commit 5e3486e64094c28a526543f1e8aa0d5964b7f02d upstream.
When 1-bit bus width is used with HS200/HS400 capabilities set,
mmc_select_hs200() returns 0 without actually switching. This
causes mmc_select_timing() to skip mmc_select_hs(), leaving eMMC
in legacy mode (26MHz) instead of High Speed SDR (52MHz).
Per JEDEC eMMC spec section 5.3.2, 1-bit mode supports High Speed
SDR. Drop incompatible HS200/HS400/UHS/DDR caps early so timing
selection falls through to mmc_select_hs() correctly.

commit 2b76e0cc7803e5ab561c875edaba7f6bbd87fbb0 upstream.
The GL9750 SD host controller has intermittent data corruption during
DMA write operations. The GM_BURST register's R_OSRC_Lmt field
(bits 17:16), which limits outstanding DMA read requests from system
memory, is not being cleared during initialization. The Windows driver
sets R_OSRC_Lmt to zero, limiting requests to the smallest unit.
Clear R_OSRC_Lmt to match the Windows driver behavior. This eliminates
write corruption verified with f3write/f3read tests while maintaining
DMA performance.

commit 3009738a855cf938bbfc9078bec725031ae623a4 upstream.
When operating in HS200 or HS400 timing modes, reducing the clock frequency
below 52MHz will lead to link broken as the Rockchip DWC MSHC controller
requires maintaining a minimum clock of 52MHz in these modes.
Add a check to prevent illegal clock reduction through debugfs:

commit b1f856b1727c2eaa4be2c6d7cd7a8ed052bbeb87 upstream.
According to the hardware programming guide, the clock frequency must
remain below 52MHz during the transition to HS400 mode.
However,in the current implementation, the timing is set to HS400 (a
DDR mode) before adjusting the clock. This causes the clock to double
prematurely to 104MHz during the transition phase, violating the
specification and potentially resulting in CRC errors or CMD timeouts.
This change ensures that clock doubling is avoided during intermediate
transitions and is applied only when the card requires a 200MHz clock
for HS400 operation.

[ Upstream commit db58532188ebf51d52b1d7693d9e94c76b926e9f ]
Many mobile phones feature multi-card tray designs, where the same
tray is used for both SD and SIM cards. If the SD card is placed
at the outermost location in the tray, the SIM card may come in
contact with SD card power-supply while removing the tray, possibly
resulting in SIM damage.
To prevent that, make sure the SD card is really inserted by reading
the Card Detect pin state. If it's not, turn off the power in
sdhci_msm_check_power_status() and also set the BUS_FAIL power state
on the controller as part of pwr_irq handling for BUS_ON request.

Then, the msdc_unprepare_data() checks MSDC_PREPARE_FLAG and calls
dma_unmap_sg() with unmapped pages. It causes a page fault.
To fix this problem, Do not set MSDC_PREPARE_FLAG if dma_map_sg()
fails because this is not prepared.

commit dcc3bcfc5b50c625b475dcc25d167b6b947a6637 upstream.
It has turned out the trying to strictly conform to the SDHCI specification
is causing problems. Let's revert and start over.

[ Upstream commit 31e75ed964582257f59156ce6a42860e1ae4cc39 ]
The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
lowered to less than 0.5V for a minimum of 1 ms when powering off a
card. Increase wait to 15 ms so that voltage has time to drain down
to 0.5V and cards can power off correctly. Issues with voltage drain
time were only observed on Apollo Lake and Bay Trail host controllers
so this fix is limited to those devices.

Set the MMC_CAP_NEED_RSP_BUSY capability for the sdhci-pxav3 host to

commit 3e68abf2b9cebe76c6cd4b1aca8e95cd671035a3 upstream.
For hs400(es) mode, the 'hs400-ds-delay' is typically configured in the
dts. However, some projects may only define 'mediatek,hs400-ds-dly3',
which can lead to initialization failures in hs400es mode. CMD13 reported
response crc error in the mmc_switch_status() just after switching to
hs400es mode.
[ 1.914038][ T82] mmc0: mmc_select_hs400es failed, error -84
[ 1.914954][ T82] mmc0: error -84 whilst initialising MMC card
Currently, the hs400_ds_dly3 value is set within the tuning function. This
means that the PAD_DS_DLY3 field is not configured before tuning process,
which is the reason for the above-mentioned CMD13 response crc error.
Move the PAD_DS_DLY3 field configuration into msdc_prepare_hs400_tuning(),
and add a value check of hs400_ds_delay to prevent overwriting by zero when
the 'hs400-ds-delay' is not set in the dts. In addition, since hs400(es)
only tune the PAD_DS_DLY1, the PAD_DS_DLY2_SEL bit should be cleared to
bypass it.

Currently, the sdhci-msm.c driver does not set the load to adjust

[ 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.
