From aa14b42d53b03b9b9d7e19e4cb5f9e59f881c4dc Mon Sep 17 00:00:00 2001 From: Akshay Saraswat Date: Thu, 13 Nov 2014 22:38:15 +0530 Subject: Exynos5800: Introduce new proid for Exynos5800 This patch intends to add a new proid for Exynos5800 which is a variant of Exynos5420. Product id for Exynos5800 is 0x5422. Both Exynos5420 and Exynos5800 are pin to pin compitable. This gives us an advantage of reusing Exynos5420 clock, pinmux, memory and other settings.
