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-$(CONFIG_PWM_PXA) +=3D pwm-pxa.o obj-$(CONFIG_PWM_RENESAS_TPU) +=3D pwm-renesas-tpu.o obj-$(CONFIG_PWM_SAMSUNG) +=3D pwm-samsung.o obj-$(CONFIG_PWM_SPEAR) +=3D pwm-spear.o -obj-$(CONFIG_PWM_STI) +=3D pwm-st.o +obj-$(CONFIG_PWM_STI) +=3D pwm-sti.o obj-$(CONFIG_PWM_TEGRA) +=3D pwm-tegra.o obj-$(CONFIG_PWM_TIECAP) +=3D pwm-tiecap.o obj-$(CONFIG_PWM_TIEHRPWM) +=3D pwm-tiehrpwm.o After that change, I can see that you're absolutely correct: CC drivers/pwm/pwm-sti.o =2E./drivers/pwm/pwm-sti.c: In function =E2=80=98sti_pwm_config=E2=80=99= : =2E./drivers/pwm/pwm-sti.c:202:3: warning: format =E2=80=98%lu=E2=80=99 expects argument of type =E2=80=98long u= nsigned int=E2=80=99, but argument 5 has type =E2=80=98int=E2=80=99 [-Wformat=3D] dev_dbg(dev, "prescale:%u, period:%lu, duty:%i, pwmvalx:%u\n", ^ =2E./drivers/pwm/pwm-sti.c: In function =E2=80=98sti_pwm_probe=E2=80=99= : =2E./drivers/pwm/pwm-sti.c:352:31: error: =E2=80=98np=E2=80=99 undeclar= ed=20 pc->clk =3D of_clk_get_by_name(np, "pwm"); ^ Sorry for the fuss. --=20 Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org =E2=94=82 Open source software for ARM SoCs =46ollow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe devicetree" i= n the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
