+ * intel_update_watermarks - update FIFO watermark values based on current modes
+ * @dev_priv: i915 device
+ *
+ * Calculate watermark values for the various WM regs based on current mode
+ * and plane configuration.
+ *
+ * There are several cases to deal with here:
+ *   - normal (i.e. non-self-refresh)
+ *   - self-refresh (SR) mode
+ *   - lines are large relative to FIFO size (buffer can hold up to 2)
+ *   - lines are small relative to FIFO size (buffer can hold more than 2
+ *     lines), so need to account for TLB latency
+ *
+ *   The normal calculation is:
+ *     watermark = dotclock * bytes per pixel * latency
+ *   where latency is platform & configuration dependent (we assume pessimal
+ *   values here).
+ *
+ *   The SR calculation is:
+ *     watermark = (trunc(latency/line time)+1) * surface width *
+ *       bytes per pixel
+ *   where
+ *     line time = htotal / dotclock
+ *     surface width = hdisplay for normal plane and 64 for cursor
+ *   and latency is assumed to be high, as above.
+ *
+ * The final value programmed to the register should always be rounded up,
+ * and include an extra 2 entries to account for clock crossings.
+ *
+ * We don't use the sprite, so we can ignore that.  And on Crestline we have
+ * to set the non-SR watermarks to 8.

-/**
- * DOC: Display Refresh Rate Switching (DRRS)
- *
- * Display Refresh Rate Switching (DRRS) is a power conservation feature
- * which enables swtching between low and high refresh rates,
- * dynamically, based on the usage scenario. This feature is applicable
- * for internal panels.
- *
- * Indication that the panel supports DRRS is given by the panel EDID, which
- * would list multiple refresh rates for one resolution.
- *
- * DRRS is of 2 types - static and seamless.
- * Static DRRS involves changing refresh rate (RR) by doing a full modeset
- * (may appear as a blink on screen) and is used in dock-undock scenario.
- * Seamless DRRS involves changing RR without any visual effect to the user
- * and can be used during normal system usage. This is done by programming
- * certain registers.
- *
- * Support for static/seamless DRRS may be indicated in the VBT based on
- * inputs from the panel spec.
- *
- * DRRS saves power by switching to low RR based on usage scenarios.
- *
- * The implementation is based on frontbuffer tracking implementation.  When
- * there is a disturbance on the screen triggered by user activity or a periodic
- * system activity, DRRS is disabled (RR is changed to high RR).  When there is
- * no movement on screen, after a timeout of 1 second, a switch to low RR is
- * made.
- *
- * For integration with frontbuffer tracking code, intel_edp_drrs_invalidate()
- * and intel_edp_drrs_flush() are called.
- *
- * DRRS can be further extended to support other internal panels and also
- * the scenario of video playback wherein RR is set based on the rate
- * requested by userspace.

+/**
+ * DOC: Display Refresh Rate Switching (DRRS)
+ *
+ * Display Refresh Rate Switching (DRRS) is a power conservation feature
+ * which enables swtching between low and high refresh rates,
+ * dynamically, based on the usage scenario. This feature is applicable
+ * for internal panels.
+ *
+ * Indication that the panel supports DRRS is given by the panel EDID, which
+ * would list multiple refresh rates for one resolution.
+ *
+ * DRRS is of 2 types - static and seamless.
+ * Static DRRS involves changing refresh rate (RR) by doing a full modeset
+ * (may appear as a blink on screen) and is used in dock-undock scenario.
+ * Seamless DRRS involves changing RR without any visual effect to the user
+ * and can be used during normal system usage. This is done by programming
+ * certain registers.
+ *
+ * Support for static/seamless DRRS may be indicated in the VBT based on
+ * inputs from the panel spec.
+ *
+ * DRRS saves power by switching to low RR based on usage scenarios.
+ *
+ * The implementation is based on frontbuffer tracking implementation.  When
+ * there is a disturbance on the screen triggered by user activity or a periodic
+ * system activity, DRRS is disabled (RR is changed to high RR).  When there is
+ * no movement on screen, after a timeout of 1 second, a switch to low RR is
+ * made.
+ *
+ * For integration with frontbuffer tracking code, intel_drrs_invalidate()
+ * and intel_drrs_flush() are called.
+ *
+ * DRRS can be further extended to support other internal panels and also
+ * the scenario of video playback wherein RR is set based on the rate
+ * requested by userspace.

- * Disconnect the given digital port from its TypeC PHY (handing back the

- * function is to force the disconnect even with a TypeC display output still
- * plugged to the TypeC connector, which is required by the TypeC firmwares
- * during system suspend and shutdown. Otherwise - during the unplug event
- * handling - the PHY ownership is released automatically by
- * intel_tc_port_reset_mode(), when calling this function is not required.
+ * Flush the delayed work disconnecting an idle PHY.

-/**
- * intel_update_watermarks - update FIFO watermark values based on current modes
- * @crtc: the #intel_crtc on which to compute the WM
- *
- * Calculate watermark values for the various WM regs based on current mode
- * and plane configuration.
- *
- * There are several cases to deal with here:
- *   - normal (i.e. non-self-refresh)
- *   - self-refresh (SR) mode
- *   - lines are large relative to FIFO size (buffer can hold up to 2)
- *   - lines are small relative to FIFO size (buffer can hold more than 2
- *     lines), so need to account for TLB latency
- *
- *   The normal calculation is:
- *     watermark = dotclock * bytes per pixel * latency
- *   where latency is platform & configuration dependent (we assume pessimal
- *   values here).
- *
- *   The SR calculation is:
- *     watermark = (trunc(latency/line time)+1) * surface width *
- *       bytes per pixel
- *   where
- *     line time = htotal / dotclock
- *     surface width = hdisplay for normal plane and 64 for cursor
- *   and latency is assumed to be high, as above.
- *
- * The final value programmed to the register should always be rounded up,
- * and include an extra 2 entries to account for clock crossings.
- *
- * We don't use the sprite, so we can ignore that.  And on Crestline we have
- * to set the non-SR watermarks to 8.
