Linus Torvalds fe91c4725a SCSI misc on 20211105
This series consists of the usual driver updates (ufs, smartpqi, lpfc,
 target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
 fixes.  Notable core changes are the removal of scsi->tag which caused
 some churn in obsolete drivers and a sweep through all drivers to call
 scsi_done() directly instead of scsi->done() which removes a pointer
 indirection from the hot path and a move to register core sysfs files
 earlier, which means they're available to KOBJ_ADD processing, which
 necessitates switching all drivers to using attribute groups.

Add support to discover if an ATA device supports the Concurrent
Positioning Ranges data log (address 0x47), indicating that the device
is capable of seeking to multiple different locations in parallel using
multiple actuators serving different LBA ranges.

Also add support to translate the concurrent positioning ranges log
into its equivalent Concurrent Positioning Ranges VPD page B9h in
libata-scsi.c.

The format of the Concurrent Positioning Ranges Log is defined in ACS-5
r9.

Zheyu Ma a0023bb9dd ata: sata_mv: Fix the error handling of mv_chip_id()
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().

commit 962399bb7f ("ata: libahci_platform: Fix regulator_get_optional()

Reimar Döffinger f971a85439 libata: fix checking of DMA state
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.

Kate Hsuan 7a8526a5cd libata: Add ATA_HORKAGE_NO_NCQ_ON_ATI for Samsung 860 and 870 SSD.
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.

Hans de Goede 8a6430ab9c libata: add ATA_HORKAGE_NO_NCQ_TRIM for Samsung 860 and 870 SSDs
Commit ca6bfcb2f6 ("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.

Damien Le Moal 5f91b8f548 libata: Introduce ncq_prio_supported sysfs sttribute
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.

Damien Le Moal fc5c8aa7bc libata: fix ata_read_log_page() warning
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.

Damien Le Moal 2360fa1812 libata: cleanup NCQ priority handling
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.

Linus Walleij 47adef20e6 pata: ixp4xx: Rewrite to use device tree
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.

Merge tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC updates from Olof Johansson:
 "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"

Christoph Hellwig ecef6a9eff libata: fix ata_pio_sector for CONFIG_HIGHMEM
Data transfers are not required to be block aligned in memory, so they
span two pages.  Fix this by splitting the call to >sff_data_xfer into
two for that case.

This has been broken since the initial libata import before the damn
of git, but was uncovered by the legacy ide driver removal.

Linus Walleij d5d9f7ac58 ARM/ixp4xx: Make NEED_MACH_IO_H optional
In order to create a proper PCI driver for the IXP4xx
we need to make the old PCI driver and its reliance
on <mach/io.h> optional.

Create a new Kconfig symbol for the legacy PCI driver
IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H
for this driver.

A few files need to be adjusted to explicitly include
the <mach/hardware.h> and <mach/cpu.h> headers that
they previously obtained implicitly using <linux/io.h>
that would include <mach/io.h> and in turn include
these two headers.

This breaks our reliance on the old PCI and indirect
PCI support so we can reimplement a proper purely
DT-based driver in the PCI subsystem.

Timo Sigurdsson f6bca4d91b ata: ahci_sunxi: Disable DIPM
DIPM is unsupported or broken on sunxi. Trying to enable the power
management policy med_power_with_dipm on an Allwinner A20 SoC based board
leads to immediate I/O errors and the attached SATA disk disappears from
the /dev filesystem. A reset (power cycle) is required to make the SATA
controller or disk work again. The A10 and A20 SoC data sheets and manuals
don't mention DIPM at all [1], so it's fair to assume that it's simply not
supported. But even if it was, it should be considered broken and best be
disabled in the ahci_sunxi driver.

Finn Thain 44b1fbc0f5 m68k/q40: Replace q40ide driver with pata_falcon and falconide
This allows m68k q40 systems to switch from the deprecated IDE subsystem
to libata.

