    net: dsa: microchip: Always set regmap stride to 1 · a3aa6e65
    Marek Vasut authored
    The regmap stride is set to 1 for regmap describing 8bit registers already.
    However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This
    is not correct, as the switch protocol supports unaligned register reads
    and writes and the KSZ87xx even uses such unaligned register accesses to
    read e.g. MIB counter.
    This patch fixes MIB counter access on KSZ87xx.
