Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines,
corresponding to the 80 status bits available in hardware. Each of these
lines can be configured as either an input or an output.
However, each of these GPIOs is actually an input *and* an output; we
actually have 80 inputs plus 80 outputs.
This change expands the maximum number of GPIOs to 160; the lower half
of this range are the input-only GPIOs, the upper half are the outputs.
We fix the GPIO directions to correspond to this mapping.
This also fixes a bug when setting GPIOs - we were reading from the
input register, making it impossible to set more than one output GPIO.

The MediaTek MMC driver uses pointer to get from private
msdc_host structure to the generic mmc_host structure.
However mmc_host always precedes msdc_host in memory so compute
its address with a subtraction (which is cheaper than a dereference)
using mmc_from_priv() and drop the extra pointer.

A struct device is a dynamic structure, with reference counting.
"Tricking" the kernel to make a dynamic structure static, by working
around the driver core release detection logic, is not nice.
Because of this, this code has been used as an example for others on
"how to do things", which is just about the worst thing possible to have
happen.
Fix this all up by making the platform device dynamic and providing a
real release function.

Pavilion 11 x360
Commit cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist
SW_TABLET_MODE on the 9 / "Laptop" chasis-type") restored SW_TABLET_MODE
reporting on the HP stream x360 11 series on which it was previously broken
by commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet
mode switch on 2-in-1's").
It turns out that enabling SW_TABLET_MODE reporting on devices with a
chassis-type of 10 ("Notebook") causes SW_TABLET_MODE to always report 1
at boot on the HP Pavilion 11 x360, which causes libinput to disable the
kbd and touchpad.
The HP Pavilion 11 x360's ACPI VGBS method sets bit 4 instead of bit 6 when
NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection
shows only one other model, the Medion E1239T ever setting bit 4 and it
always sets this together with bit 6.
So lets treat bit 4 as a second bit which when set indicates the device not
being in tablet-mode, as we already do for bit 6.
While at it also prefix all VGBS constant defines with "VGBS_".

processor or memory
Note this crash is present before any of the patches in this series, but
as explained below it is highly unlikely anyone is shipping a firmware that
causes it. Tests were done using an overriden SRAT.
On ARM64, the gic-v3 driver directly parses SRAT to locate GIC Interrupt
Translation Service (ITS) Affinity Structures. This is done much later
in the boot than the parses of SRAT which identify proximity domains.
As a result, an ITS placed in a proximity domain that is not defined by
another SRAT structure will result in a NUMA node that is not completely
configured and a crash.

ACPI 6.3 allows any set of Affinity Structures in SRAT to define a proximity
domain. However, as we do not see this crash, we can conclude that no
firmware is currently placing an ITS in a node that is separate from
those containing memory and / or processors.
We could modify the SRAT parsing behavior to identify the existence
of Proximity Domains unique to the ITS structures, and handle them as
a special case of a generic initiator (once support for those merges).
This patch avoids the complexity that would be needed to handle this corner
case, by not allowing the ITS entry parsing code to instantiate new NUMA
Nodes. If one is encountered that does not already exist, then NO_NUMA_NODE
is assigned and a warning printed just as if the value had been greater than
allowed NUMA Nodes.
"SRAT: Invalid NUMA node -1 in ITS affinity"
Whilst this does not provide the full flexibility allowed by ACPI,
it does fix the problem. We can revisit a more sophisticated solution if
needed by future platforms.
Change is simply to replace acpi_map_pxm_to_node with pxm_to_node reflecting
the fact a new mapping is not created.

acpi_get_node() calls acpi_get_pxm() to evaluate the _PXM AML method
for entries found in DSDT/SSDT. ACPI 6.3 sec 6.2.14 states
"_PXM evaluates to an integer that identifies a device as belonging to
a Proximity Domain defined in the System Resource Affinity Table (SRAT)."
Hence a _PXM method should not result in creation of a new NUMA node.
Before this patch, _PXM could result in partial instantiation of
NUMA node, missing elements such as zone lists. A call to
devm_kzalloc(), for example, results in a NULL pointer dereference.
This patch therefore replaces the acpi_map_pxm_to_node() with a call
to pxm_to_node().

acpi_map_pxm_to_online_node()
While this function will only return an online node, it can have the side
effect of partially creating a new node. The existing comments suggest this
is intentional, but the usecases of this function are related to NFIT and
HMAT parsing, neither of which should be able to define new nodes.
One route by which the existing behaviour would cause a crash is to have a
_PXM entry in ACPI DSDT attempt to place a device within this partly
created proximity domain. A subsequent call to devm_kzalloc() or similar
would result in an attempt to allocate memory on a node for which zone
lists have not been set up and a NULL pointer dereference.
Prevent such cases by switching to pxm_to_node() within
acpi_map_pxm_to_online_node() which cannot cause a new node to be
partly created. If one would previously have been created we now
return NO_NUMA_NODE. Documentation updated to reflect this change.

