From e0db94fe87dacd72be0699adcc29e321db7f1689 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 27 May 2019 04:51:53 -0700 Subject: bus: ti-sysc: Make OCP reset work for sysstatus and sysconfig reset bits We've had minimal OCP softreset support in ti-sysc interconnect target module driver only used for MCAN driver so far. But it turns out that MCAN has the sysstatus register resetdone bit inverted compared to most other modules. Let's make OCP softreset work for other typical cases with reset status in sysstatus or sysconfig register so we can use the new functions for sysc_enable_module() and sysc_disable_module() without "ti,hwmods" property in the following patches.
