Older controllers use SCSI target id '0' for the first internal disk. As
the controllers are now placed on the same bus as the internal disks
this leads to a clash with the SCSI target id of controller. This patch
checks the SCSI revision, and moves older controller to bus '3' to be
compatible with older releases and avoid this problem.

Pull thermal management fix from Zhang Rui:
"We only have one urgent fix this time.
Commit 3105f234e0ab ("thermal/powerclamp: correct cpu support check"),
which is shipped in 4.9-rc3, fixed a problem introduced by commit
b721ca0d1927 ("thermal/powerclamp: remove cpu whitelist").
But unfortunately, it broke intel_powerclamp driver module auto-
loading at the same time. Thus we need this change to add back module
auto-loading for 4.9"

One prevents timeouts on mpt3sas when trying to use the secure erase

a regression in a prior fix which causes all commands to abort during
PCI extended error recovery, which is incorrect because PCI EEH is

While testing HDMI with Xorg on the Juno board, I find that when Xorg
starts up or shuts down, the display is shifted significantly to the
right and wrapped in the active region. (No sync bars are visible.)
The timings are correct, it behaves as if the start address has been
shifted many pixels _into_ the framebuffer.
This occurs whenever the display mode size is changed - using xrandr
in Xorg shows that changing the resolution triggers the problem
almost every time, but changing the refresh rate does not.
Using devmem2 to disable and re-enable the HDLCD resolves the issue,
and repeated disable/enable cycles do not make the issue re-appear.
Further debugging shows that we try to update the controller
configuration while enabled.
Alwys ensure that the HDLCD is disabled prior to updating the
controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on()
so that DRM knows whether it can expect vblank interrupts.

I totally butcherd the job on typing the kernel-doc for these, and no
one realized. Noticed by Russell. Maarten has a more complete approach
to this confusion, by making it more explicit what the new/old state
is, instead of this magic switching behaviour.
v2:
- Liviu pointed out that wait_for_fences is even more magic. Leave
that as @state, and document @pre_swap better.
- While at it, patch in header for the reference section.
- Fix spelling issues Russell noticed.
v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/,
since async flip is something else than non-blocking.

The WDAT watchdog driver uses functionality provided by the watchdog timer

The PLL-MIPI clock is somewhat special as it has its own LDOs which
need to be turned on for this PLL to actually work and output a clock
signal.
Add the 2 LDO enable bits to the gate bits. This fixes issues with
the TCON not sending vblank interrupts when the tcon and dot clock are
indirectly clocked from the PLL-MIPI clock.

Somehow I ended up with an off-by-three error in calculating the size of
the PASID and PASID State tables, which triggers allocations failures as
those tables unfortunately have to be physically contiguous.
In fact, even the *correct* maximum size of 8MiB is problematic and is
wont to lead to allocation failures. Since I have extracted a promise
that this *will* be fixed in hardware, I'm happy to limit it on the
current hardware to a maximum of 0x20000 PASIDs, which gives us 1MiB
tables — still not ideal, but better than before.
Reported by Mika Kuoppala <mika.kuoppala@linux.intel.com> and also by
Xunlei Pang <xlpang@redhat.com> who submitted a simpler patch to fix
only the allocation (and not the free) to the "correct" limit... which
was still problematic.

Let's add a couple more BUG_ONs before this to ascertain that the request
did make it to hardware. The impossible part of this stacktrace is that
request must have been considered completed by the i915_request_wait()

When gathering the pages from our backing storage we expect get_pages()
to either give us our sg_table or an err ptr. However when gathering our
fake pages for stolen memory we may return NULL in the event of a
failure. To prevent any funny business we should therefore return the
proper err ptr value.

sunbmac uses '__u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enables 64bit
DMA and therefore dma_addr_t becomes of type u64. This makes
'incompatible pointer type' warnings inevitable.
e.g.
drivers/net/ethernet/sun/sunbmac.c: In function ‘bigmac_ether_init’:
drivers/net/ethernet/sun/sunbmac.c:1166: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type

Make sure to deregister all child devices also on probe errors to avoid
leaks and to fix probe deferral:
cpsw 4a100000.ethernet: omap_device: omap_device_enable() called from invalid state 1
cpsw 4a100000.ethernet: use pm_runtime_put_sync_suspend() in driver?
cpsw: probe of 4a100000.ethernet failed with error -22
Add generic helper to undo the effects of cpsw_probe_dt(), which will
also be used in a follow-on patch to fix further leaks that have been
introduced more recently.
Note that the platform device is now runtime-resumed before registering
any child devices in order to make sure that it is synchronously
suspended after having deregistered the children in the error path.

This is caused by the sky2 being called after it has been shutdown.
A previous thread about this can be found here:
https://lkml.org/lkml/2016/4/12/410
An alternative fix is to assure that IFF_UP gets cleared by
calling dev_close() during shutdown. This is similar to what the
bnx2/tg3/xgene and maybe others are doing to assure that the driver
isn't being called following _shutdown().

Pull GPIO fixes from Linus Walleij:
"These are hopefully the last GPIO fixes for v4.9. The most important
is that it fixes the UML randconfig builds that have been nagging me
for some time and me being confused about where the problem was really
sitting, now this fix give this nice feeling that everything is solid
and builds fine.
Summary:
- Finally, after being puzzled by a bunch of recurrent UML build
failures on randconfigs from the build robot, Keno Fischer nailed
it: GPIO_DEVRES is optional and depends on HAS_IOMEM even though
many users just unconditionally rely on it to be available. And it
*should* be available: garbage collection is nice for this and it
*certainly* has nothing to do with having IOMEM. So we got rid of
it, and now the UML builds should JustWork(TM).
- Do not call .get_direction() on sleeping GPIO chips on the fastpath
when locking GPIOs for interrupts: it is done from atomic context,
no way.
- Some driver fixes"
* tag 'gpio-v4.9-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio: Remove GPIO_DEVRES option

Since commit 87a18a6a5652 ("mmc: mmc: Use ->card_busy() to detect busy
cards in __mmc_switch()") the ESDHC driver is broken:
mmc0: Card stuck in programming state! __mmc_switch
mmc0: error -110 whilst initialising MMC card
Since this commit __mmc_switch() uses ->card_busy(), which is
sdhci_card_busy() for the esdhc driver. sdhci_card_busy() uses the
PRESENT_STATE register, specifically the DAT0 signal level bit. But the
ESDHC uses a non-conformant PRESENT_STATE register, thus a read fixup is
required to make the driver work again.
