I copied the kerneldoc for encoder_funcs.atomic_enable from encoder_funcs.enable in a recent patch [1]. Sam rightly pointed out in the review that "for symmetry with" text is awkward [2]. So here's a patch to fix up the source of the awkward language.

On Rockchip rk3288-based Chromebooks when you do a suspend/resume cycle: 1. You lose the ability to detect an HDMI device being plugged in. 2. If you're using the i2c bus built in to dw_hdmi then it stops working. Let's call the core dw-hdmi's suspend/resume functions to restore things. NOTE: in downstream Chrome OS (based on kernel 3.14) we used the "late/early" versions of suspend/resume because we found that the VOP was sometimes resuming before dw_hdmi and then calling into us before we were fully resumed. For now I have gone back to the normal suspend/resume because I can't reproduce the problems. Signed-off-by:

On Rockchip rk3288-based Chromebooks when you do a suspend/resume cycle: 1. You lose the ability to detect an HDMI device being plugged in. 2. If you're using the i2c bus built in to dw_hdmi then it stops working. Let's add a hook to the core dw-hdmi driver so that we can call it in dw_hdmi-rockchip in the next commit. NOTE: the exact set of steps I've done here in resume come from looking at the normal dw_hdmi init sequence in upstream Linux plus the sequence that we did in downstream Chrome OS 3.14. Testing show that it seems to work, but if an extra step is needed or something here is not needed we could improve it. As part of this change we'll refactor the hardware init bits of dw-hdmi to happen all in one function and all at the same time. Since we need to init the interrupt mutes before we request the IRQ, this means moving the hardware init earlier in the function, but there should be no problems with that. Also as part of this we now unconditionally init the "i2c" parts of dw-hdmi, but again that ought to be fine. Signed-off-by:

All drivers add all their connectors so there's no need to keep around an array of available connectors. Instead we just put the useable (not writeback) connectors in a temporary array using drm_client_for_each_connector_iter() everytime we probe the outputs. Other places where it's necessary to look at the connectors, we just iterate over them using the same iterator function. Rename functions which signature is changed since they will be moved to drm_client in a later patch. v6: Improve commit message (Sam Ravnborg) Signed-off-by:

In commit 50f9495e ("drm/bridge/synopsys: dw-hdmi: Add "unwedge" for ddc bus") I stupidly used IS_ERR() to check for whether we have an "unwedge" pinctrl state even though on most flows through the driver the unwedge state will just be NULL.

This is an illegal scenario, to free the fence whilst there are pending callbacks. Currently, we emit a WARN and then cast aside the callbacks leaving them dangling. Alternatively, we could set an error on the fence and then signal fence so that any dependency chains from the fence can be tidied up, and if they care they can check for the error. Signed-off-by:
