dc3287206a mmc: sdhci: fix DMA configure compatibility issue when 64bit DMA mode is used.
commit 20dbd07ef0a8bc29eb03d6a95258ac8934cbe52d upstream.

Bayhub SD host has hardware limitation:
1.The upper 32bit address is inhibited to be written at SD Host Register
  [03E][13]=0 (32bits addressing) mode, is admitted to be written only at
  SD Host Register [03E][13]=1 (64bits addressing) mode.
2.Because of above item#1, need to configure SD Host Register [03E][13] to
  1(64bits addressing mode) before set 64bit ADMA system address's higher
  32bits SD Host Register [05F~05C] if 64 bits addressing mode is used.

The hardware limitation is reasonable for below reasons:
1.Normal flow should set DMA working mode first, then do
  DMA-transfer-related configuration, such as system address.
2.The hardware limitation may avoid the software to configure wrong higher
  32bit address at 32bits addressing mode although it is redundant.

The change that set 32bits/64bits addressing mode before set ADMA address,
  has no side-effect to other host IPs for below reason:
The setting order is reasonable and standard: DMA Mode setting first and
  then DMA address setting. It meets all DMA setting sequence.

191628e2d9 mmc: mmci: Set PROBE_PREFER_ASYNCHRONOUS
commit 3108eb2e8aa7e955a9dd3a4c1bf19a7898961822 upstream.

All mmc host drivers should have the asynchronous probe option enabled, but
it seems like we failed to set it for mmci, so let's do that now.

02c8c2b5f6 mmc: core: disable TRIM on Micron MTFC4GACAJCN-1M
commit dbfbddcddcebc9ce8a08757708d4e4a99d238e44 upstream.

It seems that Micron MTFC4GACAJCN-1M despite advertising TRIM support does
not work when the core is trying to use REQ_OP_WRITE_ZEROES.

We are seeing the following errors in OpenWrt under 6.1 on Qnap Qhora 301W
that we did not previously have and tracked it down to REQ_OP_WRITE_ZEROES:
[   18.085950] I/O error, dev loop0, sector 596 op 0x9:(WRITE_ZEROES) flags 0x800 phys_seg 0 prio class 2

Disabling TRIM makes the error go away, so lets add a quirk for this eMMC
to disable TRIM.

6f9708e5c1 mmc: core: disable TRIM on Kingston EMMC04G-M627
commit f1738a1f816233e6dfc2407f24a31d596643fd90 upstream.

It seems that Kingston EMMC04G-M627 despite advertising TRIM support does
not work when the core is trying to use REQ_OP_WRITE_ZEROES.

We are seeing I/O errors in OpenWrt under 6.1 on Zyxel NBG7815 that we did
not previously have and tracked it down to REQ_OP_WRITE_ZEROES.

Trying to use fstrim seems to also throw errors like:
[93010.835112] I/O error, dev loop0, sector 16902 op 0x3:(DISCARD) flags 0x800 phys_seg 1 prio class 2

Disabling TRIM makes the error go away, so lets add a quirk for this eMMC
to disable TRIM.

1be288fd3b mmc: meson-gx: remove redundant mmc_request_done() call from irq context
commit 3c40eb8145325b0f5b93b8a169146078cb2c49d6 upstream.

The call to mmc_request_done() can schedule, so it must not be called
from irq context. Wake the irq thread if it needs to be called, and let
its existing logic do its work.

Fixes the following kernel bug, which appears when running an RT patched

commit e6f9e590b72e12bbb86b1b8be7e1981f357392ad upstream.

While SDHCI claims to support 64-bit DMA on MSM8916 it does not seem to
be properly functional. It is not immediately obvious because SDHCI is
usually used with IOMMU bypassed on this SoC, and all physical memory
has 32-bit addresses. But when trying to enable the IOMMU it quickly
fails with an error such as the following:

Looking closely it's obvious that only the 32-bit part of the address
(0xfffff200) arrives at the SMMU, the higher 16-bit (0xffff...) get
lost somewhere. This might not be a limitation of the SDHCI itself but
perhaps the bus/interconnect it is connected to, or even the connection
to the SMMU.

Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid
using 64-bit addresses.

e6dc6a9d0a mmc: block: ensure error propagation for non-blk
commit 003fb0a51162d940f25fc35e70b0996a12c9e08a upstream.

Requests to the mmc layer usually come through a block device IO.
The exceptions are the ioctl interface, RPMB chardev ioctl
and debugfs, which issue their own blk_mq requests through
blk_execute_rq and do not query the BLK_STS error but the
mmcblk-internal drv_op_result. This patch ensures that drv_op_result
defaults to an error and has to be overwritten by the operation
to be considered successful.

The behavior leads to a bug where the request never propagates
the error, e.g. by directly erroring out at mmc_blk_mq_issue_rq if
mmc_blk_part_switch fails. The ioctl caller of the rpmb chardev then
can never see an error (BLK_STS_IOERR, but drv_op_result is unchanged)
and thus may assume that their call executed successfully when it did not.

While always checking the blk_execute_rq return value would be
advised, let's eliminate the error by always setting
drv_op_result as -EIO to be overwritten on success (or other error)

6127e956c3 mmc: vub300: fix invalid response handling
commit a99d21cefd351c8aaa20b83a3c942340e5789d45 upstream.

