K1 or K3? Aside from this K1-related patch, the rest of the series focuses on adding = support for the K3 SoC. I included the K1 header because I noticed it was missing in th= e upstream tree while working on the K3 support. It seems my attempt to 'clean up' K1 while adding K3 has caused unnecessary= confusion. Would you prefer me to remove the K1 patch from this series and submit it a= s a separate patch? - Troy From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from bombadil.infradead.org (bombadil.infradead.org [198.137.202.133]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.lore.kernel.org (Postfix) with ESMTPS id 3628910F3DDF for ;
