The hardware definition of every TPMI feature contains a major and minor
version. When there is a change in the MMIO offset or change in the
definition of a field, hardware will change major version. For addition
of new fields without modifying existing MMIO offsets or fields, only the
minor version is changed.
Driver is developed to support uncore frequency control (UFS) for a major
and minor version. If the hardware changes major version, since offsets
and definitions are changed, driver cannot continue to provide UFS
interface to users. Driver can still function with minor version change
as it will just miss the new functionality added by the hardware.
The current implementation logs information message and skips adding
uncore sysfs entry for a resource for any version mismatch. Check major
and minor version mismatch for every valid resource and fail on any major
version mismatch by logging an error message. A valid resource has a
version which is not 0xFF.
If there is mismatch with the minor version, continue with a log message.

Allowed level mask is a mask of levels, which are currently allowed to
dynamically switch by the OS. Fused mask is a mask of all levels even if
OS is not allowed to switch.
Even if OS is not allowed to dynamically switch, it is still possible for
user to boot to a level by using BIOS option. To decide which level to
boot next time, user wants to check parameters (power, performance or
thermal) of that level to decide.
So, when passing the level mask for display to user space, use fuse
enabled mask, which has all levels.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

On Lenovo platforms there is a limitation in the number of times an
attribute can be saved. This is an architectural limitation and it limits
the number of attributes that can be modified to 48.
A solution for this is instead of the attribute being saved after every
modification allow a user to bulk set the attributes and then trigger a
final save. This allows unlimited attributes.
This patch introduces a save_settings attribute that can be configured to
either single or bulk mode by the user.
Single mode is the default but customers who want to avoid the 48
attribute limit can enable bulk mode.
Displaying the save_settings attribute will display the enabled mode.
When in bulk mode writing 'save' to the save_settings attribute will
trigger a save. Once this has been done a reboot is required before more
attributes can be modified.

It's possible for interrupts to get significantly delayed to the point
that callers of intel_scu_ipc_dev_command() and friends can call the
function once, hit a timeout, and call it again while the interrupt
still hasn't been processed. This driver will get seriously confused if
the interrupt is finally processed after the second IPC has been sent
with ipc_command(). It won't know which IPC has been completed. This
could be quite disastrous if calling code assumes something has happened
upon return from intel_scu_ipc_dev_simple_command() when it actually
hasn't.
Let's avoid this scenario by simply returning -EBUSY in this case.
Hopefully higher layers will know to back off or fail gracefully when
this happens. It's all highly unlikely anyway, but it's better to be
correct here as we have no way to know which IPC the status register is
telling us about if we send a second IPC while the previous IPC is still
processing.

It's possible for the completion in ipc_wait_for_interrupt() to timeout,
simply because the interrupt was delayed in being processed. A timeout
in itself is not an error. This driver should check the status register
upon a timeout to ensure that scheduling or interrupt processing delays
don't affect the outcome of the IPC return value.
CPU0 SCU
---- ---
ipc_wait_for_interrupt()
wait_for_completion_timeout(&scu->cmd_complete)
[TIMEOUT] status[IPC_STATUS_BUSY]=0
Fix this problem by reading the status bit in all cases, regardless of
the timeout. If the completion times out, we'll assume the problem was
that the IPC_STATUS_BUSY bit was still set, but if the status bit is
cleared in the meantime we know that we hit some scheduling delay and we
should just check the error bit.

It's possible for the polling loop in busy_loop() to get scheduled away
for a long time.
status = ipc_read_status(scu); // status = IPC_STATUS_BUSY
<long time scheduled away>
if (!(status & IPC_STATUS_BUSY))
If this happens, then the status bit could change while the task is
scheduled away and this function would never read the status again after
timing out. Instead, the function will return -ETIMEDOUT when it's
possible that scheduling didn't work out and the status bit was cleared.
Bit polling code should always check the bit being polled one more time
after the timeout in case this happens.
Fix this by reading the status once more after the while loop breaks.
The readl_poll_timeout() macro implements all of this, and it is
shorter, so use that macro here to consolidate code and fix this.
There were some concerns with using readl_poll_timeout() because it uses
timekeeping, and timekeeping isn't running early on or during the late
stages of system suspend or early stages of system resume, but an audit
of the code concluded that this code isn't called during those times so
it is safe to use the macro.

Add support for the WMI methods used to turn off and adjust the
brightness of the secondary "screenpad" device found on some high-end
ASUS laptops like the GX650P series and others.
There are some small quirks with this device when considering only the
raw WMI methods:
1. The Off method can only switch the device off
2. Changing the brightness turns the device back on
3. To turn the device back on the brightness must be > 1
4. When the device is off the brightness can't be changed (so it is
stored by the driver if device is off).
5. Booting with a value of 0 brightness (retained by bios) means the bios
will set a value of >0 <15
6. When the device is off it is "unplugged"
asus_wmi sets the minimum brightness as 20 in general use, and 60 for
booting with values <= min.
The ACPI methods are used in a new backlight device named asus_screenpad.
