From 98167430317a6275e582def8cb4aee76799789af Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 28 May 2015 21:25:33 +0800 Subject: [PATCH] ARM: sunxi: Share sun6i PSCI backend with sun8i sun8i can share the PSCI backend with sun6i. Only difference is sun8i does not have CPU power clamp controls.
