Even if Nicolas thinks there may be users of the\nSPI interface with the existing DT binding, we can still decide\nto remove the MMIO interface entirely, as I first suggested.\n\nApparently the chips are still in production and are commonly\nused with microcontrollers, but the only reference I found\nabout using Linux with it is in a blog post that mentions\nan \"official\" driver from the manufacturer, with an\n(incompatible) compatible=\"w5000-wiz0\" DT binding:\n\nhttps://maker.wiznet.io/gavinchang/projects/linux-w5500-driver-and-use-1/\n\n Arnd","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=arndb.de header.i=@arndb.de header.a=rsa-sha256\n header.s=fm2 header.b=LuObU3N4;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=messagingengine.com header.i=@messagingengine.com\n header.a=rsa-sha256 header.s=fm2 header.b=YJL793Mr;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=vger.kernel.org\n (client-ip=172.234.253.10;
