From 7cf0a66f32eddd5224a288df427f9dfce11f570c Mon Sep 17 00:00:00 2001 From: "Zhu, Lejun" Date: Tue, 3 Jun 2014 13:26:03 +0800 Subject: mfd: intel_soc_pmic: Crystal Cove support This patch provides chip-specific support for Crystal Cove. Crystal Cove is the PMIC in Baytrail-T platform. Also adds Intel SoC PMIC support to the build files.

This can easily be resolved by making CONFIG_MCP_UCB1200 itself a tristate option, since that causes Kconfig to track the dependency correctly.
