Subject: [PATCH v1 08/50] clk: samsung: change aclk266_isp clocks

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

The ACLK266_ISP has different topology in Exynos5420 and 5422/5800.  In
Exynos5420 this clock does not have dedicated MUX which chooses PLL instead
it takes the clock from 2-level mux from ACLK266.  In Exynos5422 there is a
dedicated clock tree and the PLL can be chosen.  The patch adds needed
MUXes in the exynos5800_mux_cloks, updates exynos5x_mux_clks and
exynos5420_mux_clks properly. It also adds IDs to mange these clocks from
DT.
