    Subject[PATCH 5.18 382/879] spi: cadence-quadspi: fix Direct Access Mode disable for SoCFPGA
    Date
    From: Ian Abbott <abbotti@mev.co.uk>

    [ Upstream commit f724c296f2f2cc3f9342b0fc26239635cbed856e ]

    The Cadence QSPI compatible string required for the SoCFPGA platform
    changed from the default "cdns,qspi-nor" to "intel,socfpga-qspi" with
    the introduction of an additional quirk in
    commit 98d948eb8331 ("spi: cadence-quadspi: fix write completion support").
    However, that change did not preserve the previously used
    quirk for this platform. Reinstate the `CQSPI_DISABLE_DAC_MODE` quirk
    for the SoCFPGA platform.

    Fixes: 98d948eb8331 ("spi: cadence-quadspi: fix write completion support")
