[ Upstream commit 171a93182eccd6e6835d2c86b40787f9f832efaa ]
Clang gives a warning when compiling pata_legacy.c with 'make W=1' about
the 'rt' local variable in pdc20230_set_piomode() being set but unused.
Quite obviously, there is an outb() call missing to write back the updated
variable. Moreover, checking the docs by Petr Soucek revealed that bitwise
AND should have been done with a negated timing mask and the master/slave
timing masks were swapped while updating...

[ Upstream commit 3c132ea6508b34956e5ed88d04936983ec230601 ]
Having greater than AHCI_MAX_PORTS (32) ports detected isn't that critical
from the further AHCI-platform initialization point of view since
exceeding the ports upper limit will cause allocating more resources than
will be used afterwards. But detecting too many child DT-nodes doesn't
seem right since it's very unlikely to have it on an ordinary platform. In
accordance with the AHCI specification there can't be more than 32 ports
implemented at least due to having the CAP.NP field of 5 bits wide and the
PI register of dword size. Thus if such situation is found the DTB must
have been corrupted and the data read from it shouldn't be reliable. Let's
consider that as an erroneous situation and halt further resources
allocation.
Note it's logically more correct to have the nports set only after the
initialization value is checked for being sane. So while at it let's make
sure nports is assigned with a correct value.

commit ea08aec7e77bfd6599489ec430f9f859ab84575a upstream.
Commit 1527f69204fe ("ata: ahci: Add Green Sardine vendor ID as
board_ahci_mobile") added an explicit entry for AMD Green Sardine
AHCI controller using the board_ahci_mobile configuration (this
configuration has later been renamed to board_ahci_low_power).
The board_ahci_low_power configuration enables support for low power
modes.
This explicit entry takes precedence over the generic AHCI controller
entry, which does not enable support for low power modes.
Therefore, when commit 1527f69204fe ("ata: ahci: Add Green Sardine
vendor ID as board_ahci_mobile") was backported to stable kernels,
it make some Pioneer optical drives, which was working perfectly fine
before the commit was backported, stop working.
The real problem is that the Pioneer optical drives do not handle low
power modes correctly. If these optical drives would have been tested
on another AHCI controller using the board_ahci_low_power configuration,
this issue would have been detected earlier.
Unfortunately, the board_ahci_low_power configuration is only used in
less than 15% of the total AHCI controller entries, so many devices
have never been tested with an AHCI controller with low power modes.

commit 72aad489f992871e908ff6d9055b26c6366fb864 upstream.
The {dma|pio}_mode sysfs files are incorrectly documented as having a
list of the supported DMA/PIO transfer modes, while the corresponding
fields of the *struct* ata_device hold the transfer mode IDs, not masks.
To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfs
files are handled by the ata_bitfield_name_match() macro which leads to
reading such kind of nonsense from them:
$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4,
XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1,
XFER_PIO_0
Using the correct ata_bitfield_name_search() macro fixes that:
$ cat /sys/class/ata_device/dev3.0/pio_mode
XFER_PIO_4
While fixing the file documentation, somewhat reword the {dma|pio}_mode
file doc and add a note about being mostly useful for PATA devices to
the xfer_mode file doc...

This is because sata_dwc_dma_xfer_complete() NULLs the
dma_pending's next neighbour "chan" (a *dma_chan struct) in
this '32' case right here (line ~735):
> hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE;
Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes
the NULL'd hsdevp->chan to the dmaengine_slave_config() which then
causes the crash.
With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1.
This avoids the OOB. But please note, there was a worthwhile discussion
on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not
be a "fake" 33 command-long queue size.
Ideally, the dw driver should account for the ATA_TAG_INTERNAL.
In Damien Le Moal's words: "... having looked at the driver, it
is a bigger change than just faking a 33rd "tag" that is in fact
not a command tag at all."

The driver creates the mapping by calling irq_of_parse_and_map(),
so it also has to dispose the mapping. But the easy way out is to
simply use platform_get_irq() instead of irq_of_parse_map(). Also
we should adapt return value checking and propagate error values.
In this case the mapping is not managed by the device but by
the of core, so the device has not to dispose the mapping.

