This tablet display is unique and hence must be added to documentation. Unfortunately, it's real make and number is not known due to obscure and missing documentation and lack of writing on the display assembly itself. So the natural alternative that came to mind is to name the panel after the device that contained it (an Android tablet). Hopefully that isn't an issue. I can confirm that the parameters that I've obtained are correct since they came from a dump of the original Android OS. Signed-off-by:

dp-aux-bus.yaml says we can list an eDP panel as a child of an eDP controller node to represent the fact that the panel is connected to the controller's DP AUX bus. Let's add it to the ps8640 bindings. Signed-off-by:

The helper function devm_add_action_or_reset() will internally call devm_add_action(), and if devm_add_action() fails then it will execute the action mentioned and return the error code. So use devm_add_action_or_reset() instead of devm_add_action() to simplify the error handling, reduce the code. Signed-off-by:

Abstract the complexity of iterating over all the fences in a dma_resv object. The new loop handles the whole RCU and retry dance and returns only fences where we can be sure we grabbed the right one. v2: fix accessing the shared fences while they might be freed, improve kerneldoc, rename _cursor to _iter, add dma_resv_iter_is_exclusive, add dma_resv_iter_begin/end v3: restructor the code, move rcu_read_lock()/unlock() into the iterator, add dma_resv_iter_is_restarted() v4: fix NULL deref when no explicit fence exists, drop superflous rcu_read_lock()/unlock() calls. v5: fix typos in the documentation v6: fix coding error when excl fence is NULL v7: one more logic fix v8: fix index check in dma_resv_iter_is_exclusive() Signed-off-by: -

In the commit bac9c294 ("drm/edid: Break out reading block 0 of the EDID") I broke out reading the base block of the EDID to its own function. Unfortunately, when I did that I messed up the handling when drm_edid_is_zero() indicated that we had an EDID that was all 0x00 or when we went through 4 loops and didn't get a valid EDID. Specifically I needed to pass the broken EDID to connector_bad_edid() but now I was passing an error-pointer. Let's re-jigger things so we can pass the bad EDID in properly.
