From 6fa154e282f9c86ff3e2f8df478f1df92881a6e2 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Thu, 30 May 2019 21:13:20 -0500 Subject: [PATCH] hwspinlock/omap: Add support for TI K3 SoCs 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.
