ARM: dts: Add basic support for omap3 LDP zoom1 labrador
Basic things like serial, Ethernet, MMC, NAND, DSS, touchscreen and GPIO keys work. For twl4030-keypad we're still missing the binding, but support for that should be trivial to add once the driver has been updated. MUSB I'm pretty sure I got got to enumerate once, but I suspect the battery charging somehow disrupts it and it's not enumerating in general for some reason. Patches are welcome to improve things if people are still using this board. For reference, here's some more info on this old board: http://www.openomap.org/wiki/tiki-index.php?page=HardwareInfo Cc: devicetree@vger.kernel.org Cc: "Benoît Cousson" <bcousson@baylibre.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
