I wonder if this approach also works for\nBCMBCA given Haojian's comments on my previous patch attempts.\n\ndrivers/pinctrl/bcm/pinctrl-bcm4908.c would then be phased over\nto pinctrl-single, or does the MSB/LSB register layout create a\nproblem? If we always write 0 into MSB I guess we could just add\nsome quirk...\n\nYours,\nLinus Walleij","headers":{"Return-Path":"\n ","X-Original-To":["incoming@patchwork.ozlabs.org","linux-gpio@vger.kernel.org"],"Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=kernel.org header.i=@kernel.org header.a=rsa-sha256\n header.s=k20201202 header.b=YU4LpRfW;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=vger.kernel.org\n (client-ip=2600:3c09:e001:a7::12fc:5321;
