It replaces dc3co_enabled with dc3co_exitline on intel_psr struct. And it saves dc3co_exitline, not dc3co_enabled, so we can use dc3co_exitline without intel_crtc_state on other psr internal function like as intel_psr_enable_source().

2021-05-19drm/i915/adl_p: Tx escape clock with DSIMika Kahola
Today when the DSI controller is paired with the Combo-PHY it uses the high-speed (HS) Word clock for its low power (LP) transmit PPI communication to the DPHY. The interface signaling only changes state at an Escape clock frequency (i.e. its effectively running on a virtual Tx Escape clock that is controlled by counters w/in the controller), but all the interface flops are running off the HS clock. This has the following drawbacks: * It is a deviation from the PPI spec which assumes signaling is running on a physical Escape clock * The PV timings are over constrained (HS timed to 312.5MHz vs. an Escape clock of 20MHz max) This feature is proposing to change the LP Tx communication between the controller and the DPHY from a virtual Tx Escape clock to a physical clock. To do this we need to program two "M" divisors. One for the usual DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV register and one for MIPIO_DWORD8. For DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV registers the "M" is calculated as following Nt = ceil(f_link/160) (theoretical word clock) Nact = max[3, Nt + (Nt + 1)%2] (actual word clock) M = Nact * 8 For MIPIO_DWORD8 register, the divisor "M" is calculated as following M = (Nact - 1)/2 BSpec: 55171 Cc: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Clinton Taylor <Clinton.A.Taylor@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Vandita Kulkarni <vandita.kulkarni@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210519000625.3184321-11-lucas.demarchi@intel.com

2021-05-19drm/i915: Introduce MBUS relative dbuf offsetsVille Syrjälä
The dbuf slices are going to be split across several MBUS units. The actual dbuf programming will use offsets relative to the MBUS unit. To accommodate that we shall store the MBUS relative offsets into the dbuf_state->ddb[] and crtc_state->plane_ddb*[]. For crtc_state->wm.skl.ddb however we want to stick to global offsets as we use this to sanity check that the ddb allocations don't overlap between pipes.

2021-05-14drm/i915/adl_p: Add cdclk support for ADL-PAnusha Srivatsa
ADL-P has 3 possible refclk frequencies: 19.2MHz, 24MHz and 38.4MHz While we're at it, remove the drm_WARNs. They've never actually helped us catch any problems, but it's very easy to forget to update them properly for new platforms.

2021-05-14drm/i915/adl_p: Extend PLANE_WM bits for blocks & linesMatt Roper
ADL-P further extends the bits in PLANE_WM that represent blocks and lines; we need to extend our masks accordingly. Since these bits are reserved and MBZ on earlier platforms, it's safe to use the larger bitmask on all platforms.

2021-05-14drm/i915/xelpd: Increase maximum watermark lines to 255Matt Roper
XE_LPD continues to use the same "skylake-style" watermark programming as other recent platforms. The only change to the watermark calculations compared to Display12 is that XE_LPD now allows a maximum of 255 lines vs the old limit of 31. Due to the larger possible lines value, the corresponding bits representing the value in PLANE_WM are also extended, so make sure we read/write enough bits. Let's also take this opportunity to switch over to the REG_FIELD notation.

2021-05-14drm/i915/xelpd: Handle new location of outputs D and EMatt Roper
The DDI naming template for display version 12 went A-C, TC1-TC6. With XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4. The XE_LPD design keeps the register offsets and bitfields relating to the TC outputs in the same location they were previously. The new "D" and "E" outputs now take the locations that were previously used by TC5 and TC6 outputs, or what we would have considered to be outputs "H" and "I" under the legacy lettering scheme. For the most part everything will just work as long as we initialize the output with the proper 'enum port' value. However we do need to take care to pick the correct AUX channel when parsing the VBT (e.g., a reference to 'AUX D' is actually asking us to use the 8th aux channel, not the fourth). We should also make sure that our encoders and aux channels are named appropriately so that it's easier to correlate driver debug messages with the bspec instructions. v2: - Update handling of TGL_TRANS_CLK_SEL_PORT. (Jose) v3: - Add hpd_pin to handle outputs D and E (Jose) - Fixed conversion of BIOS port to aux ch for TC ports (Jose) Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210514153711.2359617-2-matthew.d.roper@intel.com
