The phyCORE-AM335x development kit is a combination of the phyCORE-AM335x SoM and a PCM-953 carrier board. The features of the PCM-953 are: * ETH phy on carrier board: 1x RGMII * 1x CAN * Up to 4x UART * USB0 (otg) * USB1 (host) * SD slot * User gpio-keys * User LEDs Signed-off-by: Teresa Remmet <t.remmet@phytec.de> Reviewed-by: Wadim Egorov <w.egorov@phytec.de> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
