    Subject[PATCH AUTOSEL 4.19 153/167] i2c: at91: fix clk_offset for sama5d2
    Date
    From: Michał Mirosław <mirq-linux@rere.qmqm.pl>

    [ Upstream commit b1ac6704493fa14b5dc19eb6b69a73932361a131 ]

    In SAMA5D2 datasheet, TWIHS_CWGR register rescription mentions clock
    offset of 3 cycles (compared to 4 in eg. SAMA5D3).

    Cc: stable@vger.kernel.org # 5.2.x
    [needs applying to i2c-at91.c instead for earlier kernels]
    Fixes: 0ef6f3213dac ("i2c: at91: add support for new alternative command mode")
