Export necessary functions and use "IS_ENABLED" instead of "ifdef" to support SCU pinctrl driver user and itself to be built as module. Signed-off-by: Anson Huang <redacted> --- Changes since V1: - Separate i.MX and i.MX SCU pinctrl driver to 2 patches; - Support building i.MX SCU pinctrl driver itself as module. --- drivers/pinctrl/freescale/Kconfig | 2 +- drivers/pinctrl/freescale/pinctrl-imx.h | 2 +- drivers/pinctrl/freescale/pinctrl-scu.c | 6 ++++++ 3 files changed, 8 insertions(+), 2 deletions(-)
