[ Upstream commit 09f164d393a6671e5ff8342ba6b3cb7fe3f20208 ]
The sdhci_omap is specific to older TI SoCs, update the
dependencies for those SoCs and compile testing. While we're
at it update the text to reflect the wider range of
supported TI SoCS the driver now supports.

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.

[ 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.

commit 174925d340aac55296318e43fd96c0e1d196e105 upstream.
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,
and callbacks in platform_data that sit under arch/mips/ and are
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.

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,

The driver overrides the error codes and IRQ0 returned by platform_get_irq()

permanently instead of the deferred probing. Switch to propagating the error
codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0

[ 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().

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.

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:

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)

commit 3f649ab728cda8038259d8f14492fe400fbab911 upstream.
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

[ 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.

commit 2265098fd6a6272fde3fd1be5761f2f5895bd99a upstream.
Timing Information in Datasheet assumes that HIGH_SPEED_ENA=1 should be
set for SDR12 and SDR25 modes. But sdhci_am654 driver clears
HIGH_SPEED_ENA register. Thus, Modify sdhci_am654 to not clear

[ 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.

commit cf4c9d2ac1e42c7d18b921bec39486896645b714 upstream.
If mmc_add_host() fails, it doesn't need to call mmc_remove_host(),
or it will cause null-ptr-deref, because of deleting a not added
device in mmc_remove_host().
To fix this, goto label 'fail_glue_init', if mmc_add_host() fails,
and change the label 'fail_add_host' to 'fail_gpiod_request'.

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 16e40e5b1e3c6646fd90d0c3186703d209216f03 ]
In current code, we add 1ms dealy after each tuning command for standard
tuning method. Adding this 1ms dealy is because USDHC default check the
CMD CRC and DATA line. If detect the CMD CRC, USDHC standard tuning
IC logic do not wait for the tuning data sending out by the card, trigger
the buffer read ready interrupt immediately, and step to next cycle. So
when next time the new tuning command send out by USDHC, card may still
not send out the tuning data of the upper command，then some eMMC cards
may stuck, can't response to any command, block the whole tuning procedure.
If do not check the CMD CRC for tuning, then do not has this issue. USDHC
will wait for the tuning data of each tuning command and check them. If the
tuning data pass the check, it also means the CMD line also okay for tuning.
So this patch disable the CMD CRC check for tuning, save some time for the
whole tuning procedure.
