From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tony Lindgren Subject: [PATCH 2/4] mfd: cpcap: Use handle_reread flag for interrupts Date: Thu, 16 Mar 2017 17:36:31 -0700 Message-ID: <20170317003633.7361-3-tony@atomide.com> References: <20170317003633.7361-1-tony@atomide.com> Return-path: In-Reply-To: <20170317003633.7361-1-tony@atomide.com> Sender: linux-kernel-owner@vger.kernel.org To: Mark Brown Cc: linux-kernel@vger.kernel.org, linux-omap@vger.kernel.org, Lee Jones , Marcel Partap , Michael Scott , Sebastian Reichel List-Id: linux-omap@vger.kernel.org On CPCAP we need to keep reading interrupts until there are no more interrupts. Otherwise the PMIC interrupt to the SoC will at some point stop toggling. This seems to happen because new CPCAP device interrupts show up while we're handling.
