Subject: [PATCH 1/2] clk: samsung: Don't build ARMv8 clock drivers on ARMv7
Date: Mon, 16 Nov 2015 10:36:14 +0900
Message-id: <1447637775-9887-2-git-send-email-k.kozlowski@samsung.com>
In-reply-to: <1447637775-9887-1-git-send-email-k.kozlowski@samsung.com>

Currently the Exynos5433 (ARMv8 SoC) clock driver depends on ARCH_EXYNOS
so it is built also on ARMv7. This does not bring any kind of benefit.
There won't be a single kernel image for ARMv7 and ARMv8 SoCs (like
multi_v7 for ARMv7).

Instead build clock drivers only for respective SoC's architecture.
