That sounds crazy to me. Who is going to checkout the HWRNG tree and run-test it on it's own on all of the required hardware? No one. Agreed, subsystem trees should be bisectably (new word? :D) buildable as per my first rule above, but that's it. Per-subsystem repos are not designed to be tested for full-functionality orthogonally, that's the point of Stephen's -next tree. Please take my other points into consideration too. The kernel would be unmainatinable if we all stuck to your rule. No-one else has that rule, and for good reason. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
