Subject: tegra: dts: Add cros-ec SPI settings
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c415dda8df1134ba60ff031110649ca4e2735174;p=u-boot.git

tegra: dts: Add cros-ec SPI settings

At present the interrupt does not work and the SPI bus runs much less
quickly than it should. Add settings to fix this.
