mmc: sdhci-msm: Correctly set the load for the regulator

2025-02-17T08:40:09+00:00

[ Upstream commit 20a0c37e44063997391430c4ae09973e9cbc3911 ]

Qualcomm regulator supports two power supply modes: HPM and LPM.
Currently, the sdhci-msm.c driver does not set the load to adjust
the current for eMMC and SD. If the regulator dont't set correct
load in LPM state, it will lead to the inability to properly
initialize eMMC and SD.

Set the correct regulator current for eMMC and SD to ensure that the
device can work normally even when the regulator is in LPM.

mmc: core: Respect quirk_max_rate for non-UHS SDIO card

2025-02-17T08:40:07+00:00

[ Upstream commit a2a44f8da29352f76c99c6904ee652911b8dc7dd ]

The card-quirk was added to limit the clock-rate for a card with UHS-mode
support, although let's respect the quirk for non-UHS mode too, to make the
behaviour consistent.

mmc: sdhci-msm: fix crypto key eviction

2025-01-09T12:31:54+00:00

commit 8d90a86ed053226a297ce062f4d9f4f521e05c4c upstream.

Commit c7eed31e235c ("mmc: sdhci-msm: Switch to the new ICE API")
introduced an incorrect check of the algorithm ID into the key eviction
path, and thus qcom_ice_evict_key() is no longer ever called.  Fix it.

[ Upstream commit 4dede2b76f4a760e948e1a49b1520881cb459bd3 ]

Enable SDHCI_QUIRK_NO_LED for i.MX7ULP, i.MX8MM, i.MX8QXP and
i.MXRT1050. Even there is LCTL register bit, there is no IOMUX PAD
for it. So there is no sense to enable LED for SDHCI for these SoCs.

mmc: core: Add SD card quirk for broken poweroff notification

2024-12-14T19:00:00+00:00

[ Upstream commit cd068d51594d9635bf6688fc78717572b78bce6a ]

GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that
they support poweroff notification and cache, but they are not working
correctly.

Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff
Notification Ready bit also never gets set to 1 within 1 second from the
end of busy of CMD49 in sd_poweroff_notify().

This leads to I/O error and runtime PM error state.

I observed that the same card manufactured on 01/2024 works as expected.

This problem seems similar to the Kingston cards fixed with
commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston
Canvas Go Plus from 11/2019") and should be handled using quirks.

CID for the problematic card is here.
12345641535443002000000145016200

Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now,
but would like comments on what naming is appropriate because MID list
is not public and not sure it's right.

mmc: core: Further prevent card detect during shutdown

2024-12-14T18:59:57+00:00

commit 87a0d90fcd31c0f36da0332428c9e1a1e0f97432 upstream.

Disabling card detect from the host's ->shutdown_pre() callback turned out
to not be the complete solution. More precisely, beyond the point when the
mmc_bus->shutdown() has been called, to gracefully power off the card, we
need to prevent card detect. Otherwise the mmc_rescan work may poll for the
card with a CMD13, to see if it's still alive, which then will fail and
hang as the card has already been powered off.

To fix this problem, let's disable mmc_rescan prior to power off the card
during shutdown.

mmc: sdhci-pci: Add DMI quirk for missing CD GPIO on Vexia Edu Atla 10 tablet

2024-12-14T18:59:57+00:00

commit 7f0fa47ceebcff0e3591bb7e32a71a2cd7846149 upstream.

The Vexia Edu Atla 10 tablet distributed to schools in the Spanish
Andalucía region has no ACPI fwnode associated with the SDHCI controller
for its microsd-slot and thus has no ACPI GPIO resource info.

This causes the following error to be logged and the slot to not work:
[   10.572113] sdhci-pci 0000:00:12.0: failed to setup card detect gpio

Add a DMI quirk table for providing gpiod_lookup_tables with manually
provided CD GPIO info and use this DMI table to provide the CD GPIO info
on this tablet. This fixes the microsd-slot not working.

mmc: mtk-sd: Fix MMC_CAP2_CRYPTO flag setting

2024-12-14T18:59:43+00:00

[ Upstream commit 2508925fb346661bad9f50b497d7ac7d0b6085d0 ]

Currently, the MMC_CAP2_CRYPTO flag is set by default for eMMC hosts.
However, this flag should not be set for hosts that do not support inline
encryption.

The 'crypto' clock, as described in the documentation, is used for data
encryption and decryption. Therefore, only hosts that are configured with
this 'crypto' clock should have the MMC_CAP2_CRYPTO flag set.
