a78b96fe95 platform/x86: thinkpad_acpi: rectify length of title underline
Commit d7cbe2773a ("platform/x86: thinkpad_acpi: set keyboard language")
adds information on keyboard setting to the thinkpad documentation, but
made the subsection title underline too short.

Hence, make htmldocs warns:

  Documentation/admin-guide/laptops/thinkpad-acpi.rst:1472: \
    WARNING: Title underline too short.

Rectify length of subsection title underline.

d7cbe2773a platform/x86: thinkpad_acpi: set keyboard language
This patch is to create sysfs entry for setting keyboard language
using ASL method. Some thinkpads models like T580 , T590 , T15 Gen 1
etc. has "=", "(',")" numeric keys, which are not displaying correctly,
when keyboard language is other than "english".
This patch fixes this issue by setting keyboard language to ECFW.

2324d50d05 It's been a busy cycle for documentation - hopefully the busiest for a
while to come.  Changes include:
 
  - Some new Chinese translations
 
  - Progress on the battle against double words words and non-HTTPS URLs
 
  - Some block-mq documentation
 
  - More RST conversions from Mauro.  At this point, that task is
    essentially complete, so we shouldn't see this kind of churn again for a
    while.  Unless we decide to switch to asciidoc or something...:)
 
  - Lots of typo fixes, warning fixes, and more.

acf7f4a591 platform/x86: thinkpad_acpi: lap or desk mode interface
Newer Lenovo Thinkpad platforms have support to identify whether the
system is on-lap or not using an ACPI DYTC event from the firmware.

This patch provides the ability to retrieve the current mode via sysfs
entrypoints and will be used by userspace for thermal mode and WWAN
functionality

6b2484e13a Replace HTTP links with HTTPS ones: Documentation/admin-guide
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.

110ea1d833 platform/x86: thinkpad_acpi: Add ThinkPad PrivacyGuard
This feature is found optionally in T480s, T490, T490s.

The feature is called lcdshadow and visible via
/proc/acpi/ibm/lcdshadow.

The ACPI methods \_SB.PCI0.LPCB.EC.HKEY.{GSSS,SSSS,TSSS,CSSS} are
available in these machines. They get, set, toggle or change the state
apparently.

The patch was tested on a 5.0 series kernel on a T480s.
