Care to list what hardware and board revisions you're able to test deep sleep with? Seems like my am437x-evm is too old for this where the board layout does not match the schematics for removing a resistor to enable this. Just wondering if I can still enable tests for this somehow :) Regards, Tony 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 980F0C433EF for ; Thu, 21 Apr 2022 06:57:07 +0000 (UTC) DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=lists.infradead.org; s=bombadil.20210309; h=Sender: Content-Transfer-Encoding:Content-Type:List-Subscribe:List-Help:List-Post: List-Archive:List-Unsubscribe:List-Id:In-Reply-To:MIME-Version:References: Message-ID:Subject:Cc:To:From:Date:Reply-To:Content-ID:Content-Description: Resent-Date:Resent-From:Resent-Sender:Resent-To:Resent-Cc:Resent-Message-ID: List-Owner; bh=DtnFej5sPbzOOrsWsQnBUP0edmSK5eOhlSc5LxXGkgY=; b=VJIsYb6ENJ7/au 1p9YOU11qRKTqez2o0u6PlCmP4bldKIQ1YCBR0wNUDhG5N8PKWGfXFTIkjjyhsSIki5aHTDHeTpCB qiMz39axGCh15ntmq8Y3OK4eJw0KlayFYAFRKXwOg9945yJIn8ro1rLlMIXJ/C5Nygip1a+B7RUG/ hUjuBe28jsGl5CvKPpcGmsC03I06xrtf5B3/l9rcdoqP6aGBq2F3g1suqztHgz0D9pXfUIdiJwe0s MY0fFPy9cOgk/Tokkq0+axx+1uwRQa39GGTO78T35nunYYuNwUxhfUQUqykOALG7S8H+iVCAiM9kj uEAlmZCSuHRnzpqQa0mA==; Received: from localhost ([::1] helo=bombadil.infradead.org) by bombadil.infradead.org with esmtp (Exim 4.94.2 #2 (Red Hat Linux)) id 1nhQjY-00Bu1E-P3; Thu, 21 Apr 2022 06:56:08 +0000 Received: from muru.com ([72.249.23.125]) by bombadil.infradead.org with esmtp (Exim 4.94.2 #2 (Red Hat Linux)) id 1nhQjV-00Bu0X-P0 for linux-arm-kernel@lists.infradead.org; Thu, 21 Apr 2022 06:56:06 +0000 Received: from localhost (localhost [127.0.0.1]) by muru.com (Postfix) with ESMTPS id 034B68106; Thu, 21 Apr 2022 06:53:14 +0000 (UTC) Date: Thu, 21 Apr 2022 09:56:03 +0300 From: Tony Lindgren To: Drew Fustini Cc: Rob Herring , Krzysztof Kozlowski , Nishanth Menon , Santosh Shilimkar , Dave Gerlach , devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Subject: Re: [PATCH v3 0/2] soc: ti: wkup_m3_ipc: Add support for IO Isolation Message-ID: References: <20220414192722.2978837-1-dfustini@baylibre.com> MIME-Version: 1.0 Content-Disposition: inline In-Reply-To: <20220414192722.2978837-1-dfustini@baylibre.com> X-CRM114-Version: 20100106-BlameMichelson ( TRE 0.8.0 (BSD) ) MR-646709E3 X-CRM114-CacheID: sfid-20220420_235605_887547_DE00DD5A X-CRM114-Status: GOOD ( 12.08 ) X-BeenThere: linux-arm-kernel@lists.infradead.org X-Mailman-Version: 2.1.34 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org Hi, * Drew Fustini [220414 19:24]: > TI AM437x SoCs support isolation of the IOs so that control is taken > from the peripheral they are connected to and overridden by values > present in the control register for that pad.
