From mboxrd@z Thu Jan 1 00:00:00 1970 From: Suman Anna Subject: [PATCH 2/3] hwspinlock/omap: Add support for TI K3 SoCs Date: Thu, 30 May 2019 21:13:20 -0500 Message-ID: <20190531021321.14025-3-s-anna@ti.com> References: <20190531021321.14025-1-s-anna@ti.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20190531021321.14025-1-s-anna@ti.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Bjorn Andersson , Rob Herring Cc: devicetree@vger.kernel.org, linux-omap@vger.kernel.org, linux-remoteproc@vger.kernel.org, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org A HwSpinlock IP is also present on the newer TI K3 AM65x and J721E family of SoCs within the Main NavSS sub-module. Reuse the existing OMAP Hwspinlock driver to extend the support for this IP on K3 AM65x SoCs as well. The IP has slightly different bit-fields in the SYSCONFIG and SYSSTATUS registers.
