Subject: [PATCH 4.9 001/223] MIPS: ath79: fix ar933x uart parity mode
Date: Fri, 2 Aug 2019 11:33:46 +0200 [thread overview]
Message-ID: <20190802092238.781314964@linuxfoundation.org> (raw)
In-Reply-To: <20190802092238.692035242@linuxfoundation.org>
[ Upstream commit db13a5ba2732755cf13320f3987b77cf2a71e790 ]
While trying to get the uart with parity working I found setting even
parity enabled odd parity insted. Fix the register settings to match
the datasheet of AR9331.
A similar patch was created by 8devices, but not sent upstream.
