605466fcf4 mmc: sdhci: Do not lock spinlock around mmc_gpio_get_ro()
commit ab069ce125965a5e282f7b53b86aee76ab32975c upstream.

sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.

However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().

So remove the locking.

d9e8b0f56b mmc: sdhci: Do not invert write-protect twice
commit fbd64f902b93fe9658b855b9892ae59ef6ea22b9 upstream.

mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.

sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.

Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".

Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.

Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.

Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

f24f76f59f mmc: sdhci-pci: Convert PCIBIOS_* return codes to errnos
commit ebc4fc34eae8ddfbef49f2bdaced1bf4167ef80d upstream.

jmicron_pmos() and sdhci_pci_probe() use pci_{read,write}_config_byte()
that return PCIBIOS_* codes. The return code is then returned as is by
jmicron_probe() and sdhci_pci_probe(). Similarly, the return code is
also returned as is from jmicron_resume(). Both probe and resume
functions should return normal errnos.

Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning them the fix these issues.

63664389b6 mmc: core: Do not force a retune before RPMB switch
commit 67380251e8bbd3302c64fea07f95c31971b91c22 upstream.

Requesting a retune before switching to the RPMB partition has been
observed to cause CRC errors on the RPMB reads (-EILSEQ).

Since RPMB reads can not be retried, the clients would be directly
affected by the errors.

This commit disables the retune request prior to switching to the RPMB
partition: mmc_retune_pause() no longer triggers a retune before the
pause period begins.

This was verified with the sdhci-of-arasan driver (ZynqMP) configured
for HS200 using two separate eMMC cards (DG4064 and 064GB2). In both
cases, the error was easy to reproduce triggering every few tenths of
reads.

With this commit, systems that were utilizing OP-TEE to access RPMB
variables will experience an enhanced performance. Specifically, when
OP-TEE is configured to employ RPMB as a secure storage solution, it not
only writes the data but also the secure filesystem within the
partition. As a result, retrieving any variable involves multiple RPMB
reads, typically around five.

For context, on ZynqMP, each retune request consumed approximately
8ms. Consequently, reading any RPMB variable used to take at the very
minimum 40ms.

After droping the need to retune before switching to the RPMB partition,
this is no longer the case.

d7bc1877c1 mmc: core: Fix switch on gp3 partition
[ Upstream commit 4af59a8df5ea930038cd3355e822f5eedf4accc1 ]

Commit e7794c14fd73 ("mmc: rpmb: fixes pause retune on all RPMB
partitions.") added a mask check for 'part_type', but the mask used was
wrong leading to the code intended for rpmb also being executed for GP3.

On some MMCs (but not all) this would make gp3 partition inaccessible:

c180d65df8 mmc: tmio: avoid concurrent runs of mmc_request_done()
[ Upstream commit e8d1b41e69d72c62865bebe8f441163ec00b3d44 ]

With the to-be-fixed commit, the reset_work handler cleared 'host->mrq'
outside of the spinlock protected critical section. That leaves a small
race window during execution of 'tmio_mmc_reset()' where the done_work
handler could grab a pointer to the now invalid 'host->mrq'. Both would
use it to call mmc_request_done() causing problems (see link below).

However, 'host->mrq' cannot simply be cleared earlier inside the
critical section. That would allow new mrqs to come in asynchronously
while the actual reset of the controller still needs to be done. So,
like 'tmio_mmc_set_ios()', an ERR_PTR is used to prevent new mrqs from
coming in but still avoiding concurrency between work handlers.

9d660e5adf mmc: core: Fix eMMC initialization with 1-bit bus connection
commit ff3206d2186d84e4f77e1378ba1d225633f17b9b upstream.

Initializing an eMMC that's connected via a 1-bit bus is current failing,
if the HW (DT) informs that 4-bit bus is supported. In fact this is a
regression, as we were earlier capable of falling back to 1-bit mode, when
switching to 4/8-bit bus failed. Therefore, let's restore the behaviour.

f49f9e8027 mmc: core: Use mrq.sbc in close-ended ffu
commit 4d0c8d0aef6355660b6775d57ccd5d4ea2e15802 upstream.

Field Firmware Update (ffu) may use close-ended or open ended sequence.
Each such sequence is comprised of a write commands enclosed between 2
switch commands - to and from ffu mode. So for the close-ended case, it
will be: cmd6->cmd23-cmd25-cmd6.

Some host controllers however, get confused when multi-block rw is sent
without sbc, and may generate auto-cmd12 which breaks the ffu sequence.
I encountered  this issue while testing fwupd (github.com/fwupd/fwupd)
on HP Chromebook x2, a qualcomm based QC-7c, code name - strongbad.

