[Intel-gfx] [PATCH v2 00/13] drm/i915/mtl: Add support for C20 phy

[Mika Kahola]

Add support for C20 phy for Type-C connections. C20 phy differs from
C10 and hence we need to separately handle this case.

v2: Fixes for C20 pll programming and hw readout

[Intel-gfx] [PATCH v2 01/13] drm/i915/mtl: C20 PLL programming

[Mika Kahola]

C20 phy PLL programming sequence for DP, DP2.0, HDMI2.x non-FRL and
HDMI2.x FRL. This enables C20 MPLLA and MPLLB programming sequence. add
4 lane support for c20.

v2: Add 6.48Gbps and 6.75Gbps modes for eDP (RK)
    Fix lane check (RK)
    Fix multiline commenting (Arun)
    use usleep_range() instead of msleep() (Andi)

[Intel-gfx] [PATCH v2 02/13] drm/i915/mtl: C20 HW readout

[Mika Kahola]

Create a table for C20 DP1.4, DP2.0 and HDMI2.1 rates.
The PLL settings are based on table, not for algorithmic alternative.
For DP 1.4 only MPLLB is in use.

Once register settings are done, we read back C20 HW state.

BSpec: 64568

v2: Updated pll tables (RK)
    MPLLB selection fix (RK)

[Intel-gfx] [PATCH v2 09/13] drm/i915/mtl: Define mask for DDI AUX interrupts

[Mika Kahola]

From: Gustavo Sousa <gustavo.sousa@intel.com>

Xe_LPD+ defines interrupt bits for only DDI ports in the DE Port
Interrupt registers. The bits for Type-C ports are defined in the PICA
interrupt registers.

[Intel-gfx] [PATCH v2 10/13] drm/i915/mtl: Power up TCSS

[Mika Kahola]

Add register writes to enable powering up Type-C subsystem i.e. TCSS.
For MeteorLake we need to request TCSS to power up and check the TCSS
power state after 500 us.

In addition, for PICA we need to set/clear the Type-C PHY ownnership
bit when Type-C device is connected/disconnected.

[Intel-gfx] [PATCH v2 11/13] drm/i915/mtl: TypeC HPD live status query

[Mika Kahola]

From: Imre Deak <imre.deak@intel.com>

The HPD live status for MTL has to be read from different set of
registers. MTL deserves a new function for this purpose
and cannot reuse the existing  HPD live status detection

[Intel-gfx] [PATCH v2 12/13] drm/i915/mtl: Pin assignment for TypeC

[Mika Kahola]

From: Anusha Srivatsa <anusha.srivatsa@intel.com>

Unlike previous platforms that used PORT_TX_DFLEXDPSP
for max_lane calculation, MTL uses only PORT_TX_DFLEXPA1
from which the max_lanes has to be calculated.
