From 6fb9ac15ebac4bcc4864be7958bf9b2b2b7420de Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 13 Feb 2015 12:20:47 -0700 Subject: [PATCH] dm: cros_ec: Convert to Kconfig Since both I2C and SPI are converted to Kconfig, we can convert cros_ec to Kconfig for these buses. LPC will need to wait until driver mode PCI is available.
