commit 43592c8736 upstream.
Only wait for DRTO on reads, otherwise the driver hangs.
The driver prevents sending CMD12 on response errors like CRCs. According
to the comment this is because some cards have problems with this during
the UHS tuning sequence. Unfortunately this workaround currently also
applies for any command with data. On reads this will set the drto timer,
which then triggers after a while. On writes this will not set any timer
and the tasklet will not be scheduled again.
I cannot test for the UHS workarounds need, but even if so, it should at
most apply to reads. I have observed many hangs when CMD25 response
contained a CRC error. This patch fixes this without touching the actual
UHS tuning workaround.

[ Upstream commit 3ac5e45291 ]
For unexplained reasons, the prescaler register for this device needs to
be cleared (set to 1) while performing a data read or else the command
will hang. This does not appear to affect the real clock rate sent out
on the bus, so I assume it's purely to work around a hardware bug.
During normal operation, the prescaler is already set to 1, so nothing
needs to be done. However, in "initial mode" (which is used for sub-MHz
clock speeds, like the core sets while enumerating cards), it's set to
128 and so we need to reset it during data reads. We currently fail to
do this for long reads.
This has no functional affect on the driver's operation currently
written, as the MMC core always sets a clock above 1MHz before
attempting any long reads. However, the core could conceivably set any
clock speed at any time and the driver should still work, so I think
this fix is worthwhile.
I personally encountered this issue while performing data recovery on an
external chip. My connections had poor signal integrity, so I modified
the core code to reduce the clock speed. Without this change, I saw the
card enumerate but was unable to actually read any data.
Writes don't seem to work in the situation described above even with
this change (and even if the workaround is extended to encompass data
write commands). I was not able to find a way to get them working.

[ Upstream commit 25f8203b4b ]
When a Data CRC interrupt is received, the driver disables the DMA, then
sends the stop/abort command and then waits for Data Transfer Over.
However, sometimes, when a data CRC error is received in the middle of a
multi-block write transfer, the Data Transfer Over interrupt is never
received, and the driver hangs and never completes the request.
The driver sets the BMOD.SWR bit (SDMMC_IDMAC_SWRESET) when stopping the
DMA, but according to the manual CMD.STOP_ABORT_CMD should be programmed
"before assertion of SWR". Do these operations in the recommended
order. With this change the Data Transfer Over is always received
correctly in my tests.

commit d0244847f9 upstream.
When an eMMC device is being run in HS400 mode, any access to the
RPMB device will cause the error message "mmc1: Invalid UHS-I mode
selected". This happens as a result of tuning being disabled before
RPMB access and then re-enabled after the RPMB access is complete.
When tuning is re-enabled, the system has to switch from HS400
to HS200 to do the tuning and then back to HS400. As part of
sequence to switch from HS400 to HS200 the system is temporarily
put into HS mode. When switching to HS mode, sdhci_get_preset_value()
is called and does not have support for HS mode and prints the warning
message and returns the preset for SDR12. The fix is to add support
for MMC and SD HS modes to sdhci_get_preset_value().
This can be reproduced on any system running eMMC in HS400 mode
(not HS400ES) by using the "mmc" utility to run the following
command: "mmc rpmb read-counter /dev/mmcblk0rpmb".

A CMD11 is sent to the SD/SDIO card to start the voltage switch procedure
into 1.8V I/O. According to the SD spec a power cycle is needed of the
card, if it turns out that the CMD11 fails. Let's fix this, to allow a
retry of the initialization without the voltage switch, to succeed.
Note that, whether it makes sense to also retry with the voltage switch
after the power cycle is a bit more difficult to know. At this point, we
treat it like the CMD11 isn't supported and therefore we skip it when
retrying.

commit af3ed11932 upstream.
The code in mmc_spi_initsequence() tries to send a burst with
high chipselect and for this reason hardcodes the device into
SPI_CS_HIGH.
This is not good because the SPI_CS_HIGH flag indicates
logical "asserted" CS not always the physical level. In
some cases the signal is inverted in the GPIO library and
in that case SPI_CS_HIGH is already set, and enforcing
SPI_CS_HIGH again will actually drive it low.
Instead of hard-coding this, toggle the polarity so if the
default is LOW it goes high to assert chipselect but if it
is already high then toggle it low instead.

Pandora_wl1251_init_card was used to do special pdata based

v4.7 and later. A fix requires a device tree based mmc3 setup.
Therefore we move the special setup to omap_hsmmc.c instead
of calling some pdata supplied init_card function.
The new code checks for a DT child node compatible to wl1251
so it will not affect other MMC3 use cases.
Generally, this code was and still is a hack and should be
moved to mmc core to e.g. read such properties from optional
DT child nodes.

