99ad3f9f82 ata: libata-core: improve parameter names for ata_dev_set_feature()
ata_dev_set_feature() is currently used for enabling/disabling any ATA
feature, e.g. SETFEATURES_SPINUP and SETFEATURE_SENSE_DATA, i.e. it is
not only used to enable/disable SATA specific features.

For most features, the enable/disable bit is specified in the subcommand
specific field "count".
It is only for the specific subcommands "Enable SATA feature" (0x10) and
"Disable SATA feature" (0x90) where the field "count" is used to specify
a feature instead of enable/disable. The parameter names for this
function are thus quite misleading.

Rename the parameter names to be more generic and in line with ACS-5,
and remove the references to "SATA FEATURES" in the kernel-doc.

f1d8b5042e ata/drivers/ahci_imx: Switch to new of thermal API
The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.

Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

sata_ahci_read_temperature() is used by sata_ahci_show_temp() also.

So in order to change the function prototype for the get_temp ops which
does not take a void* but a thermal_zone_device* structure, this
function wraps the call.

b3b2bec964 ata: sata_mv: Fixes expected number of resources now IRQs are gone
The commit a1a2b7125e ("of/platform: Drop static setup of IRQ
resource from DT core") stopped IRQ resources being available as
platform resources. This broke the sanity check for the expected
number of resources in the Marvell SATA driver which expected two
resources, the IO memory and the interrupt.

Change the sanity check to only expect the IO memory.

0568e61225 ata: libata-scsi: cap ata_device->max_sectors according to shost->max_sectors
ATA devices (struct ata_device) have a max_sectors field which is
configured internally in libata. This is then used to (re)configure the
associated sdev request queue max_sectors value from how it is earlier set
in __scsi_init_queue(). In __scsi_init_queue() the max_sectors value is set
according to shost limits, which includes host DMA mapping limits.

Cap the ata_device max_sectors according to shost->max_sectors to respect
this shost limit.

0184898dd1 ata: libata-scsi: fix result type of ata_ioc32()
While ata_ioc32() returns 'int', its result gets assigned to and compared
with the 'unsigned long' variable 'val' in ata_sas_scsi_ioctl(), its only
caller, which implies a problematic implicit cast (with sign extension).
Fix this by returning 'bool' instead -- the implicit cast then implies
zero extension which is OK.  Note that actually the object code doesn't
change because ata_ioc32() is always inlined -- I can see the expected
code changes with 'noinline'...

The packed transfer mode masks and also the {pio|mwdma|udma}_mask fields
of *struct*s ata_device and ata_port_info are declared as *unsigned long*
(which is a 64-bit type on 64-bit architectures) but actually the packed
masks occupy only 20 bits (7 PIO modes, 5 MWDMA modes, and 8 UDMA modes)
and the PIO/MWDMA/UDMA masks easily fit into just 8 bits each, so we can
safely use (always 32-bit) *unsigned int* variables instead.  This saves
745 bytes of object code in libata-core.o alone, not to mention LLDDs...

72aad489f9 ata: libata-transport: fix {dma|pio|xfer}_mode sysfs files
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...

5716fb0d40 ahci: Add a generic 'controller2' RAID id
Intel server platforms that support 'RAID', i.e. have platform firmware
support for software-RAID metadata + features that the kernel also
understands, maintain the same device-ids for RAID from generation to
generation. This is in contrast to client platforms that have tended to
roll new device-ids every platform generation. However, even though
server platform keep the ids there are still unique device-ids per
controller instance. To date there have only been 2 controllers on these
platforms, but platforms code named Emmitsburg add a third controller.

Add the device-id for this third controller and collect it with the
other generic server RAID ids.

