phyCORE-AM335x is a SoM (System on Module) containing
a AM335x SOC. The module can be connected to different
carrier boards.
Some hardware parts are configurable on the phyCORE-AM335x.
So they are disabled on default in this som dtsi file.
They will be enabled in the board dts files, when populated.
* RAM up to 1GiB
* PMIC
* NAND flash up to 1GiB
* Eth PHY on SOM: 1x RMII
* SPI NOR flash 8MiB (optional)
* i2c RTC (optional)
* i2c EEPROM 4kiB (optional)

phyBOARD-WEGA-AM335x represents a direct soldered
combination of a phyCORE-AM335x SoM and carrier board.
Different kind of SoM options can be connected to
the wega carrier board. So we created a separate
wega dtsi file. The final dts contains the actual
SoM on the carrier board.
WEGA carrier board features:
* ETH phy on carrier board: 1x MII
* 1x CAN
* 2x UART
* USB0 (device)
* USB1 (host)
* mSD slot

Applying both into omap-for-v4.3/dt thanks.

One minor thing here...wildcards in compatible strings aren't permitted.
However, family compatibles like "ti,am33xx" that came in before this
was enforced are grandfathered. Ideally, the newly introced board/som
specific strings should not propagate that wildcard. i.e. something
like "phytec,am3352-phycore-som" or whatever is the base family part
on these SOMs.

I'm not sure this is wild card.
