In bypass charging operation, the charger bypasses the charging path around the integrated converter allowing for a "smart" wall adaptor to perform the power conversion externally. This operational mode is critical for the USB PPS standard of power adaptors and is becoming a common feature in modern charging ICs such as: - BQ25980 - BQ25975 - BQ25960 - LN8000 - LN8410 Signed-off-by: Ricardo Rivera-Matos --- drivers/power/supply/power_supply_sysfs.c | 1 + include/linux/power_supply.h | 1 + 2 files changed, 2 insertions(+) diff --git a/drivers/power/supply/power_supply_sysfs.c b/drivers/power/supply/power_supply_sysfs.c index 6ac88fbee3cb..52c909bae457 100644 --- a/drivers/power/supply/power_supply_sysfs.c +++ b/drivers/power/supply/power_supply_sysfs.c @@ -89,6 +89,7 @@ static const char * const POWER_SUPPLY_CHARGE_TYPE_TEXT[] = { [POWER_SUPPLY_CHARGE_TYPE_ADAPTIVE] = "Adaptive", [POWER_SUPPLY_CHARGE_TYPE_CUSTOM] = "Custom", [POWER_SUPPLY_CHARGE_TYPE_LONGLIFE] = "Long Life", + [POWER_SUPPLY_CHARGE_TYPE_BYPASS] = "Bypass", }; static const char * const POWER_SUPPLY_HEALTH_TEXT[] = { diff --git a/include/linux/power_supply.h b/include/linux/power_supply.h index 86b4d5c4dab9..164779bc7e8f 100644 --- a/include/linux/power_supply.h +++ b/include/linux/power_supply.h @@ -49,6 +49,7 @@ enum { POWER_SUPPLY_CHARGE_TYPE_ADAPTIVE, /* dynamically adjusted speed */ POWER_SUPPLY_CHARGE_TYPE_CUSTOM, /* use CHARGE_CONTROL_* props */ POWER_SUPPLY_CHARGE_TYPE_LONGLIFE, /* slow speed, longer life */ + POWER_SUPPLY_CHARGE_TYPE_BYPASS, /* bypassing the charger */ }; enum { From patchwork Thu Feb 10 15:41:08 2022 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Ricardo Rivera-Matos X-Patchwork-Id: 541999 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 vger.kernel.org (vger.kernel.org [23.128.96.18]) by smtp.lore.kernel.org (Postfix) with ESMTP id 8DE68C433F5 for ; Thu, 10 Feb 2022 16:26:17 +0000 (UTC) Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S244175AbiBJQ0M (ORCPT ); Thu, 10 Feb 2022 11:26:12 -0500 Received: from mxb-00190b01.gslb.pphosted.com ([23.128.96.19]:41508 "EHLO lindbergh.monkeyblade.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S244167AbiBJQ0L (ORCPT ); Thu, 10 Feb 2022 11:26:11 -0500 Received: from mx0b-001ae601.pphosted.com (mx0b-001ae601.pphosted.com [67.231.152.168]) by lindbergh.monkeyblade.net (Postfix) with ESMTPS id 54B2DC26; Thu, 10 Feb 2022 08:26:11 -0800 (PST) Received: from pps.filterd (m0077474.ppops.net [127.0.0.1]) by mx0b-001ae601.pphosted.com (8.16.1.2/8.16.1.2) with ESMTP id 21AEBMiL025584; Thu, 10 Feb 2022 09:41:22 -0600 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=cirrus.com; h=from : to : cc : subject : date : message-id : in-reply-to : references : mime-version : content-transfer-encoding : content-type; s=PODMain02222019; bh=iAIOic3fs3DHgtceBaD28ld8RhX+XmG05O99KFICyHU=; b=OPz9mg1lCGDZFcdrjNWJ1hjxWGEdoO1jB+ngD8AWBqiUWuBULOfNxyhbtIl1s1bRC+nE WUDLJ+HsoQkkmvaO36rYOsztpW7kGyiDfTMtD8INGF1z8RlZlffHA+jeLN6xLvbRKwFh n44n9bI/jQ0dNoYlV2Md7EJIaZ5TtHgctrcwYSf6ICy8tue/hZ7o67P11En6yDEvrbHf 4nYHzGr6NDRrfIRffHjJGE5Q646xsPaSr/Z099XvqFKynhUZvGSt1/Kqr1iDdAV4TZzT 7X0SotbkfJPF7NEaT0/Je3rlImax2cNFpOAN2rktjeVbfZF10boLWI/zwSrY/jPVvi+p wg== Received: from ediex01.ad.cirrus.com ([84.19.233.68]) by mx0b-001ae601.pphosted.com (PPS) with ESMTPS id 3e4detskyx-2 (version=TLSv1.2 cipher=ECDHE-RSA-AES128-GCM-SHA256 bits=128 verify=NOT); Thu, 10 Feb 2022 09:41:21 -0600 Received: from EDIEX01.ad.cirrus.com (198.61.84.80) by EDIEX01.ad.cirrus.com (198.61.84.80) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256) id 15.1.2375.18; Thu, 10 Feb 2022 15:41:20 +0000 Received: from ediswmail.ad.cirrus.com (198.61.86.93) by EDIEX01.ad.cirrus.com (198.61.84.80) with Microsoft SMTP Server id 15.1.2375.18 via Frontend Transport; Thu, 10 Feb 2022 15:41:20 +0000 Received: from ricardo-lws.crystal.cirrus.com (ricardo-lws.ad.cirrus.com [141.131.206.19]) by ediswmail.ad.cirrus.com (Postfix) with ESMTP id 10A532A1; Thu, 10 Feb 2022 15:41:19 +0000 (UTC) From: Ricardo Rivera-Matos To: , , , CC: Ricardo Rivera-Matos Subject: [RESEND v2 2/2] power: supply: bq25980: Implements POWER_SUPPLY_CHARGE_TYPE_BYPASS Date: Thu, 10 Feb 2022 09:41:08 -0600 Message-ID: <20220210154108.641369-3-rriveram@opensource.cirrus.com> X-Mailer: git-send-email 2.25.1 In-Reply-To: <20220210154108.641369-1-rriveram@opensource.cirrus.com> References: <20220210154108.641369-1-rriveram@opensource.cirrus.com> MIME-Version: 1.0 X-Proofpoint-GUID: feDhXOyhHV27GLGeJJQd63wmvEu18Zvo X-Proofpoint-ORIG-GUID: feDhXOyhHV27GLGeJJQd63wmvEu18Zvo X-Proofpoint-Spam-Reason: safe Precedence: bulk List-ID: X-Mailing-List: linux-pm@vger.kernel.org This patch remaps the bypass operation from POWER_SUPPLY_CHARGE_TYPE_FAST to POWER_SUPPLY_CHARGE_TYPE_BYPASS.
