Subject: [PATCH v1 18/50] ARM: dts: exynos: add bus_isp with OPP table
Date:   Mon, 15 Jul 2019 14:43:45 +0200

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add bus_isp which controls ACLK400_ISP clock. The OPPs are aligned to
parent clock and PLL rate so that the PLL would not need to be
reprogrammed.
