The source BO updates the one that is currently not displayed and then switches buffers. Explicit BO locking has been removed from the code.

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.

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.