Enhance the byte-swapping falconide and pata_falcon platform drivers to
accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem
to co-exist with q40 IRQ arrangements without too much mess.

The new IO resources were added solely for the purpose of making
request_region() reservations identical to those made by q40ide: these
regions aren't used for actual IO.

Hannes Reinecke 3d45cefc8e scsi: core: Drop obsolete Linux-specific SCSI status codes
Originally the SCSI subsystem has been using 'special' SCSI status codes,
which were the SAM-specified ones but shifted by 1.  As most drivers have
now been modified to use the SAM-specified ones, having two nearly
identical sets of definitions only causes confusion.

The Linux-specifed SCSI status codes have been marked obsolete for several
years so drop them and use the SAM-specified status codes throughout.

Hannes Reinecke 464a00c9e0 scsi: core: Kill DRIVER_SENSE
Replace the check for DRIVER_SENSE with a check for
scsi_status_is_check_condition().

Audit all callsites to ensure the SAM status is set correctly. For
backwards compability move the DRIVER_SENSE definition to sg.h, and update
sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever
SAM_STAT_CHECK_CONDITION is present.

Sergey Shtylyov bfc1f378c8 pata_octeon_cf: avoid WARN_ON() in ata_host_activate()
Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode
has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler'
parameter being non-NULL if the polling mode is selected.  Let's only set
the pointer to the driver's IRQ handler if platform_get_irq() returns a
valid IRQ # -- this should avoid the unnecessary WARN_ON()...

Bart Van Assche b8e162f9e7 scsi: core: Introduce enum scsi_disposition
Improve readability of the code in the SCSI core by introducing an
enumeration type for the values used internally that decide how to continue
processing a SCSI command. The eh_*_handler return values have not been
changed because that would involve modifying all SCSI drivers.

The output of the following command has been inspected to verify that no
out-of-range values are assigned to a variable of type enum
scsi_disposition:

KCFLAGS=-Wassign-enum make CC=clang W=1 drivers/scsi/

int variable 'irq', so making 'irq' an int, and change the position to

Sowjanya Komatineni 868ed7311c ata: ahci_tegra: Add AHCI support for Tegra186
This patch adds support for AHCI-compliant Serial ATA controller
on Tegra186 SoC.

Tegra186 does not have sata-oob reset.
Tegra186 SATA_NVOOB register filed COMMA_CNT position and width are
different compared to Tegra210 and prior.

So, this patch adds a flag has_sata_oob_rst and tegra_ahci_regs to
SoC specific strcuture tegra_ahci_soc and updated their implementation
accordingly.

Maciej W. Rozycki 7d33004d24 pata_legacy: Add `probe_mask' parameter like with ide-generic
Carry the `probe_mask' parameter over from ide-generic to pata_legacy so
that there is a way to prevent random poking at ISA port I/O locations
in attempt to discover adapter option cards with libata like with the
old IDE driver.  By default all enabled locations are tried, however it
may interfere with a different kind of hardware responding there.

For example with a plain (E)ISA system the driver tries all the six
possible locations:

scsi host0: pata_legacy
ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14
ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100

scsi host1: pata_legacy
ata6: PATA max PIO4 cmd 0x160 ctl 0x366 irq 12

however giving the kernel "pata_legacy.probe_mask=21" makes it try every
other location only:

Add the missing documentation pieces then and reorder parameters into a

- `all' affects primary and secondary port ranges only rather than all,

- `probe_all' affects tertiary and further port ranges rather than all,

- `ht6560b' is for HT 6560B rather than HT 6560A.

Sergey Shtylyov e379b40cc0 pata_ipx4xx_cf: fix IRQ check
The driver's probe() method is written as if platform_get_irq() returns 0
on error, while actually it returns a negative error code (with all the
other values considered valid IRQs).  Rewrite the driver's IRQ checking
code to pass the positive IRQ #s to ata_host_activate(), propagate errors
upstream, and treat IRQ0 as error, returning -EINVAL, as the libata code
treats 0  as  an indication that polling should be used anyway...