Several ACPI static tables contain references to proximity domains.
ACPI 6.3 has clarified that only entries in SRAT may define a new
domain (sec 5.2.16).
Those tables described in the ACPI spec have additional clarifying text.
NFIT: Table 5-132,
"Integer that represents the proximity domain to which the memory
belongs. This number must match with corresponding entry in the
SRAT table."
HMAT: Table 5-145,
"... This number must match with the corresponding entry in the SRAT
table's processor affinity structure ... if the initiator is a processor,
or the Generic Initiator Affinity Structure if the initiator is a generic
initiator".
IORT and DMAR are defined by external specifications.
Intel Virtualization Technology for Directed I/O Rev 3.1 does not make any
explicit statements, but the general SRAT statement above will still apply.
https://software.intel.com/sites/default/files/managed/c5/15/vt-directed-io-spec.pdf
IO Remapping Table, Platform Design Document rev D, also makes not explicit
statement, but refers to ACPI SRAT table for more information and again the
generic SRAT statement above applies.
https://developer.arm.com/documentation/den0049/d/
In conclusion, any proximity domain specified in these tables, should be a
reference to a proximity domain also found in SRAT, and they should not be
able to instantiate a new domain. Hence we switch to pxm_to_node() which
will only return existing nodes.

Whilst hardening this code may be good in general, the main intent
here is to enable following patches that use this function to replace

NO_NUMA_NODE for PXM entries not matching with those in SRAT.

IOMMU SNP support requires the completion wait write-back semaphore to be
implemented using a 4K-aligned page, where the page address is to be
programmed into the newly introduced MMIO base/range registers.
This new scheme uses a per-iommu atomic variable to store the current
semaphore value, which is incremented for every completion wait command.
Since this new scheme is also compatible with non-SNP mode,
generalize the driver to use 4K page for completion-wait semaphore in
both modes.

There can be clients using the same swgroup in DT, for example i2c0
and i2c1. The current driver will add them to separate IOMMU groups,
though it has implemented device_group() callback which is to group
devices using different swgroups like DC and DCB.
All clients having the same swgroup should be also added to the same
IOMMU group so as to share an asid. Otherwise, the asid register may
get overwritten every time a new device is attached.

The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.
To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.
Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode. I have another patch fixing the LED
issue in a different manner.
Note this is the second time the we revert the adding of the
asus_nb_wmi_blacklist. It was reverted before in commit:
aab9e7896ec9 ("platform/x86: asus-nb-wmi: Revert "Do not load on Asus
T100TA and T200TA")"
But some how (accidentally re-applying of the patch?) it got re-added
again in commit 3bd12da7f50b ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA"), so now we need to revert it again.

A 100MHZ 32-bit timer will be wrapped up less than 43s. Although the
kernel maintains a software high 32-bit count in the tick IRQ. But it's
not applicable to the user mode APPs.
Note: The kernel still uses the lower 32 bits of the timer.

The ARM SP804 supports a maximum of 32-bit counter, but Hisilicon extends
it to 64-bit. That means, the registers: TimerXload, TimerXValue and
TimerXBGLoad are 64bits, all other registers are the same as those in the
SP804. The driver code can be completely reused except that the register
offset is different.
Use compatible = "hisilicon,sp804" mark as Hisilicon sp804 timer.

TimerXBGLoad are 64bits, all other registers are the same as those in the
SP804. The driver code can be completely reused except that the register
offset is different.
Currently, we get a timer register address by: add the constant register
offset to the timer base address. e.g. "base + TIMER_CTRL". It can not be
dynamically adjusted at run time.
So create a new structure "sp804_timer" to record the original registers
offset, and create a new structure "sp804_clkevt" to record the
calculated registers address. So the "base + TIMER_CTRL" is changed to
"clkevt->ctrl", this will faster than "base + timer->ctrl".
For example:
struct sp804_timer arm_sp804_timer = {
.ctrl = TIMER_CTRL,
};
struct sp804_clkevt clkevt;
clkevt.ctrl = base + arm_sp804_timer.ctrl.
- writel(0, base + TIMER_CTRL);
+ writel(0, clkevt->ctrl);

Add two local variables: timer1_base and timer2_base in sp804_of_init(),
to avoid repeatedly calculate the base address of timer2, and make it
easier to recognize timer1. Hope to make the next patch looks more clear.

The timer is just temporarily disabled, and it will be set to periodic
mode later.

0 = Timer module is in free-running mode (default)

Originally we used the term "encrypted name" or "ciphertext name" to
mean the encoded filename that is shown when an encrypted directory is
listed without its key. But these terms are ambiguous since they also
mean the filename stored on-disk. "Encrypted name" is especially
ambiguous since it could also be understood to mean "this filename is
encrypted on-disk", similar to "encrypted file".
So we've started calling these encoded names "no-key names" instead.
Therefore, rename DCACHE_ENCRYPTED_NAME to DCACHE_NOKEY_NAME to avoid
confusion about what this flag means.

Currently we're using the term "ciphertext name" ambiguously because it
can mean either the actual ciphertext filename, or the encoded filename
that is shown when an encrypted directory is listed without its key.
The latter we're now usually calling the "no-key name"; and while it's
derived from the ciphertext name, it's not the same thing.
To avoid this ambiguity, rename fscrypt_name::is_ciphertext_name to
fscrypt_name::is_nokey_name, and update comments that say "ciphertext
name" (or "encrypted name") to say "no-key name" instead when warranted.

EEE should be only be enabled during stmmac_mac_link_up() when the
link are up and being set up properly. set_eee should only do settings
configuration and disabling the eee.
Without this fix, turning on EEE using ethtool will return
"Operation not supported". This is due to the driver is in a dead loop
waiting for eee to be advertised in the for eee to be activated but the
driver will only configure the EEE advertisement after the eee is
activated.
Ethtool should only return "Operation not supported" if there is no EEE
capbility in the MAC controller.