We may get an empty response with zero length at the beginning of
the driver start and get following UBSAN error. Since there is no
content(SDRT_NONE) for the response, just return and skip the response
handling to avoid this problem.

Test pass : SDIO wifi throughput test with this patch

[ Upstream commit 0dd8316037a2a6d85b2be208bef9991de7b42170 ]

If spec_reg is equal to 'SDHCI_PRESENT_STATE', esdhc_readl_fixup()
fixes up register value and returns it immediately. As a result, the
further block
(spec_reg == SDHCI_PRESENT_STATE)
    &&(esdhc->quirk_ignore_data_inhibit == true),
is never executed.

The patch merges the second block into the first one.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

980d4e70c7 mmc: atmel-mci: fix race between stop command and start of next command
[ Upstream commit eca5bd666b0aa7dc0bca63292e4778968241134e ]

This commit fixes a race between completion of stop command and start of a
new command.
Previously the command ready interrupt was enabled before stop command
was written to the command register. This caused the command ready
interrupt to fire immediately since the CMDRDY flag is asserted constantly
while there is no command in progress.
Consequently the command state machine will immediately advance to the
next state when the tasklet function is executed again, no matter
actual completion state of the stop command.
Thus a new command can then be dispatched immediately, interrupting and
corrupting the stop command on the CMD line.
Fix that by dropping the command ready interrupt enable before calling
atmci_send_stop_cmd. atmci_send_stop_cmd does already enable the
command ready interrupt, no further writes to ATMCI_IER are necessary.

30716d9f0f mmc: sdio: fix possible resource leaks in some error paths
commit 605d9fb9556f8f5fb4566f4df1480f280f308ded upstream.

If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can
not release the resources, because the sdio function is not presented
in these two cases, it won't call of_node_put() or put_device().

To fix these leaks, make sdio_func_present() only control whether
device_del() needs to be called or not, then always call of_node_put()
and put_device().

In error case in sdio_init_func(), the reference of 'card->dev' is
not get, to avoid redundant put in sdio_free_func_cis(), move the
get_device() to sdio_alloc_func() and put_device() to sdio_release_func(),
it can keep the get/put function be balanced.

Without this patch, while doing fault inject test, it can get the
following leak reports, after this fix, the leak is gone.

[ Upstream commit b38a20f29a49ae04d23750d104b25400b792b98c ]

mmc_add_host() may return error, if we ignore its return value,
it will lead two issues:
1. The memory that allocated in mmc_alloc_host() is leaked.
2. In the remove() path, mmc_remove_host() will be called to
   delete device, but it's not added yet, it will lead a kernel
   crash because of null-ptr-deref in device_del().

So fix this by checking the return value and goto error path which
will call mmc_free_host().

940b774069 mmc: sdhci: Fix voltage switch delay
commit c981cdfb9925f64a364f13c2b4f98f877308a408 upstream.

Commit 20b92a30b561 ("mmc: sdhci: update signal voltage switch code")
removed voltage switch delays from sdhci because mmc core had been
enhanced to support them. However that assumed that sdhci_set_ios()
did a single clock change, which it did not, and so the delays in mmc
core, which should have come after the first clock change, were not
effective.

Fix by avoiding re-configuring UHS and preset settings when the clock
is turning on and the settings have not changed. That then also avoids
the associated clock changes, so that then sdhci_set_ios() does a single
clock change when voltage switching, and the mmc core delays become
effective.

To do that has meant keeping track of driver strength (host->drv_type),
and cases of reinitialization (host->reinit_uhs).

Note also, the 'turning_on_clk' restriction should not be necessary
but is done to minimize the impact of the change on stable kernels.

commit a3cab1d2132474969871b5d7f915c5c0167b48b0 upstream.

With the current logic the "failed to exit halt state" error would be
shown even if any other bit than CQHCI_HALT was set in the CQHCI_CTL
register, since the right hand side is always true. Fix this by using
the correct operator (bit-wise instead of logical AND) to only check for
the halt bit flag, which was obviously intended here.

57112da86b mmc: sdhci-brcmstb: Fix SDHCI_RESET_ALL for CQHCI
[ Upstream commit 56baa208f91061ff27ec2d93fbc483f624d373b4 ]

[[ NOTE: this is completely untested by the author, but included solely
    because, as noted in commit df57d73276b8 ("mmc: sdhci-pci: Fix
    SDHCI_RESET_ALL for CQHCI for Intel GLK-based controllers"), "other
    drivers using CQHCI might benefit from a similar change, if they
    also have CQHCI reset by SDHCI_RESET_ALL." We've now seen the same
    bug on at least MSM, Arasan, and Intel hardware. ]]

SDHCI_RESET_ALL resets will reset the hardware CQE state, but we aren't
tracking that properly in software. When out of sync, we may trigger
various timeouts.

It's not typical to perform resets while CQE is enabled, but this may
occur in some suspend or error recovery scenarios.

Include this fix by way of the new sdhci_and_cqhci_reset() helper.

I only patch the bcm7216 variant even though others potentially *could*
provide the 'supports-cqe' property (and thus enable CQHCI), because
d46ba2d17f90 ("mmc: sdhci-brcmstb: Add support for Command Queuing
(CQE)") and some Broadcom folks confirm that only the 7216 variant
actually supports it.

This patch depends on (and should not compile without) the patch
entitled "mmc: cqhci: Provide helper for resetting both SDHCI and
CQHCI".
