[SRU][R][PATCH 00/13] Patchset for TUXEDO devices

[Werner Sembach]

Buglink: https://bugs.launchpad.net/bugs/2152570

Impact: This is a patchset that we (TUXEDO Computers) currently apply on top of the Ubuntu 7.0 kernel to make it run smoothly on all our devices. All patches apply smoothly to 7.0.
Fix: All these patches are already upstream (in 7.1) except the last one.
Testcase: We run this patchset for all our customers devices (we basically maintain our own OEM branch) so it is quite field testet. Besides that, whenever a new patch was added we did regression testing on a selection of devices.

Prevent setting unsupported refreshrates when the eDP display supports higher refresh rates then the Intel iGPU:
- drm/i915/vbt: Add edp pipe joiner enable/disable bits
- drm/i915/dp: Avoid joiner for eDP if not enabled in VBT

Prevent screen freeze on some devices with AMD iGPU:
- drm/amd/display: Add Idle state manager(ISM)

Fix display backlight of eDP display not working on some older devices:
- drm/i915/backlight: Remove try_vesa_interface
- drm/i915/backlight: Use intel_panel variable instead of intel_connector
- drm/i915/backlight: Take luminance_set into account for VESA backlight
- drm/i915/backlight: Check luminance_set when disabling PWM via AUX VESA backlight
- drm/i915/backlight: Short circuit intel_dp_aux_supports_hdr_backlight
- drm/i915/backlight: Update debug log during backlight setup
- drm/i915/backlight: Provide clear description on how backlight level is controlled
- drm/i915/backlight: Check if VESA backlight is possible
- drm/i915/backlight: Fix VESA backlight possible check condition

Fix rare freeze on some Intel iGPUs:
- drm: ensure that vblank diff is never negative