Instead of a quirk, or hooking the request function of the msm ops,
it would be better to fix the ioctl handling and make it use mrq.sbc
instead of issuing SET_BLOCK_COUNT separately.

bfc3720ca8 mmc: rpmb: fixes pause retune on all RPMB partitions.
commit e7794c14fd73e5eb4a3e0ecaa5334d5a17377c50 upstream.

When RPMB was converted to a character device, it added support for
multiple RPMB partitions (Commit 97548575bef3 ("mmc: block: Convert RPMB to
a character device").

One of the changes in this commit was transforming the variable target_part
defined in __mmc_blk_ioctl_cmd into a bitmask. This inadvertently regressed
the validation check done in mmc_blk_part_switch_pre() and
mmc_blk_part_switch_post(), so let's fix it.

33cc97d249 mmc: cqhci: Fix task clearing in CQE error recovery
[ Upstream commit 1de1b77982e1a1df9707cb11f9b1789e6b8919d4 ]

If a task completion notification (TCN) is received when there is no
outstanding task, the cqhci driver issues a "spurious TCN" warning. This
was observed to happen right after CQE error recovery.

When an error interrupt is received the driver runs recovery logic.
It halts the controller, clears all pending tasks, and then re-enables
it. On some platforms, like Intel Jasper Lake, a stale task completion
event was observed, regardless of the CQHCI_CLEAR_ALL_TASKS bit being set.

This results in either:
a) Spurious TC completion event for an empty slot.
b) Corrupted data being passed up the stack, as a result of premature
   completion for a newly added task.

Rather than add a quirk for affected controllers, ensure tasks are cleared
by toggling CQHCI_ENABLE, which would happen anyway if
cqhci_clear_all_tasks() timed out. This is simpler and should be safe and
effective for all controllers.

During CQE error recovery, error-free data commands get requeued if there
is any data left to transfer, but non-data commands are completed even
though they have not been processed.  Requeue them instead.

Note the only non-data command is cache flush, which would have resulted in
a cache flush being lost if it was queued at the time of CQE recovery.

This reverts commit 84ee19bffc9306128cd0f1c650e89767079efeff.

The commit above made quirks with an OEMID fail to be applied, as they
were checking card->cid.oemid for the full 16 bits defined in MMC_FIXUP
macros but the field would only contain the bottom 8 bits.

eMMC v5.1A might have bogus values in OEMID's higher bits so another fix
will be made, but it has been decided to revert this until that is ready.

commit 84ee19bffc9306128cd0f1c650e89767079efeff upstream.

The OEMID is an 8-bit binary number rather than 16-bit as the current code
parses for. The OEMID occupies bits [111:104] in the CID register, see the
eMMC spec JESD84-B51 paragraph 7.2.3. It seems that the 16-bit comes from
the legacy MMC specs (v3.31 and before).

Let's fix the parsing by simply move to use 8-bit instead of 16-bit. This
means we ignore the impact on some of those old MMC cards that may be out
there, but on the other hand this shouldn't be a problem as the OEMID seems
not be an important feature for these cards.

au1xmmc is split somewhat awkwardly into the main mmc subsystem driver,

always built in.  The latter than call mmc_detect_change through
symbol_get.  Remove the use of symbol_get by requiring the driver
to be built in.  In the future the interrupt handlers for card
insert/eject detection should probably be moved into the main driver,
and which point it can be built modular again.

6875690b0e mmc: block: Fix in_flight[issue_type] value error
commit 4b430d4ac99750ee2ae2f893f1055c7af1ec3dc5 upstream.

For a completed request, after the mmc_blk_mq_complete_rq(mq, req)
function is executed, the bitmap_tags corresponding to the
request will be cleared, that is, the request will be regarded as
idle. If the request is acquired by a different type of process at
this time, the issue_type of the request may change. It further
caused the value of mq->in_flight[issue_type] to be abnormal,
and a large number of requests could not be sent.

p1:					      p2:
mmc_blk_mq_complete_rq
  blk_mq_free_request
					      blk_mq_get_request
					        blk_mq_rq_ctx_init
mmc_blk_mq_dec_in_flight
  mmc_issue_type(mq, req)

This strategy can ensure the consistency of issue_type
before and after executing mmc_blk_mq_complete_rq.

The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream.  Since commit ce753ad1549c ("platform: finally disallow IRQ0
in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs,
so we now can safely ignore it...

[ Upstream commit 5def5c1c15bf22934ee227af85c1716762f3829f ]

Even if sdhci_pltfm_pmops is specified for PM, this driver doesn't apply
sdhci_pltfm, so the structure is not correctly referenced in PM functions.
This applies sdhci_pltfm to this driver to fix this issue.

- Call sdhci_pltfm_init() instead of sdhci_alloc_host() and
  other functions that covered by sdhci_pltfm.
- Move ops and quirks to sdhci_pltfm_data
- Replace sdhci_priv() with own private function sdhci_f_sdh30_priv().

4be68f1c70 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.

2f6c769946 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.
