?

Note, that as soon as we will fix this point I'll send a fix to avoid
issue in example build.

cheers
Alex
