ARM: dts: sbc-t3517: add support for sbc-t3517
Add support for CM-T3517 CoM and SBC-T3517 board. reused common support for sbc-t3x boards (omap3-cm-t3x.dtsi, omap3-sb-t35.dtsi): * SB-T35 baseboard eth * MMC1, UART3 * HS USB Port 1/2 * I2C1/3 * Heartbit led Added basic support for: * MMC1 wp/cd signals * CM-T3517 Usb Hub * WL12xx WiFi chip * Davinci EMAC * AM35X OTG Signed-off-by: Dmitry Lifshitz <lifshitz@compulab.co.il> Signed-off-by: Tony Lindgren <tony@atomide.com>
