    Subject[PATCH 4.4 001/158] MIPS: ath79: fix ar933x uart parity mode
    Date
    [ 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.
