Just noticed that imx_clk_gate2 always sets both gates. This means, the RTC will be gated when going into low power modes. We might need to use a different gating when we want to use the RTC as wakeup source. But this would be part of the suspend/resume patchset... > > imx_check_clocks(clk, ARRAY_SIZE(clk)); > > diff --git a/include/dt-bindings/clock/vf610-clock.h > b/include/dt-bindings/clock/vf610-clock.h > index 801c0ac..979d24a 100644 > --- a/include/dt-bindings/clock/vf610-clock.h > +++ b/include/dt-bindings/clock/vf610-clock.h > @@ -192,6 +192,7 @@ > #define VF610_PLL5_BYPASS 179 > #define VF610_PLL6_BYPASS 180 > #define VF610_PLL7_BYPASS 181 > -#define VF610_CLK_END 182 > +#define VF610_CLK_SNVS 182 > +#define VF610_CLK_END 183 > > #endif /* __DT_BINDINGS_CLOCK_VF610_H */ Acked-By: Stefan Agner <[email protected]> -- Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
