The current tsens debugfs structure is composed by:
- a tsens dir in debugfs with a version file
- a directory for each tsens istance with sensors file to dump all the
sensors value.
This works on the assumption that we have the same version for each
istance but this assumption seems fragile and with more than one tsens
istance results in the version file not tracking each of them.
A better approach is to just create a subdirectory for each tsens
istance and put there version and sensors debugfs file.
Using this new implementation results in less code since debugfs entry
are created only on successful tsens probe.

Some processors issue more than one HFI interrupt with the same
timestamp. Each interrupt must be acknowledged to let the hardware issue
new HFI interrupts. But this can't be done without some additional flow
modification in the existing interrupt handling.
For background, the HFI interrupt is a package level thermal interrupt
delivered via a LVT. This LVT is common for both the CPU and package
level interrupts. Hence, all CPUs receive the HFI interrupts. But only
one CPU should process interrupt and others simply exit by issuing EOI
to LAPIC.
The current HFI interrupt processing flow:
1. Receive Thermal interrupt
2. Check if there is an active HFI status in MSR_IA32_THERM_STATUS
3. Try and get spinlock, one CPU will enter spinlock and others
will simply return from here to issue EOI.
(Let's assume CPU 4 is processing interrupt)
4. Check the stored time-stamp from the HFI memory time-stamp
5. if same
6. ignore interrupt, unlock and return
7. Copy the HFI message to local buffer
8. unlock spinlock
9. ACK HFI interrupt
10. Queue the message for processing in a work-queue
It is tempting to simply acknowledge all the interrupts even if they
have the same timestamp. This may cause some interrupts to not be
processed.
Let's say CPU5 is slightly late and reaches step 4 while CPU4 is
between steps 8 and 9.
Currently we simply ignore interrupts with the same timestamp. No
issue here for CPU5. When CPU4 acknowledges the interrupt, the next
HFI interrupt can be delivered.
If we acknowledge interrupts with the same timestamp (at step 6), there
is a race condition. Under the same scenario, CPU 5 will acknowledge
the HFI interrupt. This lets hardware generate another HFI interrupt,
before CPU 4 start executing step 9. Once CPU 4 complete step 9, it
will acknowledge the newly arrived HFI interrupt, without actually
processing it.
Acknowledge the interrupt when holding the spinlock. This avoids
contention of the interrupt acknowledgment.
Updated flow:
1. Receive HFI Thermal interrupt
2. Check if there is an active HFI status in MSR_IA32_THERM_STATUS
3. Try and get spin-lock
Let's assume CPU 4 is processing interrupt
4.1 Read MSR_IA32_PACKAGE_THERM_STATUS and check HFI status bit
4.2 If hfi status is 0
4.3 unlock spinlock
4.4 return
4.5 Check the stored time-stamp from the HFI memory time-stamp
5. if same
6.1 ACK HFI Interrupt,
6.2 unlock spinlock
6.3 return
7. Copy the HFI message to local buffer
8. ACK HFI interrupt
9. unlock spinlock
10. Queue the message for processing in a work-queue
To avoid taking the lock unnecessarily, intel_hfi_process_event() checks
the status of the HFI interrupt before taking the lock. If CPU5 is late,
when it starts processing the interrupt there are two scenarios:
a) CPU4 acknowledged the HFI interrupt before CPU5 read
MSR_IA32_THERM_STATUS. CPU5 exits.
b) CPU5 reads MSR_IA32_THERM_STATUS before CPU4 has acknowledged the
interrupt. CPU5 will take the lock if CPU4 has released it. It then
re-reads MSR_IA32_THERM_STATUS. If there is not a new interrupt,
the HFI status bit is clear and CPU5 exits. If a new HFI interrupt
was generated it will find that the status bit is set and it will
continue to process the interrupt. In this case even if timestamp
is not changed, the ACK can be issued as this is a new interrupt.

The clearing of the package thermal status is done by Read-Modify-Write
operation. This may result in clearing of some new status bits which are
being or about to be processed.
For example, while clearing of HFI status, after read of thermal status
register, a new thermal status bit is set by the hardware. But during
write back, the newly generated status bit will be set to 0 or cleared.
So, it is not safe to do read-modify-write.
Since thermal status Read-Write bits can be set to only 0 not 1, it is
safe to set all other bits to 1 which are not getting cleared.
Create a common interface for clearing package thermal status bits. Use
this interface to replace existing code to clear thermal package status
bits.
It is safe to call from different CPUs without protection as there is no
read-modify-write. Also wrmsrl results in just single instruction. For
example while CPU 0 and CPU 3 are clearing bit 1 and 3 respectively. If
CPU 3 wins the race, it will write 0x4000aa2, then CPU 1 will write
0x4000aa8. The bits which are not part of clear are set to 1. The default
mask for bits, which can be written here is 0x4000aaa.

When there is a package thermal interrupt with PROCHOT log, it will be
processed and cleared. It is possible that there is an active HFI event
status, which is about to get processed or getting processed. While
clearing PROCHOT log bit, it will also clear HFI status bit. This means
that hardware is free to update HFI memory.
When clearing a package thermal interrupt, some processors will generate
a "general protection fault" when any of the read only bit is set to 1.
The driver maintains a mask of all read-write bits which can be set.
This mask doesn't include HFI status bit. This bit will also be cleared,
as it will be assumed read-only bit. So, add HFI status bit 26 to the
mask.

This reverts commit 72a9585972.
It broke reboots on big-endian MIPS and MIPS64 malta QEMU instances,
which use the syscon driver. Little-endian is not effected, which means
likely it's important to handle regmap_get_val_endian() in this function
after all.
Fixes: 72a9585972 ("mfd: syscon: Remove repetition of the regmap_get_val_endian()")
