Currently, k10temp_get_ccd_support() takes as input "pdev" and "data". However,
"pdev" is already included in "data". Furthermore, the "pdev" parameter is no
longer used in k10temp_get_ccd_support(), since its use was moved into
read_ccd_temp_reg().
Drop the "pdev" input parameter as it is no longer needed.
No functional change is intended.

The CCD temperature register is read in two places. These reads are done
using an AMD SMN access, and a number of parameters are needed for the
operation.
Move the SMN access and parameter gathering into a helper function in order to
simplify the code flow. This also has a benefit of centralizing the hardware
register access in a single place in case fixes or special decoding is required.

Check the return value of amd_smn_read() before saving a value. This
ensures invalid values aren't saved or used.
There are three cases here with slightly different behavior:
1) read_tempreg_nb_zen():
This is a function pointer which does not include a return code.
In this case, set the register value to 0 on failure. This
enforces Read-as-Zero behavior.
2) k10temp_read_temp():
This function does have return codes, so return the error code
from the failed register read. Continued operation is not
necessary, since there is no valid data from the register.
Furthermore, if the register value was set to 0, then the
following operation would underflow.
3) k10temp_get_ccd_support():
This function reads the same register from multiple CCD
instances in a loop. And a bitmask is formed if a specific bit
is set in each register instance. The loop should continue on a
failed register read, skipping the bit check.

Industrial processor i3255 supports temperatures -40 deg celcius
to 105 deg Celcius. The current implementation of k10temp_read_temp
rounds off any negative temperatures to '0'. To fix this,
the following changes have been made.
A flag 'disp_negative' is added to struct k10temp_data to support
AMD i3255 processors. Flag 'disp_negative' is set if 3255 processor
is found during k10temp_probe. Flag 'disp_negative' is used to
determine whether to round off negative temperatures to '0' in
k10temp_read_temp.

Voltages and current are reported by Zen CPUs. However, the means
to do so is undocumented, changes from CPU to CPU, and the raw data
is not calibrated. Calibration information is available, but again
not documented. This results in less than perfect user experience,
up to concerns that loading the driver might possibly damage
the hardware (by reporting out-of range voltages). Effectively
support for reporting voltages and current is not maintainable.

The debugfs code was intended to aid figuring out functionality
of undocumented registers. Turns out that wasn't very helpful,
since register locations change too much between AMD chip revisions,
and the data isn't really valuable for chips where it isn't already
supported. On top of that, its existence has been used as argument
for providing pseudo-API debugfs functions in other drivers.
So let's just take it out.

Traditionally, the temperature displayed by k10temp was Tctl.
On Family 17h CPUs, Tdie was displayed instead. To reduce confusion,
Tctl was added later as second temperature. This resulted in Tdie
being reported as temp1_input, and Tctl as temp2_input. This is
different to non-Ryzen CPUs, where Tctl is displayed as temp1_input.
Swap temp1_input and temp2_input on Family 17h CPUs, such that Tctl
is now reported as temp1_input and Tdie is reported as temp2_input,
to align with other CPUs, streamline the code, and make it less
confusing. Coincidentally, this also aligns the code with its
documentation, which states that Tdie is reported as temp2_input.

In HWiNFO, we see support for Tccd1, Tccd3, Tccd5, and Tccd7 temperature
sensors on Zen2 based Threadripper CPUs. Checking register maps on
Threadripper 3970X confirms SMN register addresses and values for those
sensors.
Register values observed in an idle system:
0x059950: 00000000 00000abc 00000000 00000ad8
0x059960: 00000000 00000ade 00000000 00000ae4
Under load:
0x059950: 00000000 00000c02 00000000 00000c14
0x059960: 00000000 00000c30 00000000 00000c22
More analysis shows that EPYC CPUs support up to 8 CCD temperature
sensors. EPYC 7601 supports three CCD temperature sensors. Unlike
Zen2 CPUs, the register space in Zen1 CPUs supports a maximum of four
sensors, so only search for a maximum of four sensors on Zen1 CPUs.
On top of that, in thm_10_0_sh_mask.h in the Linux kernel, we find
definitions for THM_DIE{1-3}_TEMP__VALID_MASK, set to 0x00000800, as well
as matching SMN addresses. This lets us conclude that bit 11 of the
respective registers is a valid bit. With this assumption, the temperature
offset is now 49 degrees C. This conveniently matches the documented
temperature offset for Tdie, again suggesting that above registers indeed
report temperatures sensor values. Assume that bit 11 is indeed a valid
bit, and add support for the additional sensors.
With this patch applied, output from 3970X (idle) looks as follows:
k10temp-pci-00c3
Adapter: PCI adapter
Tdie: +55.9°C
Tctl: +55.9°C
Tccd1: +39.8°C
Tccd3: +43.8°C
Tccd5: +43.8°C
Tccd7: +44.8°C

The maximum Tdie or Tctl is not published for Ryzen CPUs. What is
known, however, is that the traditional value of 70 degrees C is no
longer correct. On top of that, the limit applies to Tctl, not to Tdie.
Displaying it in either context is meaningless, confusing, and wrong.

It would seem like model 70h is behaving in the same way as model 30h,
so let's just add the new F3 PCI ID to the list of compatible devices.
Unlike previous Ryzen/Threadripper, Ryzen gen 3 processors do not need
temperature offsets anymore. This has been reported in the press and
verified on my Ryzen 3700X by checking that the idle temperature
reported by k10temp is matching the temperature reported by the
firmware.
Vicki Pfau sent an identical patch after I checked that no-one had
written this patch. I would have been happy about dropping my patch but
unlike for his patch series, I had already Cc:ed the x86 people and
they already reviewed the changes. Since Vicki has not answered to

Add support for Hygon Dhyana family 18h processor for k10temp to get the
temperature. As Hygon Dhyana shares the same function interface with AMD
family 17h, so add Hygon PCI Vendor ID and reuse the code path of AMD.

Add support for AMD family 17h model 30h processors for k10temp. Model
30h is functionally the same as model 01h processors (as far as k10temp
is concerned), just the PCI device IDs need to be updated.

BIOS developer guides refer to Family 15h Models 60h-6fh and Family 15h
Models 70h-7fh. So far the driver only checked for Models 60h and 70h.
However, there are now processors with other model numbers in the same
families. Example is A10-9620P family 15h model 65h. Follow the developer
guides and mask the lower 4 bit of the model number to determine the
registers to use for reading temperatures and temperature limits.

All announced Threadripper 29xx models have a temperature offset of
27 degrees C. Simplify temperature offset table to match all 29xx
Threadripper models with a single entry. Also simplify the table to match
all 19xx Threadripper models with a single entry. This effectively drops
entries for Threadripper 1910/1920/1950 which never saw the light of day.

For at least the Threadripper 2950X and Threadripper 2990WX,
it's confirmed a 27 degree offset is needed.

The function get_raw_temp is local to the source and does not need to
be in global scope, so make it static.
Cleans up sparse warning:
drivers/hwmon/k10temp.c:149:14: warning: symbol 'get_raw_temp' was not
declared. Should it be static?
