Hi Vadim, The quirk is standing for some workaround for those host that has some limitation that it cannot directly be applied with standard sdhci.c code, so that we add one quirk for it, which let it could use the sdhci.c.
Like the quirk as SDHCI_QUIRK_32BIT_DMA_ADDR, it indicate that some host has dma engine limitation that it must start from address with alignement. So if sdhci find caller set this quirk, it would follow corresponding workaround for it. There is no formal description for it as I could see.
