So if we want to transmit data in non-continuous clock mode to reduce power consumption, then host driver should set DSIM_CLKLANE_STOP bit. In this case, host controller turns off HS clock between high speed transmissions. For this, this patch adds a new bit, DSIM_CLKLANE_STOP, and makes the host driver sets this bit only in case that dsi->mode_flags has MIPI_DSI_CLOCK_NON_CONTINUOUS flag.

All host drivers shall support continuous clock behavior on the Clock Lane, and optionally may support non-continuous clock behavior. Both of them can transmit data in high speed of low power. With each clock behavior, non-continuous or continuous clock mode, host controller will transmit data in high speed by default so if peripheral wants to receive data in low power, the peripheral driver should set MIPI_DSI_MODE_LPM flag.

However, this leaves the pending pageflip still stuck indefinitely.

This annoyed people who relied on their systems being able to display continuously updating information 24/7, and so some code to detect when the driver missed the page flip completion signal was added. Until recently, it was presumed that the interrupt handling was now flawless, but once again Simon Farnsworth has found a system whose display will stall. Reinstate the pageflip stall detection, which works by checking to see if the hardware has been updated to the new framebuffer address following each vblank. If the hardware is scanning out from the new framebuffer, but we still think the flip is pending, then we kick our driver into submision. This is a continuation of the effort started with commit 4e5359cd053bfb7d8dabe4a63624a5726848ffbc Author: Simon Farnsworth <simon.farnsworth@onelan.co.uk> Date: Wed Sep 1 17:47:52 2010 +0100 drm/i915: Avoid pageflipping freeze when we miss the flip prepare interrupt This now includes a belt-and-braces approach to make sure the driver (or the hardware) doesn't miss an interrupt and cause us to stop updating the display should the unthinkable happen and the pageflip fail - i.e. that the user is able to continue submitting flips. v2: Cleanup, refactor, and rename v3: Only start counting vblanks after the flip command has been seen by the hardware. v4: Record the seqno after we touch the ring, or else there may be no seqno allocated yet. v5: Rebase on mmio-flip. v6: Rebase, rebase.

This also matches the BSpec modeset sequence better. We still don't match the spec exactly though (eg. audio disable should happen much earlier), but at last this eliminates the nasty wait_for_pipe_off() timeouts. We already did the port disable after the pipe for VLV/CHV and for CPU eDP. For g4x leave the port disable where it is since that matches the modeset sequence in the documentation and I don't have a suitable machine to test if the other order would work.

So turn on panel power (part of the "kick") before aux transfers (DPMS_ON + link training). This also matches the documented modeset sequence better for pch platforms. The documentation doesn't explicitly state anything about the DPMS or link training DPCD writes, but the panel power on step is always listed before link training is mentioned.
