The code here is:
if (data->soc == SOC_ARCH_EXYNOS5260)
	emul_con = EXYNOS5260_EMUL_CON;
if (data->soc == SOC_ARCH_EXYNOS5433)
	emul_con = EXYNOS5433_TMU_EMUL_CON;
else if (data->soc == SOC_ARCH_EXYNOS7)
	emul_con = EXYNOS7_TMU_REG_EMUL_CON;
else
	emul_con = EXYNOS_EMUL_CON;

So if data->soc is SOC_ARCH_EXYNOS5260 , then emul_con becomes
EXYNOS5260_EMUL_CON. But again for the else part it will become
EXYNOS_EMUL_CON.
