    Subject[PATCH 4.14 037/183] clk: sunxi-ng: v3s: Fix TCON reset de-assert bit
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    [ Upstream commit 5c59801f7018acba11b12de59017a3fcdcf7421d ]

    According to the datasheet and the reference code from Allwinner, the
    bit used to de-assert the TCON reset is bit 4, not bit 3.

    Fix it in the V3s CCU driver.
