You're right. So, I fxied clock name on patch11[1] for CMU_BUSx domains.
- [1] [PATCH 11/19] clk: samsung: exynos5433: Add clocks for CMU_BUS{0|1|2} domains

 	/* DIV_TOP3 */
-	DIV(CLK_DIV_ACLK_IMEM_SSSX, "div_aclk_imem_sssx",
+	DIV(CLK_DIV_ACLK_IMEM_SSSX_266, "div_aclk_imem_sssx_266",
 			"mout_bus_pll_user", DIV_TOP3, 24, 3),
