    Subject[PATCH AUTOSEL 5.5 300/542] ARM: dts: meson8: use the actual frequency for the GPU's 182.1MHz OPP
    Date
    From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

    [ Upstream commit fe634a7a9a57fb736e39fb71aa9adc6448a90f94 ]

    The clock setup on Meson8 cannot achieve a Mali frequency of exactly
    182.15MHz. The vendor driver uses "FCLK_DIV7 / 2" for this frequency,
    which translates to 2550MHz / 7 / 2 = 182142857Hz.
    Update the GPU operating point to that specific frequency to not confuse
    myself when comparing the frequency from the .dts with the actual clock
    rate on the system.

    Fixes: 7d3f6b536e72c9 ("ARM: dts: meson8: add the Mali-450 MP6 GPU")
