mmc: core: Fix ambiguous TRIM and DISCARD arg

2022-12-08T10:30:19+00:00

commit 489d144563f23911262a652234b80c70c89c978b upstream. Clean up the MMC_TRIM_ARGS define that became ambiguous with DISCARD introduction. While at it, let's fix one usage where MMC_TRIM_ARGS falsely included DISCARD too.

mmc: core: Add SD card quirk for broken discard

2022-10-21T10:37:35+00:00

commit 07d2872bf4c864eb83d034263c155746a2fb7a3b upstream. Some SD-cards from Sandisk that are SDA-6.0 compliant reports they supports discard, while they actually don't. This might cause mk2fs to fail while trying to format the card and revert it to a read-only mode. To fix this problem, let's add a card quirk (MMC_QUIRK_BROKEN_SD_DISCARD) to indicate that we shall fall-back to use the legacy erase command instead.

mmc: core: Add support for SDIO wakeup interrupt

2022-07-26T14:58:31+00:00

If wakeup-source flag is set in host dts node, parse EAI information from SDIO CCCR interrupt externsion segment for in-band wakeup. If async interrupt is supported by SDIO card then enable it and set enable_async_irq flag in sdio_cccr structure to 1. The parse flow is implemented in sdio_read_cccr().

mmc: core: Use mmc_card_* macro and add a new for the sd_combo type

2022-07-13T10:44:41+00:00

Add mmc_card_sd_combo() macro for sd combo type card and use the mmc_card_* macro to simplify code instead of comparing card->type. Signed-off-by: Seunghui Lee Link: https://lore.kernel.org/r/20220713033635.28432-2-sh043.lee@samsung.com Signed-off-by: Ulf Hansson

mmc: improve API to make clear hw_reset callback is for cards

2022-04-26T12:05:20+00:00

To make it unambiguous that the hw_reset callback is for cards and not for controllers, we add 'card' to the callback name and convert all users in one go. We keep the argument as mmc_host, though, because the callback is used very early when mmc_card is not yet populated.
