I would prefer to keep it as is, I'm not adding a new driver in this series, just the binding documentation and doing some refactoring. So if I changed this now, the driver would need to be messed up with an additional code to support both 'gpios' and 'reset-gpios'. Are there any serious reasons to use this specific name ? It's not related to the reset signal DT bindings, is it ? -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
