Not really now that I think about it, especially since the correct default value should be zero: -- part of msm-4.19 -- bit = adreno_dev->highest_bank_bit ? adreno_dev->highest_bank_bit - 13 : 0; lower_bit = bit & 0x3; upper_bit = (bit >> 0x2) & 1; where adreno_dev->highest_bank_bit is read from the dt property "qcom,highest-bank-bit" Anyway, I should be able to verify it for all the SoCs which we support.
