There are more and more requirements of building SoC specific drivers as modules, add support for building SCU clock driver as module to meet the requirement.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com> --- Changes since V1: - add ARCH_MXC to build dependency to avoid build fail on x86 arch; - move clk-lpcg-scu.c change in to this patch. --- drivers/clk/imx/Kconfig | 4 ++-- drivers/clk/imx/Makefile | 5 ++--- drivers/clk/imx/clk-lpcg-scu.c | 1 + drivers/clk/imx/clk-scu.c | 5 +++++ 4 files changed, 10 insertions(+), 5 deletions(-)
