From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tony Lindgren Subject: [PATCH 2/2] bus: ti-sysc: Add mcasp optional clocks flag Date: Thu, 15 Nov 2018 14:02:37 -0800 Message-ID: <20181115220237.32129-3-tony@atomide.com> References: <20181115220237.32129-1-tony@atomide.com> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: In-Reply-To: <20181115220237.32129-1-tony@atomide.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-omap@vger.kernel.org Cc: Dave Gerlach , Faiz Abbas , Greg Kroah-Hartman , Keerthy , Nishanth Menon , Suman Anna , Tero Kristo , linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org, Mark Rutland , Rob Herring List-Id: linux-omap@vger.kernel.org We have OPT_CLKS_NEEDED in legacy platform data, but it's missing from the ti-sysc driver for device tree based configuration. In order to pass OPT_CLKS_NEEDED quirk flag we need to update omap4 module data and add a new compatible for dra7 as the module layout is different from sysc_regbits_omap4_mcasp.