For AMD's Renoir and Green Sardine platforms it's important that any

If the disk is left in active/partial/slumber, then the system is not able
to resume properly.
When the StorageD3Enable _DSD is detected, check the system is using s2idle
and DevSlp is enabled and if so explicitly wait long enough for the disk to

commit f971a85439bd25dc7b4d597cf5e4e8dc7ffc884b upstream.
Checking if DMA is enabled should be done via the
ata_dma_enabled helper function, since the init state
0xff indicates disabled.
This meant that ATA_CMD_READ_LOG_DMA_EXT was used and probed
for before DMA was enabled, which caused hangs for some combinations
of controllers and devices.
It might also have caused it to be incorrectly disabled as broken,
but there have been no reports of that.

commit 68dbbe7d5b4fde736d104cbbc9a2fce875562012 upstream.
Some ATA drives are very slow to respond to READ_LOG_EXT and
READ_LOG_DMA_EXT commands issued from ata_dev_configure() when the
device is revalidated right after resuming a system or inserting the
ATA adapter driver (e.g. ahci). The default 5s timeout
(ATA_EH_CMD_DFL_TIMEOUT) used for these commands is too short, causing
errors during the device configuration. Ex:
...
ata9: SATA max UDMA/133 abar m524288@0x9d200000 port 0x9d200400 irq 209
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: ATA-9: XXX XXXXXXXXXXXXXXX, XXXXXXXX, max UDMA/133
ata9.00: qc timeout (cmd 0x2f)
ata9.00: Read log page 0x00 failed, Emask 0x4
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: NCQ Send/Recv Log not supported
ata9.00: Read log page 0x08 failed, Emask 0x40
ata9.00: 27344764928 sectors, multi 16: LBA48 NCQ (depth 32), AA
ata9.00: Read log page 0x00 failed, Emask 0x40
ata9.00: ATA Identify Device Log not supported
ata9.00: failed to set xfermode (err_mask=0x40)
ata9: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata9.00: configured for UDMA/133
...
The timeout error causes a soft reset of the drive link, followed in
most cases by a successful revalidation as that give enough time to the
drive to become fully ready to quickly process the read log commands.
However, in some cases, this also fails resulting in the device being
dropped.
Fix this by using adding the ata_eh_revalidate_timeouts entries for the
READ_LOG_EXT and READ_LOG_DMA_EXT commands. This defines a timeout
increased to 15s, retriable one time.

mv_init_host() propagates the value returned by mv_chip_id() which in turn
gets propagated by mv_pci_init_one() and hits local_pci_probe().
During the process of driver probing, the probe function should return < 0
for failure, otherwise, the kernel will treat value > 0 as success.
Since this is a bug rather than a recoverable runtime error we should
use dev_alert() instead of dev_err().

Many users are reporting that the Samsung 860 and 870 SSD are having
various issues when combined with AMD/ATI (vendor ID 0x1002) SATA
controllers and only completely disabling NCQ helps to avoid these
issues.
Always disabling NCQ for Samsung 860/870 SSDs regardless of the host
SATA adapter vendor will cause I/O performance degradation with well
behaved adapters. To limit the performance impact to ATI adapters,
introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ
only for these adapters.
Also, two libata.force parameters (noncqati and ncqati) are introduced
to disable and enable the NCQ for the system which equipped with ATI
SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ
function to be enabled or disabled according to the demand.
After verifying the chipset from the user reports, the issue appears
on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on
recent AMD SATA adapters. The vendor ID of ATI should be 0x1002.
Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to
ATA_HORKAGE_NO_NCQ_ON_ATI.

Commit ca6bfcb2f6d9 ("libata: Enable queued TRIM for Samsung SSD 860")
limited the existing ATA_HORKAGE_NO_NCQ_TRIM quirk from "Samsung SSD 8*",
covering all Samsung 800 series SSDs, to only apply to "Samsung SSD 840*"
and "Samsung SSD 850*" series based on information from Samsung.
But there is a large number of users which is still reporting issues
with the Samsung 860 and 870 SSDs combined with Intel, ASmedia or
Marvell SATA controllers and all reporters also report these problems
going away when disabling queued trims.
Note that with AMD SATA controllers users are reporting even worse
issues and only completely disabling NCQ helps there, this will be
addressed in a separate patch.

Currently, the only way a user can determine if a SATA device supports
NCQ priority is to try to enable the use of this feature using the
ncq_prio_enable sysfs device attribute. If enabling the feature fails,
it is because the device does not support NCQ priority. Otherwise, the
feature is enabled and success indicates that the device supports NCQ
priority.
Improve this odd interface by introducing the read-only
ncq_prio_supported sysfs device attribute to indicate if a SATA device
supports NCQ priority. The value of this attribute reflects the status
of device flag ATA_DFLAG_NCQ_PRIO, which is set only for devices
supporting NCQ priority.
Add this new sysfs attribute to the device attributes group of libahci
and libata-sata.

