Subject: [PATCH 06/12] ARM: dts: Exynos5800: fix CPU OPP
Date: Wed, 2 Dec 2015 22:19:21 +0100 [thread overview]
Message-ID: <1449091167-20758-7-git-send-email-ben@smart-cactus.org> (raw)
In-Reply-To: <1449091167-20758-1-git-send-email-ben@smart-cactus.org>
From: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
Fix CPU operating points for Exynos5800 (it uses different
voltages than Exynos5420 and supports additional frequencies).
However don't use 2000MHz & 1900MHz OPPs (for A15 cores) and
1400MHz OPP (for A7 cores) until there is a separate DTS for
ODROID-XU3 Lite board (which doesn't support these higher
OPPs).
Based on Hardkernel's kernel for ODROID-XU3 board.
