ARM: imx: select CPU_FREQ_TABLE when needed
The i.MX cpufreq implementation uses the CPU_FREQ_TABLE helpers, so it needs to select that code to be built. This problem has apparently existed since the i.MX cpufreq code was first merged in v2.6.37. Building IMX without CPU_FREQ_TABLE results in: arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_exit': arch/arm/plat-mxc/cpufreq.c:173: undefined reference to `cpufreq_frequency_table_put_attr' arch/arm/plat-mxc/built-in.o: In function `mxc_set_target': arch/arm/plat-mxc/cpufreq.c:84: undefined reference to `cpufreq_frequency_table_target' arch/arm/plat-mxc/built-in.o: In function `mxc_verify_speed': arch/arm/plat-mxc/cpufreq.c:65: undefined reference to `cpufreq_frequency_table_verify' arch/arm/plat-mxc/built-in.o: In function `mxc_cpufreq_init': arch/arm/plat-mxc/cpufreq.c:154: undefined reference to `cpufreq_frequency_table_cpuinfo' arch/arm/plat-mxc/cpufreq.c:162: undefined reference to `cpufreq_frequency_table_get_attr' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shawn Guo <shawn.guo@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Yong Shen <yong.shen@linaro.org> Cc: stable@vger.kernel.org
