2023-11-17drm/i915: convert vlv_dpio_read()/write() from pipe to phyJani Nikula1-3/+3
vlv_dpio_read() and vlv_dpio_write() really operate on the phy, not pipe. Passing the pipe instead of the phy as parameter is supposed to be a convenience, but when the caller has the phy, it becomes an inconvenience. See e.g. chv_dpio_cmn_power_well_enable() and assert_chv_phy_powergate(). Figure out the phy in the callers, and pass phy to the dpio functions. v2: retract one overzealous pipe->phy change (Ville) 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/20231114104534.4180144-3-jani.nikula@intel.com
2022-01-10drm/i915: split out vlv sideband registers from i915_reg.hJani Nikula1-0/+2
Add a dedicated file vlv_sideband_reg.h for the VLV/CHV sideband registers. The sideband registers macros are needed by the same files that need vlv_sideband.h, so include the definitions from there. v2: Fix copyright year (Matt) Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220110095740.166078-2-jani.nikula@intel.com
2021-10-14drm/i915: split out vlv sideband to a separate fileJani Nikula1-0/+123
The VLV/CHV sideband code is pretty distinct from the rest of the sideband code. Split it out to new vlv_sideband.[ch]. Pure code movement with relevant #include changes, and a tiny checkpatch fix on top.