Support for the READ LOG PAGE DMA EXT command is indicated by words 119
and 120 of a device identify data. This is tested in
ata_read_log_page() with ata_id_has_read_log_dma_ext() and the
READ LOG PAGE DMA command used if the device reports supports for it.
However, some devices lie about this support and using the DMA version
of the command fails, generating the warning message "READ LOG DMA EXT
failed, trying PIO". Since READ LOG PAGE DMA EXT is an optional command,
this warning is not at all important but may be scary for the user.
Change ata_read_log_page() to suppres this warning and to print an
error message if both DMA and PIO attempts failed.
With this change, there is no need to print again an error message when
ata_read_log_page() returns an error. So simplify the users of this
function.

The ata device flag ATA_DFLAG_NCQ_PRIO indicates if a device supports
the NCQ Priority feature while the ATA_DFLAG_NCQ_PRIO_ENABLE device
flag indicates if the feature is enabled. Enabling NCQ priority use is
controlled by the user through the device sysfs attribute
ncq_prio_enable. As a result, the ATA_DFLAG_NCQ_PRIO flag should not be
cleared when ATA_DFLAG_NCQ_PRIO_ENABLE is not set as the device still
supports the feature even after the user disables it. This leads to the
following cleanups:
- In ata_build_rw_tf(), set a command high priority bit based on the
ATA_DFLAG_NCQ_PRIO_ENABLE flag, not on the ATA_DFLAG_NCQ flag. That
is, set a command high priority only if the user enabled NCQ priority
use.
- In ata_dev_config_ncq_prio(), ATA_DFLAG_NCQ_PRIO should not be cleared
if ATA_DFLAG_NCQ_PRIO_ENABLE is not set. If the device does not
support NCQ priority, both ATA_DFLAG_NCQ_PRIO and
ATA_DFLAG_NCQ_PRIO_ENABLE must be cleared.
With the above ata_dev_config_ncq_prio() change, ATA_DFLAG_NCQ_PRIO flag
is set on device scan and revalidation. There is no need to trigger a
device revalidation in ata_ncq_prio_enable_store() when the user enables
the use of NCQ priority. Remove the revalidation code from that funciton
to simplify it. Also change the return value from -EIO to -EINVAL when a
user tries to enable NCQ priority for a device that does not support
this feature. While at it, also simplify ata_ncq_prio_enable_show().
Overall, there is no functional change introduced by this patch.

- Add a new expansion bus driver.
- Rewrite the watchdog driver to use the watchdog core and
spawn from the timer (clocksource) driver.
- Refactor the PATA/libata driver to probe from the device
tree and use the expansion bus driver to manipulate chip
select timings directly.

This rewrites the IXP4xx CF (IDE) libata driver to use the
device tree exclusively to look up its resources:
- Probe exclusively from the device tree and look up all
resources from there.
- Allocate a local state container with devres and pass
this around in .private_data.
- Initialize with struct ata_port_info.
- Use the .set_piomode() callback instead of the much
wider .set_mode(), we only support PIO after all.
- Bump driver version number from 0.2 to 1.0 to reflect this
wider change.
- Get a handle on the expansion bus syscon regmap to alter
the timings on the chip select.
- Put in the more elaborate timing adjustment code for PIO0
to PIO4 in 8 and 16bit mode from the downstream OpenWrt
patch.
The board file initialization path and platform data include
is dropped because the board files will be deleted at the same
time as this patch is merged.
The platform data file is not deleted right now so as not to
conflict with the removal of board files.

The two "cs0" and "cs1" are "chip selects" but on some
platforms such as GW2358 they are actually both in CS3
making this terminology very confusing. Call the
addresses "cmd" and "ctl" after function instead.

Pull libata fixlets from Jens Axboe:
- A fix for PIO highmem (Christoph)
- Kill HAVE_IDE as it's now unused (Lukas)
* tag 'libata-5.14-2021-07-30' of git://git.kernel.dk/linux-block:
arch: Kconfig: clean up obsolete use of HAVE_IDE
libata: fix ata_pio_sector for CONFIG_HIGHMEM
Last change to device managed APIs cleaned up error path to simple phy_exit()
call, which in some cases has been executed with NULL parameter. This per se
is not a problem, but rather logical misconception: no need to free resource
when it's for sure has not been allocated yet. Fix the driver accordingly.

A few SoC (code) changes have queued up this cycle, mostly for minor
changes and some refactoring and cleanup of legacy platforms. This
branch also contains a few of the fixes that weren't sent in by the end
of the release (all fairly minor).
- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing legacy
mach/* include dependencies and moving platform detection/config to
drivers/soc. Also some updates/cleanup of platform data.
- Core power domain support for Tegra platforms, and some improvements
in build test coverage by adding stubs for compile test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP
support on i.MX7D, SoC ID setup for i.MX50, removal of platform data
and board fixups for iMX6/7.
... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
Rockchip.
