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.

The only bpc information in pipe registers for BXT/GLK DSI is the PIPEMISC dither bpc. Let's try to use that to read out pipe_bpp on these platforms. However, I'm not sure if this will be correctly populated by the GOP since bspec suggests it's only needed if dithering is actually enabled. If not I guess we'll have to go one step further and extract pipe_bpp from the DSI pixel format when dithering is disabled.

Haswell+ require many power wells to probe the current HW display state. Under the wakeref tracking scheme, we want each owner to store and release the wakeref they use, so we can identify callers that have leaked their wakeref. For hsw_get_pipe_config, this means we have to keep the array of all wakerefs as it current acquires its power wells piecemeal and releases them en masse. By tracking these wakerefs, we should be able to eliminate a lot of noise from the runtime-pm debug logs. Signed-off-by:
