[PATCH v3 0/2] drm/i915/display: Power request asserting/deasserting

[PATCH v3 0/2] drm/i915/display: Power request asserting/deasserting

[Mika Kahola]

There is a HW issue that arises when there are race conditions
between TCSS entering/exiting TC7 or TC10 states while the
driver is asserting/deasserting TCSS power request. As a
workaround, Display driver will implement a mailbox sequence
to ensure that the TCSS is in TC0 when TCSS power request is
asserted/deasserted.

The sequence is the following

1. Read mailbox command status and wait until run/busy bit is
   clear
2. Write mailbox data value '1' for power request asserting
   and '0' for power request deasserting
3. Write mailbox command run/busy bit and command value with 0x1
4. Read mailbox command and wait until run/busy bit is clear
   before continuing power request.

while at it, let's start using struct intel_display instead of
struct drm_i915_private as well.

4. Read mailbox command and wait until run/busy bit is clear
   before continuing power request.

v2: Rename WA function (Gustavo)
    Limit WA only for PTL platform with a TODO note (Gustavo)
    Add TCSS_DISP_MAILBOX_IN_CMD_RUN_BUSY for clarity when writing
    register data (Gustavo)
    Move register defs from i915_reg.h to intel_cx0_phy_regs.h (Gustavo)
v3: use "struct intel_display" instead of "struct drm_i915_private" (Jani)
    Move defs above C10 definitions in the
    intel_cx0_phy_regs.h file (Gustavo)
    Move drm_WARN_ON() inside WA function (Gustavo)
    Rename workaround function as wa_14020908590() (Gustvo)
    Use boolean enable instead of if-else structure (Raag)

[PATCH v3 2/2] drm/i915/display: Use struct intel_display instead of struct drm_i915_private

[Mika Kahola]

Let's start using struct intel_display instead of struct drm_i915_private
when introducing new code. No functional changes.
