Subject: [PATCH 22/33] fsi: aspeed: Use common master error handler
Date: Thu, 15 Feb 2024 16:07:48 -0600 [thread overview]
Message-ID: <20240215220759.976998-23-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240215220759.976998-1-eajames@linux.ibm.com>
This will do the correct mmode manipulation to do the master
reset.