Piyush Mehta 9a9d3abe24 ata: ahci: ceva: Update the driver to support xilinx GT phy
SATA controller used in Xilinx ZynqMP platform uses xilinx GT phy
which has 4 GT lanes and can be used by 4 peripherals at a time.
SATA controller uses 1 GT phy lane among the 4 GT lanes. To configure
the GT lane for the SATA controller, the below sequence is expected.

1. Assert the SATA controller reset.
2. Configure the xilinx GT phy lane for SATA controller (phy_init).
3. De-assert the SATA controller reset.
4. Wait for PLL of the GT lane used by SATA to be locked (phy_power_on).

The ahci_platform_enable_resources() by default does the phy_init()
and phy_power_on() but the default sequence doesn't work with Xilinx
platforms. Because of this reason, updated the driver to support the
new sequence.

Added cevapriv->rst check, for backward compatibility with the older
sequence. If the reset controller is not available, then the SATA
controller will configure with the older sequences.

Geert Uytterhoeven df9c590986 ata: sata_rcar: Fix DMA boundary mask
Before commit 9495b7e92f ("driver core: platform: Initialize
dma_parms for platform devices"), the R-Car SATA device didn't have DMA
parameters.  Hence the DMA boundary mask supplied by its driver was
silently ignored, as __scsi_init_queue() doesn't check the return value
of dma_set_seg_boundary(), and the default value of 0xffffffff was used.

Now the device has gained DMA parameters, the driver-supplied value is
used, and the following warning is printed on Salvator-XS:

    DMA-API: sata_rcar ee300000.sata: mapping sg segment across boundary [start=0x00000000ffffe000] [end=0x00000000ffffefff] [boundary=0x000000001ffffffe]
    WARNING: CPU: 5 PID: 38 at kernel/dma/debug.c:1233 debug_dma_map_sg+0x298/0x300

(the range of start/end values depend on whether IOMMU support is
 enabled or not)

The issue here is that SATA_RCAR_DMA_BOUNDARY doesn't have bit 0 set, so
any typical end value, which is odd, will trigger the check.

Fix this by increasing the DMA boundary value by 1.

This also fixes the following WRITE DMA EXT timeout issue:

    # dd if=/dev/urandom of=/mnt/de1/file1-1024M bs=1M count=1024
    ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen

Pali Rohár 45aefe3d22 ata: ahci: mvebu: Make SATA PHY optional for Armada 3720
Older ATF does not provide SMC call for SATA phy power on functionality and
therefore initialization of ahci_mvebu is failing when older version of ATF
is using. In this case phy_power_on() function returns -EOPNOTSUPP.

This patch adds a new hflag AHCI_HFLAG_IGN_NOTSUPP_POWER_ON which cause
that ahci_platform_enable_phys() would ignore -EOPNOTSUPP errors from
phy_power_on() call.

It fixes initialization of ahci_mvebu on Espressobin boards where is older
Marvell's Arm Trusted Firmware without SMC call for SATA phy power.

This is regression introduced in commit 8e18c8e58d ("arm64: dts: marvell:
armada-3720-espressobin: declare SATA PHY property") where SATA phy was
defined and therefore ahci_platform_enable_phys() on Espressobin started
failing.

All three generations of Sandisk SSDs lock up hard intermittently.
Experiments showed that disabling NCQ lowered the failure rate significantly
and the kernel has been disabling NCQ for some models of SD7's and 8's,
which is obviously undesirable.

Karthik worked with Sandisk to root cause the hard lockups to trim commands
larger than 128M. This patch implements ATA_HORKAGE_MAX_TRIM_128M which
limits max trim size to 128M and applies it to all three generations of
Sandisk SSDs.

Kees Cook 3f649ab728 treewide: Remove uninitialized_var() usage
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.

Kai-Heng Feng b5292111de libata: Use per port sync for detach
Commit 130f4caf14 ("libata: Ensure ata_port probe has completed before
detach") may cause system freeze during suspend.

