Linus Torvalds 6e207b8821 ARM: SoC changes for 5.14
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.

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/

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
ata3: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11
scsi host1: pata_legacy
ata4: PATA max PIO4 cmd 0x168 ctl 0x36e irq 10

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
consistent block.  Remove inaccuracies as follows:

- `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.

and it cause disks connected to these ports to be identified as removable
