drm/i915: move modesetting output/encoder code under display/
Add a new subdirectory for display code, and start off by moving modesetting output/encoder code. Judging by the include changes, this is a surprisingly clean operation. v2: - move intel_sdvo_regs.h too - use tabs for Makefile file lists and sort them Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190613084416.6794-2-jani.nikula@intel.com

- * dsl=0 ___/ |_____/ |

- * ^ ^ ^ ^ ^
- * | | | | pipe vblank/first part of tv vblank
- * | | | bottom margin
- * | | active
- * | top margin
- * remainder of tv vblank
- *
- * When the TV encoder is used the pipe wants to run faster
- * than expected rate. During the active portion the TV
- * encoder stalls the pipe every few lines to keep it in
- * check. When the TV encoder reaches the bottom margin the
- * pipe simply stops. Once we reach the TV vblank the pipe is
- * no longer stalled and it runs at the max rate (apparently
- * oversample clock on gen3, cdclk on gen4). Once the pipe
- * reaches the pipe vtotal the pipe stops for the remainder
- * of the TV vblank/top margin. The pipe starts up again when
- * the TV encoder exits the top margin.
- *
- * To avoid huge hassles for vblank timestamping we scale
- * the pipe timings as if the pipe always runs at the average
- * rate it maintains during the active period. This also
- * gives us a reasonable guesstimate as to the pixel rate.
- * Due to the variation in the actual pipe speed the scanline
- * counter will give us slightly erroneous results during the
- * TV vblank/margins. But since vtotal was selected such that
- * it matches the average rate of the pipe during the active
- * portion the error shouldn't cause any serious grief to
- * vblank timestamps.
- *
- * For posterity here is the empirically derived formula
- * that gives us the maximum length of the pipe vblank
- * we can use without causing display corruption. Following
- * this would allow us to have a ticking scanline counter
- * everywhere except during the bottom margin (there the
- * pipe always stops). Ie. this would eliminate the second
- * flat portion of the above graph. However this would also
- * complicate vblank timestamping as the pipe vtotal would
- * no longer match the average rate the pipe runs at during
- * the active portion. Hence following this formula seems
- * more trouble that it's worth.
