From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ryder Lee Subject: [PATCH v4 4/6] dt-bindings: clock: mediatek: update audsys documentation to adapt MFD device Date: Tue, 6 Mar 2018 17:09:29 +0800 Message-ID: References: Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: Sender: linux-kernel-owner@vger.kernel.org To: Stephen Boyd , Rob Herring Cc: Mark Brown , Lee Jones , Matthias Brugger , linux-mediatek@lists.infradead.org, linux-kernel@vger.kernel.org, devicetree@vger.kernel.org, linux-arm-kernel@lists.infradead.org, linux-clk@vger.kernel.org, Garlic Tseng , Ryder Lee List-Id: linux-mediatek@lists.infradead.org The MediaTek audio hardware block that exposes functionalities that are handled by separate subsystems in the kernel. These functions are all mapped somewhere at 0x112xxxxx, and there are some control bits are mixed up with other functions within the same registers. This patch modifies example to illustrate child nodes.
