Hi, You sent few patches independently of each other. If we did not ask, we would not get the idea why you need them. This is not how the Linux kernel development works. Instead, start preparing a proper patchset to achieve your goal. This patchset will contain multiple patches. It should go with a cover letter (see git format-patch) explaining why you do it. This way reviewers will know the big picture. The entire work should not break existing systems (see comments for IRQ combiner or pinctrl). You should consider how your change will affect existing systems. Best regards, Krzysztof
