2018-11-06drm/sun4i: tcon: fix check of tcon->panel null pointerGiulio Benetti
Since tcon->panel is a pointer returned by of_drm_find_panel() need to check if it is not NULL, hence a valid pointer. IS_ERR() instead checks return error values, not NULL pointers. Substitute "if (!IS_ERR(tcon->panel))" with "if (tcon->panel)".

2018-11-06drm/i915: Don't oops during modeset shutdown after lpe audio deinitVille Syrjälä
We deinit the lpe audio device before we call drm_atomic_helper_shutdown(), which means the platform device may already be gone when it comes time to shut down the crtc. As we don't know when the last reference to the platform device gets dropped by the audio driver we can't assume that the device and its data are still around when turning off the crtc. Mark the platform device as gone as soon as we do the audio deinit.

2018-11-05vga_switcheroo: Fix missing gpu_bound call at audio client registrationTakashi Iwai
The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for discrete GPU") added a new ops gpu_bound to be called when GPU gets bound. The patch overlooked, however, that vga_switcheroo_enable() is called only once at GPU is bound. When an audio client is registered after that point, it would miss the gpu_bound call. This leads to the unexpected lack of runtime PM in HD-audio side. For addressing that regression, just call gpu_bound callback manually at vga_switcheroo_register_audio_client() when the GPU was already bound.

This reverts commit 0586feba322e1de05075700eb4b835c8b683e62b This patch makes it to need get_vblank_counter callback in crtc to get frame counter from decon driver. However, drm_dev->max_vblank_count is a member unique to vendor's DRM driver but in case of ARM DRM, some CRTC devices don't provide the frame counter value. As a result, this patch made extension and clone mode not working. Instead of this patch, we may need separated max_vblank_count which belongs to each CRTC device, or need to implement frame counter emulation for them who don't support HW frame counter.

This patch here will do the same. Either driver or VBIOS can not pass 0 value as it is not a valid range for PWM and it will give a high PWM pulse which is not the intended behaviour as per HW constraints.

2018-10-29drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1Douglas Anderson
As far as I can tell the panel that was added in commit da50bd4258db ("drm/panel: simple: Add Innolux TV123WAM panel driver support") wasn't actually an Innolux TV123WAM but was actually an Innolux P120ZDG-BF1. As far as I can tell the Innolux TV123WAM isn't a real panel and but it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1. Let's unmosh. Here's my evidence: * Searching for TV123WAM on the Internet turns up a TI panel. While it's possible that an Innolux panel has the same model number as the TI Panel, it seems a little doubtful. Looking up the datasheet from the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm. * As far as I know, the patch adding the Innolux Panel was supposed to be for the board that's sitting in front of me as I type this (support for that board is not yet upstream). On the back of that panel I see Innolux P120ZDZ-EZ1 rev B1. * Someone pointed me at a datasheet that's supposed to be for the panel in front of me (sorry, I can't share the datasheet). That datasheet has the string "p120zdg-bf1" * If I search for "P120ZDG-BF1" on the Internet I get hits for panels that are 2160x1440. They don't have datasheets, but the fact that the resolution matches is a good sign. In any case, let's update the name and also the physical size to match the correct panel.

2018-10-29drm/bridge: ti-sn65dsi86: Remove the mystery delayDouglas Anderson
Let's solve the mystery of commit bf1178c98930 ("drm/bridge: ti-sn65dsi86: Add mystery delay to enable()"). Specifically the reason we needed that mystery delay is that we weren't paying attention to HPD. Looking at the datasheet for the same panel that was tested for the original commit, I see there's a timing "t3" that times from power on to the aux channel being operational. This time is specced as 0 - 200 ms. The datasheet says that the aux channel is operational at exactly the same time that HPD is asserted. Scoping the signals on this board showed that HPD was asserted 84 ms after power was asserted. That very closely matches the magic 70 ms delay that we had. ...and actually, in my testing the 70 ms wasn't quite enough of a delay and some percentage of the time the display didn't come up until I bumped it to 100 ms (presumably 84 ms would have worked too). To solve this, we tried to hook up the HPD signal in the bridge. ...but in doing so we found that that the bridge didn't report that HPD was asserted until ~280 ms after we powered it (!). This is explained by looking at the sn65dsi86 datasheet section "8.4.5.1 HPD (Hot Plug/Unplug Detection)". Reading there we see that the bridge isn't even intended to report HPD until 100 ms after it's asserted. ...but that would have left us at 184 ms. The extra 100 ms (presumably) comes from this part in the datasheet: > The HPD state machine operates off an internal ring oscillator. The > ring oscillator frequency will vary [ ... ]. The min/max range in > the HPD State Diagram refers to the possible times based off > variation in the ring oscillator frequency. Given that the 280 ms we'll end up delaying if we hook up HPD is _slower_ than the 200 ms we could just hardcode, for now we'll solve the problem by just hardcoding a 200 ms delay in the panel driver using the patch in this series ("drm/panel: simple: Support panels with HPD where HPD isn't connected"). If we later find a panel that needs to use this bridge where we need HPD then we'll have to come up with some new code to handle it. Given the silly debouncing in the bridge chip, though, it seems unlikely. One last note is that I tried to solve this through another way: In ti_sn_bridge_enable() I tried to use various combinations of dp_dpcd_writeb() and dp_dpcd_readb() to detect when the aux channel was up. In theory that would let me detect _exactly_ when I could continue and do link training. Unfortunately even if I did an aux transfer w/out waiting I couldn't see any errors. Possibly I could keep looping over link training until it came back with success, but that seemed a little overly hacky to me.

2018-10-29drm/panel: simple: Support panels with HPD where HPD isn't connectedDouglas Anderson
Some eDP panels that are designed to be always connected to a board use their HPD signal to signal that they've finished powering on and they're ready to be talked to. However, for various reasons it's possible that the HPD signal from the panel isn't actually hooked up. In the case where the HPD isn't hooked up you can look at the timing diagram on the panel datasheet and insert a delay for the maximum amount of time that the HPD might take to come up. Let's add support in simple-panel for this concept. At the moment we will co-opt the existing "prepare" delay to keep track of the delay and we'll use a boolean to specify that a given panel should only apply the delay if the "no-hpd" property was specified.
