That's annoying, I thought I did build test the final changes. However, there's a mistake in the Makefile meaning that it wasn't building with no warning/error messages - it actually wasn't building at all! Sorry about that Thierry. I guess if you can build the driver, you've already fixed that? diff --git a/drivers/pwm/Makefile b/drivers/pwm/Makefile index 878333a..79665e3 100644 --- a/drivers/pwm/Makefile +++ b/drivers/pwm/Makefile @@ -20,7 +20,7 @@ obj-$(CONFIG_PWM_PXA) += pwm-pxa.o obj-$(CONFIG_PWM_RENESAS_TPU) += pwm-renesas-tpu.o obj-$(CONFIG_PWM_SAMSUNG) += pwm-samsung.o obj-$(CONFIG_PWM_SPEAR) += pwm-spear.o -obj-$(CONFIG_PWM_STI) += pwm-st.o +obj-$(CONFIG_PWM_STI) += pwm-sti.o obj-$(CONFIG_PWM_TEGRA) += pwm-tegra.o obj-$(CONFIG_PWM_TIECAP) += pwm-tiecap.o obj-$(CONFIG_PWM_TIEHRPWM) += pwm-tiehrpwm.o After that change, I can see that you're absolutely correct: CC drivers/pwm/pwm-sti.o ../drivers/pwm/pwm-sti.c: In function ‘sti_pwm_config’: ../drivers/pwm/pwm-sti.c:202:3: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘int’ [-Wformat=] dev_dbg(dev, "prescale:%u, period:%lu, duty:%i, pwmvalx:%u\n", ^ ../drivers/pwm/pwm-sti.c: In function ‘sti_pwm_probe’: ../drivers/pwm/pwm-sti.c:352:31: error: ‘np’ undeclared pc->clk = of_clk_get_by_name(np, "pwm"); ^ Sorry for the fuss. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
