mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019
This microSD card never clears Flush Cache bit after cache flush has been started in sd_flush_cache(). This leads e.g. to failure to mount file system. Add a quirk which disables the SD cache for this specific card from specific manufacturing date of 11/2019, since on newer dated cards from 05/2023 the cache flush works correctly. Fixes: 08ebf903af57 ("mmc: core: Fixup support for writeback-cache for eMMC and SD") Signed-off-by: Marek Vasut <marex@denx.de> Link: https://lore.kernel.org/r/20230620102713.7701-1-marex@denx.de Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