[ Upstream commit c894e33ddc ]
When switching from any MMC speed mode that requires 1.8v
(HS200, HS400 and HS400ES) to High Speed (HS) mode, the system
ends up configured for SDR12 with a 50MHz clock which is an illegal
mode.
This happens because the SDHCI_CTRL_VDD_180 bit in the
SDHCI_HOST_CONTROL2 register is left set and when this bit is
set, the speed mode is controlled by the SDHCI_CTRL_UHS field
in the SDHCI_HOST_CONTROL2 register. The SDHCI_CTRL_UHS field
will end up being set to 0 (SDR12) by sdhci_set_uhs_signaling()
because there is no UHS mode being set.
The fix is to change sdhci_set_uhs_signaling() to set the
SDHCI_CTRL_UHS field to SDR25 (which is the same as HS) for
any switch to HS mode.
This was found on a new eMMC controller that does strict checking
of the speed mode and the corresponding clock rate. It caused the
switch to HS400 mode to fail because part of the sequence to switch
to HS400 requires a switch from HS200 to HS before going to HS400.

The OCR register defines the supported range of VDD voltages for SD cards.
However, it has turned out that some SD cards reports an invalid voltage
range, for example having bit7 set.
When a host supports MMC_CAP2_FULL_PWR_CYCLE and some of the voltages from
the invalid VDD range, this triggers the core to run a power cycle of the
card to try to initialize it at the lowest common supported voltage.
Obviously this fails, since the card can't support it.
Let's fix this problem, by clearing invalid bits from the read OCR register
for SD cards, before proceeding with the VDD voltage negotiation.

In commit 46d179525a ("mmc: dw_mmc: Wait for data transfer after
response errors.") we fixed a tuning-induced hang that I saw when
stress testing tuning on certain SD cards. I won't re-hash that whole
commit, but the summary is that as a normal part of tuning you need to
deal with transfer errors and there were cases where these transfer
errors was putting my system into a bad state causing all future
transfers to fail. That commit fixed handling of the transfer errors
for me.
In downstream Chrome OS my fix landed and had the same behavior for
all SD/MMC commands. However, it looks like when the commit landed
upstream we limited it to only SD tuning commands. Presumably this
was to try to get around problems that Alim Akhtar reported on exynos
[1].
Unfortunately while stress testing reboots (and suspend/resume) on
some rk3288-based Chromebooks I found the same problem on the eMMC on
some of my Chromebooks (the ones with Hynix eMMC). Since the eMMC
tuning command is different (MMC_SEND_TUNING_BLOCK_HS200
vs. MMC_SEND_TUNING_BLOCK) we were basically getting back into the
same situation.
I'm hoping that whatever problems exynos was having in the past are
somehow magically fixed now and we can make the behavior the same for
all commands.

pwrseq_emmc.c implements a HW reset procedure for eMMC chip by driving a
GPIO line.
It registers the .reset() cb on mmc_pwrseq_ops and it registers a system
restart notification handler; both of them perform reset by unconditionally
calling gpiod_set_value().
If the eMMC reset line is tied to a GPIO controller whose driver can sleep
(i.e. I2C GPIO controller), then the kernel would spit warnings when trying
to reset the eMMC chip by means of .reset() mmc_pwrseq_ops cb (that is
exactly what I'm seeing during boot).
Furthermore, on system reset we would gets to the system restart
notification handler with disabled interrupts - local_irq_disable() is
called in machine_restart() at least on ARM/ARM64 - and we would be in
trouble when the GPIO driver tries to sleep (which indeed doesn't happen
here, likely because in my case the machine specific code doesn't call
do_kernel_restart(), I guess..).
This patch fixes the .reset() cb to make use of gpiod_set_value_cansleep(),
so that the eMMC gets reset on boot without complaints, while, since there
isn't that much we can do, we avoid register the restart handler if the
GPIO controller has a sleepy driver (and we spit a dev_notice() message to
let people know)..
This had been tested on a downstream 4.9 kernel with backported
commit 83f37ee7ba33 ("mmc: pwrseq: Add reset callback to the struct
mmc_pwrseq_ops") and commit ae60fb031cf2 ("mmc: core: Don't do eMMC HW

The SD Physical Layer Spec says the following: Since the SD Memory Card

Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101").
This change verifies the card has specified a bus width.
AMD SDHC Device 7806 can get into a bad state after a card disconnect
where anything transferred via the DATA lines will always result in a
zero filled buffer. Currently the driver will continue without error if
the HC is in this condition. A block device will be created, but reading
from it will result in a zero buffer. This makes it seem like the SD
device has been erased, when in actuality the data is never getting
copied from the DATA lines to the data buffer.
SCR is the first command in the SD initialization sequence that uses the
DATA lines. By checking that the response was invalid, we can abort
mounting the card.

[ Upstream commit 4bf7809966 ]
Existing data command CRC error handling is non-standard and does not work
with some Intel host controllers. Specifically, the assumption that the host
controller will continue operating normally after the error interrupt,
is not valid. Change the driver to handle the error in the same manner
as a data CRC error, taking care to ensure that the data line reset is
done for single or multi-block transfers, and it is done before
unmapping DMA.

[ Upstream commit 9ce58dd7d9 ]
Building with clang finds a mistaken __init tag:
WARNING: vmlinux.o(.text+0x5e4250): Section mismatch in reference from the function davinci_mmcsd_probe() to the function .init.text:init_mmcsd_host()
The function davinci_mmcsd_probe() references
the function __init init_mmcsd_host().
This is often because davinci_mmcsd_probe lacks a __init
annotation or the annotation of init_mmcsd_host is wrong.
