* dm: tegra: cros_ec: Enable Chrome OS EC on Nyan-bigSimon Glass2015-06-09-0/+3
| | | | | | | | | | | | | Enable the EC and keyboard, using the SPI bus. The EC driver requires a particular format and a deactivation delay. Also U-Boot does not support interrupts. For now, adjust the device tree to comply. At some point we should tidy this up to support interrupts and make tegra and exynos use the same setup.

* tegra: nyan-big: Add LCD PMIC init and board IDSimon Glass2015-05-13-0/+4
| | | | | | | | Add required setup for the LCD display, and a function to provide the board ID. This requires GPIOs to be available prior to relocation. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* dm: usb: tegra: Add vbus GPIOs for nyanSimon Glass2015-04-18-0/+2
| | | | | | | | These are needed to enable the USB bus (although not sufficient since it still does not work). Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Marek Vasut <marex@denx.de>
* ARM: tegra: Add support for nyan-big boardAllen Martin2014-12-11-0/+365
Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but it has a different panel, the sdcard cd and wp sense are flipped, and it has a different revision of the AS3722 PMIC. This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA Tegra K1, 2GB). The display is not currently supported, so it should boot on other nyan-based Chromebooks also, but only the device tree for nyan-big is provided here. The device tree file is from Linux but with features removed which are unlikely to be supported in U-Boot soon (regulators, pinmux). Also the addresses are updated to 32-bit.
