This is what I want for pin control, and fixes an ages old issue that pin control has no intrinsic awareness of if a pin is muxed to a function providing GPIO. So patches applied! Any remaining code nitpicks can be fixed in-tree, I need this to be able to apply the much desired Broadcom STB driver, so this needs to go into -next now for cooking. I also want to strictify some drivers using this, bringing GPIO function awareness into them, which is a good thing! Yours, Linus Walleij