Using async_synchronize_full() in PM callbacks is wrong, since async
callbacks that are already scheduled may wait for not-yet-scheduled
callbacks, causes a circular dependency.

Instead of using big hammer like async_synchronize_full(), use async
cookie to make sure port probe are synced, without affecting other
scheduled PM callbacks.

You can refer to "https://www.lkml.org/lkml/2019/1/17/474" reproduce
this error.

The exception code is "bd_len = p[3];", "p" value is ffff88803b8cd000
which belongs to the cache kmalloc-512 of size 512. The "page_address(sg_page(scsi_sglist(scmd)))"
maybe from sg_scsi_ioctl function "buffer" which allocated by kzalloc, so "buffer"
may not page aligned.
This also looks completely buggy on highmem systems and really needs to use a
kmap_atomic.      --Christoph Hellwig
To address above bugs, Paolo Bonzini advise to simpler to just make a char array
of size CACHE_MPAGE_LEN+8+8+4-2(or just 64 to make it easy), use sg_copy_to_buffer
to copy from the sglist into the buffer, and workthere.

Linus Torvalds b23c4771ff A fair amount of stuff this time around, dominated by yet another massive
set from Mauro toward the completion of the RST conversion.  I *really*
 hope we are getting close to the end of this.  Meanwhile, those patches
 reach pretty far afield to update document references around the tree;
 there should be no actual code changes there.  There will be, alas, more of
 the usual trivial merge conflicts.
 
 Beyond that we have more translations, improvements to the sphinx
 scripting, a number of additions to the sysctl documentation, and lots of

Don't burden the common block code with with specifics of the libata DMA
draining mechanism.  Instead move most of the code to the scsi midlayer.

That also means the nr_phys_segments adjustments in the blk-mq fast path
can go away entirely, given that SCSI never looks at nr_phys_segments
after mapping the request to a scatterlist.

* remove dev_attr_ncq_prio_enable from ata_common_sdev_attrs[]

* add ata_ncq_sdev_attrs[]

* update ATA_NCQ_SHT() macro to use ata_ncq_sdev_attrs[]

Linus Walleij 45b8084f3f libata: Assign OF node to the SCSI device
When we spawn a SCSI device from an ATA device in libata-scsi
the SCSI device had no relation to the device tree.

The DT binding allows us to define port nodes under a
PATA (IDE) or SATA host controller, so we can have proper device
nodes for these devices.

If OF is enabled, walk the children of the host controller node
to see if there is a valid device tree node to assign. The reg
is used to match to ID 0 for the master device and ID 1 for the
slave device.

The corresponding device tree bindings have been accepted by
the device tree maintainers.

There is also refcount issue, as well:
WARNING: CPU: 1 PID: 1 at lib/refcount.c:28 refcount_warn_saturate+0xf8/0x170

The issue is that we make an erroneous extra call to scsi_host_put()
for that host:

So in ahci_init_one()->ata_host_alloc_pinfo()->ata_host_alloc(), we setup
a device release method - ata_devres_release() - which intends to release
the SCSI hosts:

static void ata_devres_release(struct device *gendev, void *res)
{
	...
	for (i = 0; i < host->n_ports; i++) {
		struct ata_port *ap = host->ports[i];

		if (!ap)
			continue;

		if (ap->scsi_host)
			scsi_host_put(ap->scsi_host);

	}
	...
}

However in the ata_scsi_add_hosts() error path, we also call
scsi_host_put() for the SCSI hosts.

Fix by removing the the scsi_host_put() calls in ata_scsi_add_hosts() and
leave this to ata_devres_release().

for SCSI devices, it is used by all libata drivers as well as a few
drivers that support SAS attached SATA drives.

The only command that is not safe for compat ioctls here is
HDIO_GET_32BIT. Change the implementation to check for in_compat_syscall()
in order to do both cases correctly, and change all callers to use it
as both native and compat callback pointers, including the indirect
callers through sas_ioctl and ata_scsi_ioctl.

