Tegra20 doesn't have SMMU. Move out checking of the SMMU presence from
the SMMU driver into the Memory Controller driver. This change makes code
consistent in regards to how GART/SMMU presence checking is performed.

Splitting GART and Memory Controller wasn't a good decision that was made
back in the day. Given that the GART driver wasn't ever been used by
anything in the kernel, we decided that it will be better to correct the
mistakes of the past and merge two bindings into a single one. As a result
there is a DT ABI change for the Memory Controller that allows not to
break newer kernels using older DT and not to break older kernels using
newer DT, that is done by changing the 'compatible' of the node to
'tegra20-mc-gart' and adding a new-required clock property. The new clock
property also puts the tegra20-mc binding in line with the bindings of the
later Tegra generations.

Currently GART writes one page entry at a time. More optimal would be to
aggregate the writes and flush BUS buffer in the end, this gives map/unmap

UNAME26 is a mechanism to report Linux's version as 2.6.x, for
compatibility with old/broken software. Due to the way it is
implemented, it would have to be updated after 5.0, to keep the
resulting versions unique. Linus Torvalds argued:
"Do we actually need this?
I'd rather let it bitrot, and just let it return random versions. It
will just start again at 2.4.60, won't it?
Anybody who uses UNAME26 for a 5.x kernel might as well think it's
still 4.x. The user space is so old that it can't possibly care about
differences between 4.x and 5.x, can it?
The only thing that matters is that it shows "2.4.<largeenough>",
which it will do regardless"

A bigger batch than I anticipated this week, for two reasons:
- Some fallout on Davinci from board file -> DTB conversion, that also
includes a few longer-standing fixes (i.e. not recent regressions).
- drivers/reset material that has been in linux-next for a while, but
didn't get sent to us until now for a variety of reasons (maintainer out
sick, holidays, etc). There's a functional dependency in there such that
one platform (Altera's SoCFPGA) won't boot without one of the patches;
instead of reverting the patch that got merged, I looked at this set
and decided it was small enough that I'll pick it up anyway. If you
disagree I can revisit with a smaller set.
That being said, there's also a handful of the usual stuff:
- Fix for a crash on Armada 7K/8K when the kernel touches PSCI-reserved
memory
- Fix for PCIe reset on Macchiatobin (Armada 8K development board, what
this email is sent from in fact :)
- Enable a few new-merged modules for Amlogic in arm64 defconfig
- Error path fixes on Integrator
- Build fix for Renesas and Qualcomm
- Initialization fix for Renesas RZ/G2E
+ A few more fixlets.

Here is one small sysfs change, and a documentation update for 5.0-rc2
The sysfs change moves from using BUG_ON to WARN_ON, as discussed in an
email thread on lkml while trying to track down another driver bug.
sysfs should not be crashing and preventing people from seeing where
they went wrong. Now it properly recovers and warns the developer.
The documentation update removes the use of BUS_ATTR() as the kernel is
moving away from this to use the specific BUS_ATTR_RW() and friends
instead. There are pending patches in all of the different subsystems
to remove the last users of this macro, but for now, don't advertise it
should be used anymore to keep new ones from being introduced.

Commit 49e54187ae ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

We've always had a weird situation around dma_zalloc_coherent. To
safely support mapping the allocations to userspace major architectures
like x86 and arm have always zeroed allocations from dma_alloc_coherent,
but a couple other architectures were missing that zeroing either always
or in corner cases. Then later we grew anothe dma_zalloc_coherent
interface to explicitly request zeroing, but that just added __GFP_ZERO
to the allocation flags, which for some allocators that didn't end
up using the page allocator ended up being a no-op and still not
zeroing the allocations.
So for this merge window I fixed up all remaining architectures to zero
the memory in dma_alloc_coherent, and made dma_zalloc_coherent a no-op
wrapper around dma_alloc_coherent, which fixes all of the above issues.
dma_zalloc_coherent is now pointless and can go away, and Luis helped
me writing a cocchinelle script and patch series to kill it, which I
think we should apply now just after -rc1 to finally settle these
issue.

A feature has been added in the libahci driver: the possibility to set
a new flag in hpriv->flags to let the core handle PHY suspend/resume
automatically. Make use of this feature to make suspend to RAM work
with SATA drives on A3700.
Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
Signed-off-by: Jens Axboe <axboe@kernel.dk>
A3700 comphy initialization is done in the firmware (TF-A). Looking at
the SATA PHY initialization routine, there is a comment about "vendor
specific" registers. Two registers are mentioned. They are not
initialized there in the firmware because they are AHCI related, while
the firmware at this location does only PHY configuration. The
solution to avoid doing such initialization is relying on U-Boot.
While this work at boot time, U-Boot is definitely not going to run
during a resume after suspending to RAM.
Two possible solutions were considered:
* Fixing the firmware.
* Fixing the kernel driver.
The first solution would take ages to propagate, while the second
solution is easy to implement as the driver as been a little bit
reworked to prepare for such platform configuration. Hence, this patch
adds an Armada 3700 configuration function to set these two registers
both at boot time (in the probe) and after a suspend (in the resume
path).

At the beginning, only Armada 38x SoCs where supported by the
ahci_mvebu.c driver. Commit 15d3ce7b63 ("ata: ahci_mvebu: add
support for Armada 3700 variant") introduced Armada 3700 support. As
opposed to Armada 38x SoCs, the 3700 variants do not have to configure
mbus and the regret option. This patch took care of avoiding such
configuration when not needed in the probe function, but failed to do
the same in the resume path. While doing so looks harmless by
experience, let's clean the driver logic and avoid doing this useless
configuration with Armada 3700 SoCs.
Because the logic is very similar between these two places, it has
been decided to factorize this code and put it in a "Armada 38x
configuration function". This function is part of a new
(per-compatible) platform data structure, so that the addition of such
configuration function for Armada 3700 will be eased.

For Armada-38x (32-bit) SoCs, PM platform support has been added since:
commit 32f9494c9d ("ARM: mvebu: prepare pm-board.c for the
introduction of Armada 38x support")
commit 3cbd6a6ca8 ("ARM: mvebu: Add standby support")
For Armada 64-bit SoCs, like the A3700 also using this AHCI driver, PM
platform support has always existed.
There are even suspend/resume hooks in this driver since:
commit d6ecf15814 ("ata: ahci_mvebu: add suspend/resume support")
Remove the stale comment at the end of this driver stating that all
the above does not exist yet.

Current implementation of the libahci does not take into account the
new PHY framework. Correct the situation by adding a call to
phy_set_mode() before phy_power_on().
PHYs should also be handled at suspend/resume time. For this, call
ahci_platform_enable/disable_phys() at suspend/resume_host() time. These
calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of
the libahci driver must set manually in hpriv->flags at probe time. This
is to avoid breaking users that have not been tested with this change.
