    SubjectRe: [PATCH v5 12/20] memory: mtk-smi: Add gals support
    From
    Date
    Hi Matthias,

    Gentle ping about this and the other mtk-smi part in this patchset.

    The memory part don't have its specific maintainer, normally we need
    SoC maintain's help. Thus, For this file(memory/mtk-smi.c), your review
    is needed before Joerg accept it.

    Appreciate in advance.
