Hi Tero/Nishanth,
This series adds USB2.0 support for the J7200 EVM.
Series is based on top of:
Faiz's MMC/SD support series
https://lore.kernel.org/lkml/[email protected]/
Lokesh's initial support series
https://patchwork.kernel.org/cover/11740039/
Vignesh's I2C support series
https://lore.kernel.org/patchwork/cover/1282152/
Vignesh's Hyperflash series
https://lore.kernel.org/patchwork/cover/1285326/
cheers,
-roger

Each SERDES lane mux can select upto 4 different IPs.
There are 4 lanes in each J7200 SERDES. Define all
the possible functions in this file.