Florian Fainelli 3c696ac417 ata: ahci_brcm: Manage reset line during suspend/resume
We were not managing the reset line during suspend/resume, but this
needs to be done to ensure that the controller can exit low power modes
correctly, especially with deep sleep suspend mode that may reset parts
of the logic.

Florian Fainelli bf0e5013bc ata: ahci_brcm: Add missing clock management during recovery
The downstream implementation of ahci_brcm.c did contain clock
management recovery, but until recently, did that outside of the
libahci_platform helpers and this was unintentionally stripped out while
forward porting the patch upstream.

Add the missing clock management during recovery and sleep for 10
milliseconds per the design team recommendations to ensure the SATA PHY
controller and AFE have been fully quiesced.

Florian Fainelli 1a3d78cb6e ata: ahci_brcm: BCM7425 AHCI requires AHCI_HFLAG_DELAY_ENGINE
Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making
it conforming to the 'strict' AHCI implementation which this controller
is based on.

This solves long link establishment with specific hard drives (e.g.:
Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the
error recovery handling before finally establishing a succesful SATA
link at the desired speed.

We re-order the hpriv->flags assignment to also remove the NONCQ quirk
since we can set the flag directly.

Florian Fainelli c0cdf2ac4b ata: ahci_brcm: Fix AHCI resources management
The AHCI resources management within ahci_brcm.c is a little
convoluted, largely because it historically had a dedicated clock that
was managed within this file in the downstream tree. Once brough
upstream though, the clock was left to be managed by libahci_platform.c
which is entirely appropriate.

This patch series ensures that the AHCI resources are fetched and
enabled before any register access is done, thus avoiding bus errors on
platforms which clock gate the controller by default.

As a result we need to re-arrange the suspend() and resume() functions
in order to avoid accessing registers after the clocks have been turned
off respectively before the clocks have been turned on. Finally, we can
refactor brcm_ahci_get_portmask() in order to fetch the number of ports
from hpriv->mmio which is now accessible without jumping through hoops
like we used to do.

The commit pointed in the Fixes tag is both old and new enough not to
require major headaches for backporting of this patch.

Sascha Hauer 8385d756e1 libata: Fix retrieving of active qcs
ata_qc_complete_multiple() is called with a mask of the still active
tags.

mv_sata doesn't have this information directly and instead calculates
the still active tags from the started tags (ap->qc_active) and the
finished tags as (ap->qc_active ^ done_mask)

Since 28361c4036 the hw_tag and tag are no longer the same and the
equation is no longer valid. In ata_exec_internal_sg() ap->qc_active is
initialized as 1ULL << ATA_TAG_INTERNAL, but in hardware tag 0 is
started and this will be in done_mask on completion. ap->qc_active ^
done_mask becomes 0x100000000 ^ 0x1 = 0x100000001 and thus tag 0 used as
the internal tag will never be reported as completed.

This is fixed by introducing ata_qc_get_active() which returns the
active hardware tags and calling it where appropriate.

This is tested on mv_sata, but sata_fsl and sata_nv suffer from the same
problem. There is another case in sata_nv that most likely needs fixing
as well, but this looks a little different, so I wasn't confident enough
to change that.

Linus Torvalds 99a0d9f5e8 This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
 
 - Expose pull up/down flags for the GPIO character device to
   userspace. After clear input from the RaspberryPi and Beagle
   communities, it has been established that prototyping,
   industrial automation and make communities strongly need
   this feature, and as we want people to use the character
   device, we have implemented the simple pull up/down
   interface for GPIO lines. This means we can specify that
   a (chip-specific) pull up/down resistor can be enabled,
   but does not offer fine-grained control such as cases
   where the resistance of the same pull resistor can be
   controlled (yet).
 
 - Introduce devm_fwnode_gpiod_get_index() and start to phase out
   the old symbol devm_fwnode_get_index_gpiod_from_child().
 
