------------------ From: Shawn Guo <shawn....@linaro.org> commit 28a9f3b078c545064dcf4b46d2c6917554d1642e upstream. When building a kernel image with only CONFIG_CPU_IDLE but no CONFIG_PM, we will get the following link error. LD init/built-in.o arch/arm/mach-imx/built-in.o: In function `imx6q_enter_wait': platform-spi_imx.c:(.text+0x25c0): undefined reference to `imx6q_set_lpm' platform-spi_imx.c:(.text+0x25d4): undefined reference to `imx6q_set_lpm' arch/arm/mach-imx/built-in.o: In function `imx6q_cpuidle_init': platform-spi_imx.c:(.init.text+0x75d4): undefined reference to `imx6q_set_chicken_bit' make[1]: *** [vmlinux] Error 1 Since pm-imx6q.c has been a collection of library functions that access CCM low-power registers used by not only suspend but also cpuidle and other drivers, let's build pm-imx6q.c independently of CONFIG_PM to fix above error.
