Subject: [PATCH AUTOSEL 4.14 14/33] mailbox: bcm-flexrm-mailbox: Fix FlexRM ring flush timeout issue
Date: Wed, 13 Mar 2019 15:14:47 -0400 [thread overview]
Message-ID: <20190313191506.159677-14-sashal@kernel.org> (raw)
In-Reply-To: <20190313191506.159677-1-sashal@kernel.org>
From: Rayagonda Kokatanur <rayagonda.kokatanur@broadcom.com>
[ Upstream commit d7bf31a0f85faaf63c63c39d55154825a1eaaea9 ]
RING_CONTROL reg was not written due to wrong address, hence all
the subsequent ring flush was timing out.
Fixes: a371c10ea4b3 ("mailbox: bcm-flexrm-mailbox: Fix FlexRM ring flush sequence")