 - A bit of documentation clean-up work.
 
 - Introduce a define for GPIO line directions and deploy it
   in all GPIO drivers in the drivers/gpio directory.
 
 - Add a special callback to populate pin ranges when
   cooperating with the pin control subsystem and registering
   ranges as part of adding a gpiolib driver and a
   gpio_irq_chip driver at the same time. This is also
   deployed in the Intel Merrifield driver.
 
 New drivers:
 
 - RDA Micro GPIO controller.
 
 - XGS-iproc GPIO driver.
 
 Driver improvements:
 
 - Wake event and debounce support on the Tegra 186 driver.
 
 - Finalize the Aspeed SGPIO driver.
 
 - MPC8xxx uses a normal IRQ handler rather than a chained
   handler.

Merge tag 'gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.5 kernel cycle

  Core changes:

   - Expose pull up/down flags for the GPIO character device to
     userspace.

     After clear input from the RaspberryPi and Beagle communities, it
     has been established that prototyping, industrial automation and
     make communities strongly need this feature, and as we want people
     to use the character device, we have implemented the simple pull
     up/down interface for GPIO lines.

     This means we can specify that a (chip-specific) pull up/down
     resistor can be enabled, but does not offer fine-grained control
     such as cases where the resistance of the same pull resistor can be
     controlled (yet).

   - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
     old symbol devm_fwnode_get_index_gpiod_from_child().

   - A bit of documentation clean-up work.

   - Introduce a define for GPIO line directions and deploy it in all
     GPIO drivers in the drivers/gpio directory.

   - Add a special callback to populate pin ranges when cooperating with
     the pin control subsystem and registering ranges as part of adding
     a gpiolib driver and a gpio_irq_chip driver at the same time. This
     is also deployed in the Intel Merrifield driver.

  New drivers:

   - RDA Micro GPIO controller.

   - XGS-iproc GPIO driver.

  Driver improvements:

   - Wake event and debounce support on the Tegra 186 driver.

   - Finalize the Aspeed SGPIO driver.

   - MPC8xxx uses a normal IRQ handler rather than a chained handler"

Nicolas Saenz Julienne a7ba70f178 dma-mapping: treat dev->bus_dma_mask as a DMA limit
Using a mask to represent bus DMA constraints has a set of limitations.
The biggest one being it can only hold a power of two (minus one). The
DMA mapping code is already aware of this and treats dev->bus_dma_mask
as a limit. This quirk is already used by some architectures although
still rare.

With the introduction of the Raspberry Pi 4 we've found a new contender
for the use of bus DMA limits, as its PCIe bus can only address the
lower 3GB of memory (of a total of 4GB). This is impossible to represent
with a mask. To make things worse the device-tree code rounds non power
of two bus DMA limits to the next power of two, which is unacceptable in
this case.

In the light of this, rename dev->bus_dma_mask to dev->bus_dma_limit all
over the tree and treat it as such. Note that dev->bus_dma_limit should
contain the higher accessible DMA address.

Michael Schmitz 5ed0794cde m68k/atari: Convert Falcon IDE drivers to platform drivers
Autoloading of Falcon IDE driver modules requires converting these
drivers to platform drivers.

Add platform device for Falcon IDE interface in Atari platform setup
code. Use this in the pata_falcon driver in place of the simple
platform device set up on the fly.

Convert falconide driver to use the same platform device that is used
by pata_falcon also. (With the introduction of a platform device for
the Atari Falcon IDE interface, the old Falcon IDE driver no longer
loads (resource already claimed by the platform device)).

Tested (as built-in driver) on my Atari Falcon.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1652185
https://bugs.centos.org/view.php?id=14998

Let sata_mv handle the failure gracefully: warn about that incl. the

now thanks to the previous patch.

Remove also the long-standing FIXME.

With KASAN also enabled, we may also get many use-after-free reports.

The issue is that when CONFIG_DEBUG_TEST_DRIVER_REMOVE is set, we may
attempt to detach the ata_port before it has been probed.

