From b3b9d7ca324429319df1d1f246643d2ae928beb6 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 5 Jun 2015 14:39:34 -0600 Subject: [PATCH] dm: tegra: cros_ec: Enable Chrome OS EC on Nyan-big 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.
