If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai commit fdc0074c5fc8c7adb8186cbb123fe2082d9bd05f upstream. As the sunxi usb clocks all contain a reset controller, it is not possible to build the sunxi clock driver without RESET_CONTROLLER enabled. Doing so results in an undefined symbol error: drivers/built-in.o: In function `sunxi_gates_clk_setup': linux/drivers/clk/sunxi/clk-sunxi.c:1071: undefined reference to `reset_controller_register' This is possible if building a minimal kernel without PHY_SUN4I_USB. The dependency issue is made visible at compile time instead of link time by the new A80 mmc clocks, which also use a reset control itself. This patch makes ARCH_SUNXI select ARCH_HAS_RESET_CONTROLLER and RESET_CONTROLLER.
