Subject: [PATCH 12/12] i3c: mipi-i3c-hci: Resume controller after aborted transfer
Date: Thu, 21 Sep 2023 08:57:04 +0300	[thread overview]
Message-ID: <20230921055704.1087277-13-jarkko.nikula@linux.intel.com> (raw)
In-Reply-To: <20230921055704.1087277-1-jarkko.nikula@linux.intel.com>

Host Controller goes to halt state after aborted transfer and needs to
be resumed by SW. Add this resuming to DMA mode code too.
