All MG/DKL PHY register regions are evenly spaced offset-wise (0x168000, 0x169000, 0x16A000, 0x16B000) so the _MMIO_PORT() macro we use to access their registers only needs the first two offsets.

2021-12-16drm/i915/backlight: Make ext_pwm_disable_backlight() call ↵Hans de Goede
intel_backlight_set_pwm_level() At least the Bay Trail LPSS PWM controller used with DSI panels on many Bay Trail tablets seems to leave the PWM pin in whatever state it was (high or low) ATM that the PWM gets disabled. Combined with some panels not having a separate backlight-enable pin this leads to the backlight sometimes staying on while it should not (when the pin was high during PWM-disabling). First calling intel_backlight_set_pwm_level() will ensure that the pin is always low (or high for inverted brightness panels) since the passed in duty-cycle is 0% (or 100%) when the PWM gets disabled fixing the backlight sometimes staying on. With the exception of ext_pwm_disable_backlight() all other foo_disable_backlight() functions call intel_backlight_set_pwm_level() already before disabling the backlight, so this change also aligns ext_pwm_disable_backlight() with all the other disable() functions.

intel_cdclk.h only needs i915_drv.h for struct intel_cdclk_config. Move the definition to intel_cdclk.h and turn the includes around to avoid including i915_drv.h from other headers. The intel cdclk state macros in intel_cdclk.h still reference struct drm_i915_private, but as macros they don't strictly require the definition until they are used. v2: Expand on the commit message wrt cdclk state macros Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211213114106.296017-1-jani.nikula@intel.com

2021-12-13drm/i915: Move pipe/transcoder/abox masks under intel_device_info.displayVille Syrjälä
Collect the dipslay related mask under the display sub-structure in intel_device_info. Note that there is a slight change in behaviour in that we zero out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so now we also zero out the other masks (although cpu_transocder_mask should already be zero of pipe_mask is zero). abox_mask is only used by the display core init when HAS_DISPLAY is true, so the actual behaviour of the system shouldn't change despite the zeroing of these masks. There is a lot more display stuff directly in device info that could be moved over. Maybe someone else will be inspired to do it...