This is because the ata_ports are async probed, meaning that there is no
guarantee that the ata_port has probed prior to detach. When the ata_port
does probe in this scenario, we get all sorts of issues as the detach may
have already happened.

Fix by ensuring synchronisation with async_synchronize_full(). We could
alternatively use the cookie returned from the ata_port probe
async_schedule() call, but that means managing the cookie, so more
complicated.

Mark Brown 962399bb7f ata: libahci_platform: Fix regulator_get_optional() misuse
This driver is using regulator_get_optional() to handle all the supplies
that it handles, and only ever enables and disables all supplies en masse
without ever doing any other configuration of the device to handle missing
power. These are clear signs that the API is being misused - it should only
be used for supplies that may be physically absent from the system and in
these cases the hardware usually needs different configuration if the
supply is missing. Instead use normal regualtor_get(), if the supply is
not described in DT then the framework will substitute a dummy regulator in
so no special handling is needed by the consumer driver.

In the case of the PHY regulator the handling in the driver is a hack to
deal with integrated PHYs; the supplies are only optional in the sense
that that there's some confusion in the code about where they're bound to.
From a code point of view they function exactly as normal supplies so can
be treated as such. It'd probably be better to model this by instantiating
a PHY object for integrated PHYs.

Linus Walleij 8a99358a1d ata: ahci-imx: Covert to use GPIO descriptor
This converts the i.MX AHCI driver to use a GPIO descriptor
instead of parsing the device tree by itself.

This driver is quite obviously device tree only, and the
GPIO line is treated as optional, so let's keep it as
optional.

None of the device trees in the kernel use this GPIO
facility today, so it is hard to test.

Dan Williams 09d6ac8dc5 libata/ahci: Fix PCS quirk application
Commit c312ef1763 "libata/ahci: Drop PCS quirk for Denverton and
beyond" got the polarity wrong on the check for which board-ids should
have the quirk applied. The board type board_ahci_pcs7 is defined at the
end of the list such that "pcs7" boards can be special cased in the
future if they need the quirk. All prior Intel board ids "<
board_ahci_pcs7" should proceed with applying the quirk.

PCI_STD_RESOURCE_END.  However, that requires the unusual test
"i <= PCI_STD_RESOURCE_END" rather than something the typical
"i < PCI_STD_NUM_BARS".

Add a definition for PCI_STD_NUM_BARS and change loops to use the more
idiomatic C style to help avoid fencepost errors.

Dan Williams c312ef1763 libata/ahci: Drop PCS quirk for Denverton and beyond
The Linux ahci driver has historically implemented a configuration fixup
for platforms / platform-firmware that fails to enable the ports prior
to OS hand-off at boot. The fixup was originally implemented way back
before ahci moved from drivers/scsi/ to drivers/ata/, and was updated in
2007 via commit 49f2909039 "ahci: update PCS programming". The quirk
sets a port-enable bitmap in the PCS register at offset 0x92.

This quirk could be applied generically up until the arrival of the
Denverton (DNV) platform. The DNV AHCI controller architecture supports
more than 6 ports and along with that the PCS register location and
format were updated to allow for more possible ports in the bitmap. DNV
AHCI expands the register to 32-bits and moves it to offset 0x94.

As it stands there are no known problem reports with existing Linux
trying to set bits at offset 0x92 which indicates that the quirk is not
applicable. Likely it is not applicable on a wider range of platforms,
but it is difficult to discern which platforms if any still depend on
the quirk.

Rather than try to fix the PCS quirk to consider the DNV register layout
instead require explicit opt-in. The assumption is that the OS driver
need not touch this register, and platforms can be added with a new
boad_ahci_pcs7 board-id when / if problematic platforms are found in the
future. The logic in ahci_intel_pcs_quirk() looks for all Intel AHCI
instances with "legacy" board-ids and otherwise skips the quirk if the
board was matched by class-code.