As mentioned here [1], the pain of continuing add new and different
device-ids for RAID mode to this file [2] has been heard. Ideally this
device-id would not matter and the class code would remain
PCI_CLASS_STORAGE_SATA_AHCI regardless of the RAID mode, but other
operating systems depend on the class code *not* being AHCI when the
device is in RAID mode. That said, going forward there is little reason
for new server RAID ids to be added as they can simply reuse one of the
existing ids even for a new controller. Server software RAID features
continue to be supported on Linux. Client software RAID features
continue to be not supported and the recommendation there remains to set
the device to AHCI mode in platform firmware.

4f1a22ee7b libata: Improve ATA queued command allocation
Improve ATA queued command allocation as follows:

- For attaining a qc tag for a SAS host we need to allocate a bit in
  ata_port.sas_tag_allocated bitmap.

  However we already have a unique tag per device in range
  [0, ATA_MAX_QUEUE -1] in the scsi cmnd budget token, so just use that
  instead.

- It is a bit pointless to have ata_qc_new_init() in libata-core.c since it
  pokes scsi internals, so inline it in ata_scsi_qc_new() (in
  libata-scsi.c). Also update Doc accordingly.

- Use standard SCSI helpers set_host_byte() and set_status_byte() in
  ata_scsi_qc_new().

Christoph Hellwig originally contributed the change to inline
ata_qc_new_init().

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."

02e2af20f4 Char/Misc and other driver updates for 5.18-rc1
Here is the big set of char/misc and other small driver subsystem
 updates for 5.18-rc1.
 
 Included in here are merges from driver subsystems which contain:
 	- iio driver updates and new drivers
 	- fsi driver updates
 	- fpga driver updates
 	- habanalabs driver updates and support for new hardware
 	- soundwire driver updates and new drivers
 	- phy driver updates and new drivers
 	- coresight driver updates
 	- icc driver updates
 
 Individual changes include:
 	- mei driver updates
 	- interconnect driver updates
 	- new PECI driver subsystem added
 	- vmci driver updates
 	- lots of tiny misc/char driver updates
 
 There will be two merge conflicts with your tree, one in MAINTAINERS
 which is obvious to fix up, and one in drivers/phy/freescale/Kconfig
 which also should be easy to resolve.
 
 All of these have been in linux-next for a while with no reported
 problems.

This series consists of the usual driver updates (qla2xxx, pm8001,
 libsas, smartpqi, scsi_debug, lpfc, iscsi, mpi3mr) plus minor updates
 and bug fixes.  The high blast radius core update is the removal of
 write same, which affects block and several non-SCSI devices.  The

d268afa1ff ata: pata_pxa: Use platform_get_irq() to get the interrupt
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().

ce70fd9a55 scsi: core: Remove the cmd field from struct scsi_request
Now that each scsi_request is backed by a scsi_cmnd, there is no need to
indirect the CDB storage.  Change all submitters of SCSI passthrough
requests to store the CDB information directly in the scsi_cmnd, and while
doing so allocate the full 32 bytes that cover all Linux supported SCSI
hosts instead of requiring dynamic allocation for > 16 byte CDBs.  On
64-bit systems this does not change the size of the scsi_cmnd at all, while
on 32-bit systems it slightly increases it for now, but that increase will
be made up by the removal of the remaining scsi_request fields.

Armada 3720 PHY driver (phy-mvebu-a3700-comphy.c) does not return
-EOPNOTSUPP from phy_power_on() callback anymore.

So remove AHCI_HFLAG_IGN_NOTSUPP_POWER_ON flag from Armada 3720 plat data.

AHCI_HFLAG_IGN_NOTSUPP_POWER_ON is not used by any other ahci driver, so
remove this flag completely.

The HPT371 chip physically has only one channel, the secondary one,
however the primary channel registers do exist! Thus we have to
manually disable the non-existing channel if the BIOS hasn't done this
already. Similarly to the pata_hpt3x2n driver, always disable the
primary channel.

03c0e84f9c ata: libata-sff: refactor ata_sff_altstatus()
The driver's calls to ata_sff_altstatus() are mostly surrounded by some
clumsy checks. Refactor ata_sff_altstatus() to include the repetitive
checks and return a 'bool' result indicating if the alternate status
register exists or not.

