When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because there is no need to check these functions, a number of local functions can be made to return void to simplify things as nothing can fail.

The cursor handling in mgag200 is complicated to understand. It touches a number of different BOs, but doesn't really use all of them. Rewriting the cursor update reduces the amount of cursor state. There are two BOs for double-buffered HW updates. The source BO updates the one that is currently not displayed and then switches buffers. Explicit BO locking has been removed from the code. BOs are simply pinned and unpinned in video RAM. v2: * pin cursor BOs to current location Signed-off-by:

Another explicit lock operation of a GEM VRAM BO is located in mgag200's framebuffer update code. Instead of locking the BO, we pin it to wherever it is. v2: * update with pin flag of 0 Signed-off-by:

The ast driver used to lock the cursor source BO during updates. Locking should be done internally by the BO's implementation, so we pin it instead to system memory. The mapping information is also stored in the BO. No need to have an extra argument to the kmap function. v2: * pin cursor BOs to current location Signed-off-by:

The ast driver's data structures store unused or uncecessary cursor state. Most of the cursor state is already stored elsewhere and can be retrieved when necessary. Remove the obsolete fields and adapt users accordingly. Signed-off-by:

Pinning a buffer prevents it from being moved to a different memory location. For some operations, such as buffer updates, it is not important where the buffer is located. Setting the pin function's pl_flag argument to 0 will pin the buffer to whereever it is stored. v2: * document pin flags in PRIME pin helper Signed-off-by:

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:
