2020-07-02drm/i915/display: prefer dig_port to reference intel_digital_portLucas De Marchi1-4/+4
We have a mix of dport, intel_dport, intel_dig_port and dig_port to reference a intel_digital_port struct. Numbers are around 5 intel_dport 36 dport 479 intel_dig_port 352 dig_port Since we already removed the intel_ prefix from most of our other structs, do the same here and prefer dig_port. v2: rename everything in i915, not just a few display sources and reword commit message (from Matt Roper) Signed-off-by: Lucas De Marchi <[email protected]> Reviewed-by: Rodrigo Vivi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2020-05-20drm/i915/rkl: Add power well supportMatt Roper1-2/+2
RKL power wells are similar to TGL power wells, but have some important differences: * PG1 now has pipe A's VDSC (rather than sticking it in PG2) * PG2 no longer exists * DDI-C (aka TC-1) moves from PG1 -> PG3 * PG5 no longer exists due to the lack of a fourth pipe Also note that what we refer to as 'DDI-C' and 'DDI-D' need to actually be programmed as TC-1 and TC-2 even though this platform doesn't have TC outputs.

Converts uses of the printk based drm logging macros to the new struct drm_device based logging macros in i915/display/intel_vdsc.c.

2019-12-19drm/i915/dsc: fix DSC power domains for DSIJani Nikula1-13/+15
Fix several issues with DSC power domains that did not take DSI transcoders into account: - On TGL+ we need to use PW2 for DSC on pipe A, not transcoder A. There is no longer an eDP transcoder, but there are two DSI transcoders which may be connected to pipe A. - On TGL+ we need to use the pipe, not transcoder, power domains for DSC on pipes other than A. Again, there are DSI transcoders. - On ICL we need to use PW2 for DSC also for DSI transcoders, not just for the eDP transcoder. Using is_pipe_dsc() also adds the warning about ICL pipe A DSC, which does not exist.