While at it, further update the 'kernel-doc' comment -- the alternate
status register has never been a part of the taskfile, despite what
Jeff and co. think! :-)

In ata_sff_lost_interrupt(), wrap the ata_sff_altstatus() call in a
WARN_ON_ONCE() check to issue a warning if the device control register
does not exist. And while at it, fix the strange argument indentation
in the ata_port_warn() call following the call to ata_sff_altstatus().

fda17afc61 ata: libata-core: Fix ata_dev_config_cpr()
The concurrent positioning ranges log page 47h is a general purpose log
page and not a subpage of the indentify device log. Using
ata_identify_page_supported() to test for concurrent positioning ranges
support is thus wrong. ata_log_supported() must be used.

Furthermore, unlike other advanced ATA features (e.g. NCQ priority),
accesses to the concurrent positioning ranges log page are not gated by
a feature bit from the device IDENTIFY data. Since many older drives
react badly to the READ LOG EXT and/or READ LOG DMA EXT commands isued
to read device log pages, avoid problems with older drives by limiting
the concurrent positioning ranges support detection to drives
implementing at least the ACS-4 ATA standard (major version 11). This
additional condition effectively turns ata_dev_config_cpr() into a nop
for older drives, avoiding problems in the field.

9b6d90e208 ata: pata_platform: Fix a NULL pointer dereference in __pata_platform_probe()
In __pata_platform_probe(), devm_kzalloc() is assigned to ap->ops and
there is a dereference of it right after that, which could introduce a
NULL pointer dereference bug.

Fix this by adding a NULL check of ap->ops.

This bug was found by a static analyzer.

Builds with 'make allyesconfig' show no new warnings,
and our static analyzer no longer warns about this code.

a17ab7aba5 ata: ahci: Add support for AMD A85 FCH (Hudson D4)
Add support for the AMD A85 FCH (Hudson D4) AHCI adapter.

Since this adapter does not require the default 200 ms debounce delay
in sata_link_resume(), create a new board board_ahci_no_debounce_delay
with the link flag ATA_LFLAG_NO_DEBOUNCE_DELAY, and, for now, configure
the AMD A85 FCH (Hudson D4) to use it. On the ASUS F2A85-M PRO it
reduces the Linux kernel boot time by the expected 200 ms from 787 ms
to 585 ms.

db6a3f47ce ata: pata_of_platform: Use platform_get_irq_optional() to get the interrupt
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_optional().

Note the code does not set the IRQ flags as this is handled
automatically for DT.

0561e514c9 ata: fix read_id() ata port operation interface
Drivers that need to tweak a device IDENTIFY data implement the
read_id() port operation. The IDENTIFY data buffer is passed as an
argument to the read_id() operation for drivers to use. However, when
this operation is called, the IDENTIFY data is not yet converted to CPU
endian and contains le16 words.

Change the interface of the read_id operation to pass a __le16 * pointer
to the IDENTIFY data buffer to clarify the buffer endianness. Fix the
pata_netcell, pata_it821x, ahci_xgene, ahci_ceva and ahci_brcm drivers
implementation of this operation and modify the code to corretly deal
with identify data words manipulation to avoid sparse warnings such as:

drivers/ata/ahci_xgene.c:262:33: warning: invalid assignment: &=

[-Werror=override-init]
 1385 |         .can_queue = SATA_FSL_QUEUE_DEPTH,

This is due to the driver scsi host template initialization overwriting
the can_queue field that is already set using the ATA_NCQ_SHT()
initializer macro, resulting in the same field being initialized twice
in the host template declaration.

To remove this warning, introduce the ATA_SUBBASE_SHT_QD() and
ATA_NCQ_SHT_QD() initialization macros to allow specifying a queue depth
different from the default ATA_DEF_QUEUE using an additional argument to
the macro.
