Starting on CNL we now need to map VBT DDC Pin to BSPec DDC Pin values. Not a direct translation anymore. According to VBT Block 2 (General Bytes Definition) DDC Bus +----------+-----------+--------------------+ | DDI Type | VBT Value | Bspec Mapped Value | +----------+-----------+--------------------+ | DDI-B | 0x1 | 0x1 | | DDI-C | 0x2 | 0x2 | | DDI-D | 0x3 | 0x4 | | DDI-F | 0x4 | 0x3 | +----------+-----------+--------------------+ v2: Move defines to a better place. This is actually CNL_PCH not CNL only. v3: Accepting Ville's suggestions: enums and array to to make this future proof. v4: Protect the array access as Ville suggested. Also accepting all Jani's suggestions: - use already defined gmbus pin definitions. - use map_ddc_pin for disambiguation. - Add /* sic */ comment on inverted values so people can easily see it it nos a mistake we have the map 3 -> 4 and 4 -> 3 :/ Cc: Jani Nikula <jani.nikula@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Clinton Taylor <clinton.a.taylor@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by:

This patch parse DSI backlight/cabc ports info from VBT and save them inside local structure. This saved info can be directly used while initializing DSI for different platforms instead of parsing for each platform. V2: Changes: - Typo fix in commit message. - Move up newly added port variables (Jani N) - Remove redundant initialization (Jani N) - Don't parse CABC ports if not supported (Jani N) V3: Patch restructure (Suggested by Jani N) Credits-to: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

Handle missing buf trans tables, or out of bounds buf trans levels the same way everywhere. These should never be hit under normal conditions, but let's play it safe for now. v2: Avoid the hdmi_level=-1 case (James) Cc: James Ausmus <james.ausmus@intel.com> Signed-off-by:

Ville Syrjälä authored
SKL DDI B/C/D only have 9 usable buf trans registers for DP/eDP. That matches the normal DP buf trans tables, but the low vswing eDP tables have 10 entries. Thus the eDP tables can only be used safely with DDI A and E. We try to catch cases where DDI B/C/D gets used with the wrong number of entires in some parts of the code, but not everywhere. Let's move the code to deal with that deeper into intel_ddi_get_buf_trans_edp(). And for sake of symmetry do the same in intel_ddi_get_buf_trans_dp(). That would also avoid explosions in the rather unlikely case that the DP tables would get revised to 10 entries as well. Signed-off-by:

Ville Syrjälä authored
default_index contained in the BXT buf_trans tables is actually useless. For DP we should always have a valid level selected (otherwise the link training logic would be buggy), and for HDMI we can just do what the other platforms do and pick the correct entry in intel_ddi_hdmi_level().

Now that the infoframe hooks are part of the intel_dig_port, we can use the normal .write_infoframe() hook to update the VSC SDP. We do need to deal with the size difference between the VSC DIP and the others though. Another minor snag is that the compiler will complain to use if we keep using enum hdmi_infoframe_type type and passing in the DP define instead, so et's just change to unsigned int all over for the inforframe type. v2: Rebase due to other PSR changes Reviewed-by:

HDMI Mode selection on CNL is on CFGCR0 for that PLL, not on in a global CTRL1 as it was on SKL. The original patch addressed this difference, but leaving behind this single entry here. So we were checking the wrong bits during the PLL initialization and consequently avoiding the CFGCR1 setup during HDMI initialization. Luckly when only HDMI was in use BIOS had already setup this for us. But the dual display with hot plug were messed up.

On PLL Enable sequence we need to "Configure DPCLKA_CFGCR0 to turn on the clock for the DDI and map the DPLL to the DDI" So we first do the map and then we unset DDI_CLK_OFF to turn the clock on. We do this in 2 separated steps. However, on this second step where we should only unset the off bit we are also unmapping the ddi from the pll. So we end up using the pll 0 for almost everything. Consequently breaking cases with more than one display.
