fd46821e85 power: supply: cpcap-battery: Add battery type auto detection for mapphone devices
This allows cpcap-battery to detect whitch battery is inserted, HW4X or
BW8X for xt875 and EB41 for xt894 by examining the battery nvmem. If no
known battery is detected sane defaults are used.

7f99cb5e60 x86/CPU/AMD: Use default_groups in kobj_type
There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the AMD mce sysfs code to use default_groups field which has
been the preferred way since

  aa30f47cf6 ("kobject: Add support for default attribute groups to kobj_type")

so that the obsolete default_attrs field can be removed soon.

57dfd7b53d KVM: x86: Move delivery of non-APICv interrupt into vendor code
Handle non-APICv interrupt delivery in vendor code, even though it means
VMX and SVM will temporarily have duplicate code.  SVM's AVIC has a race
condition that requires KVM to fall back to legacy interrupt injection
_after_ the interrupt has been logged in the vIRR, i.e. to fix the race,
SVM will need to open code the full flow anyways[*].  Refactor the code
so that the SVM bug without introducing other issues, e.g. SVM would
return "success" and thus invoke trace_kvm_apicv_accept_irq() even when
delivery through the AVIC failed, and to opportunistically prepare for
using KVM_X86_OP to fill each vendor's kvm_x86_ops struct, which will
rely on the vendor function matching the kvm_x86_op pointer name.

No functional change intended.

fe98a6137d ath11k: add debugfs for TWT debug calls
New debugfs files to manually add/delete/pause/resume TWT
dialogs for test/debug purposes.

The debugfs files expect the following parameters
- Add dialog
echo '<Peer_MAC> <Dialog_ID> <Wake_Interval_Usec> <Wake_Interval_Mantis>
 <Wake_Duration_Usec> <First_SP_Offset> <TWT_Command>
 <1:Broadcast /0:Individual> <1:Triggered / 0:Untriggered>
 <1:Unannounced /0:Announced> <1:Protected / 0:Unprotected>' >
 /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/add_dialog

Example (Non-triggered and un-announced):
echo '00:03:7F:20:13:52 1 102400 100 30720 20480 4 0 0 1 0' >
 /sys/kernel/debug/ieee80211/phy0/netdev:wlan0/twt/add_dialog

- Delete dialog
echo '<Peer_MAC> <Dialog_ID>' >
 /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/twt/del_dialog

f295ad9129 ath11k: Add debugfs interface to configure firmware debug log level
Add debugfs interface "fw_dbglog_config" to configure firmware log level.
Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID.

Command to configure,
echo "<dbglog_param> <values>" >
/sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

where dbglog_param can be,
  1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module
     here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel
  2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev
     here, <values> = vdev_id
  3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev
     except ERROR logs
     here, <values> = vdev_id
  4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap
       here, <values> = vdev_enable_bitmap
  5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the
     modules specified in the module bitmap. Command to configure for this log param,

     $ echo "5 <values> <module_id_index> <is_end>" >
         /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
     here,
                <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
                          'bb' - loglevel
                <module_id_index> = index of module bitmap. Max module id is 512.
                                    So, module_id_index is 0-15.
                <is_end> = to indicate if more configuration to follow.

  6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable.
     Command to configure for this log param,

      $ echo "6 <values> <module_id_index> <is_end>" >
          /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config
      here,
                 <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and
                              'bb' - loglevel
                 <module_id_index> = index of module bitmap. Max module id is 512.
                                     So, module_id_index is 0-15.
                 <is_end> = to indicate if more configuration to follow.

Sample command usage,

To enable module WLAN_MODULE_WMI and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "1 0x10001" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

To enable module bit map from 32 to 63 and log level ATH11K_FW_DBGLOG_VERBOSE,
echo "5 0xffffffff00000001 1 1" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config

d4f408cdcd power: supply: axp20x_battery: properly report current when discharging
As stated in [1], negative current values are used for discharging
batteries.

AXP PMICs internally have two different ADC channels for shunt current
measurement: one used during charging and one during discharging.
The values reported by these ADCs are unsigned.
While the driver properly selects ADC channel to get the data from,
it doesn't apply negative sign when reporting discharging current.

I was first going to just set M2/N2=M1/N1 but then it occurred
to me that it might interfere with fastboot on account of BIOS
likely leaving the registers zeroed. So let's zero out the values
instead (except TU where a zero register value actually means '1').
Still not sure that's the best approach but lets go with it for
now.

f0d4ce59f4 drm/i915: Disable DRRS on IVB/HSW port != A
Currently we allow DRRS on IVB PCH ports, but we're missing a
few programming steps meaning it is guaranteed to not work.
And on HSW DRRS is not supported on anything but port A ever
as only transcoder EDP has the M2/N2 registers (though I'm
not sure if HSW ever has eDP on any other port).

Starting from BDW all transcoders have the dynamically
reprogrammable M/N registers so DRRS could work on any
port.

Stop initializing DRRS on ports where it cannot possibly work.

be0c94ee21 drm/i915: Split intel_cpu_transcoder_set_m_n() into M1/N1 vs. M2/N2 variants
Make things a bit more explicit by splitting
intel_cpu_transcoder_set_m_n() into separate variants for M1/N1 vs.
M2/N2. Makes the DRRS M/N programming at least more obvious.

Note that for the MST and DRRS cases we don't need to call the
M2/N2 variant at all since the transcoders that support those
do not have the M2/N2 registers.

Same could be said for i9xx_crtc_enable() but I want to do a
higher level code sharing between that valleyview_crtc_enable()
later in which case we do need the M2/N2 variant. This is also
why I keep the transcoder_has_m2_n2() in intel_cpu_transcoder_set_m2_n2()
so the caller doesn't have necessarily care what the chosen
transcoder supports.

7d73c60215 drm/i915/pmu: Fix KMD and GuC race on accessing busyness
GuC updates shared memory and KMD reads it. Since this is not
synchronized, we run into a race where the value read is inconsistent.
Sometimes the inconsistency is in reading the upper MSB bytes of the
last_switch_in value. 2 types of cases are seen - upper 8 bits are zero
and upper 24 bits are zero. Since these are non-zero values, it is
not trivial to determine validity of these values. Instead we read the
values multiple times until they are consistent. In test runs, 3
attempts results in consistent values. The upper bound is set to 6
attempts and may need to be tuned as per any new occurences.

Since the duration that gt is parked can vary, the patch also updates
the gt timestamp on unpark before starting the worker.

v2:
- Initialize i
- Use READ_ONCE to access engine record

5ee32ea24c libbpf: Deprecate btf_ext rec_size APIs
btf_ext__{func,line}_info_rec_size functions are used in conjunction
with already-deprecated btf_ext__reloc_{func,line}_info functions. Since
struct btf_ext is opaque to the user it was necessary to expose rec_size
getters in the past.

btf_ext__reloc_{func,line}_info were deprecated in commit 8505e8709b
("libbpf: Implement generalized .BTF.ext func/line info adjustment")
as they're not compatible with support for multiple programs per
section. It was decided[0] that users of these APIs should implement their
own .btf.ext parsing to access this data, in which case the rec_size
getters are unnecessary. So deprecate them from libbpf 0.7.0 onwards.
