snd_hdac_display_power() doesn't handle the concurrent calls carefully enough, and it may lead to the doubly get_power or put_power calls, when a runtime PM and an async work get called in racy way. This patch addresses it by reusing the bus->lock mutex that has been used for protecting the link state change in ext bus code, so that it can protect against racy display state changes. The initialization of bus->lock was moved from snd_hdac_ext_bus_init() to snd_hdac_bus_init() as well accordingly. Testcase: igt/i915_pm_rpm/module-reload #glk-dsi Reported-by:

Commit 7769db58 ("drm/i915/dp: optimize eDP 1.4+ link config fast and narrow") started to optize the eDP 1.4+ link config, both per spec and as preparation for display stream compression support. Sadly, we again face panels that flat out fail with parameters they claim to support. Revert, and go back to the drawing board. v2: Actually revert to max params instead of just wide-and-slow.

A couple of machines in the farm show quite frequent errors in the powerwells not being released. Either there is an external agent interferring with the powerwells, or the powerwell doesn't quite behave as we anticipate -- either way, the test is not reliable enough to be enabled by default in CI. It has served its immediate purpose in providing coverage as we made tweaks to forcewake, so keep it available for future testing.

Push getting the reference for the encoders' power domains into the encoder get_power_domains() hook instead of doing this from the caller. This way the encoder can store away the corresponding wakerefs. This fixes the DSI encoder disabling, which didn't release these power references it acquired during HW state readout. Note that longtime ownership for the corresponding wakerefs can be thus acquired / released in two ways. Nevertheless there is always only one owner for them: After HW readout (booting/system resume): - encoder->get_power_domains() acquires - encoder->disable*() releases After a modeset (calling intel_atomic_commit()): - encoder->enable*() acquires - encoder->disable*() releases * can be any of the encoder enable/disable hooks. v2: - Check that the DSI io_wakerefs are unset both during encoder HW readout and enabling.

While transitioning to having better clarity between the modules, it's desirable to have the function name prefixes reflect the module. Functions in intel_foo.c should be prefixed intel_foo_. Expose only one CDCLK init/uninit function from intel_cdclk.c instead of one per platform. Obviously this adds one "unnecessary" if ladder within the entry points. However it should be considered more of a CDCLK implementation detail how this is done per platform, instead of exposing the fact. In other words, abstract the CDCLK module better.
