Looks good to me. Acked-by: Chanwoo Choi <cw00.choi@samsung.com> Additionally, IMO, samsung_clk_add_lookup() might have to check whether 'ctx->clk_data.hws[id]' is NULL or not before adding lookup_id in order to prevent the overwriting. -- Best Regards, Chanwoo Choi Samsung Electronics -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

CLK_ARM_CLK ("armclk") clock is provided by cpu-clk subdriver, which is instantiated after creating all divider clocks from exynos4_div_clks array. There is no point assigning this id to "div_core2" clock and later overwrite with proper "armcpu" clock by cpu-clk subdriver.
