2018-10-29drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1Douglas Anderson1-7/+7
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/panel: simple: Add "no-hpd" delay for Innolux TV123WAMDouglas Anderson1-0/+1
If the HPD signal isn't hooked up to this panel we need a 200 ms delay. In the datasheet this is shown as the maximum time that HPD will take to be asserted after power is given to the panel.

2018-10-29drm/panel: simple: Support panels with HPD where HPD isn't connectedDouglas Anderson1-2/+12
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.

Remove all drm_panel_detach() calls from all panel drivers and update the kerneldoc for drm_panel_detach(). Setting the connector and drm to NULL when the DRM panel device is going away hardly serves any purpose. Usually the whole memory structure is freed right after the remove call. However, calling the detach function from the master DRM device, and setting the connector pointer to NULL, has the logic of marking the panel again as available for another DRM master to attach.

Note that while include/linux/backlight.h provides a stub inline when backlight support is not enabled, this isn't enough to deal with the case where backlight support is built as a module but the panel driver is built-in, in which case linking will still fail as above. One way to avoid this is to add a dependency such as this: depends on BACKLIGHT_CLASS_DEVICE || BACKLIGHT_CLASS_DEVICE=n but that is rather complex and misses the point that the panel support is mostly useless without backlight support.

Convert the sharp lq123p1jx31 from using a fixed mode to specifying a display timing with min/typ/max values. This allows us to capture the timings set forth in the datasheet as well as the additional values that we've cleared with the display vendor to avoid interference with the digitizer on the Samsung Chromebook Plus (kevin). A follow-on patch will specify the override mode for kevin devices.

2018-02-07drm/panel: Add support for ARM Versatile panelsLinus Walleij3-0/+388
The ARM reference designs "Versatile AB" and "Versatile PB" contain panel connectors with autodetection of the connected panel type. This adds a small driver utilizing the MFD syscon look-up to read the autodetection register and set up the corresponding panel appropriately. In the source file there is a bit of elaboration of the panel types and interfaces on these boards. This was tested with the PL111 DRM driver on the ARM Versatile AB with the IB2 daughterboard.
