drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1

2018-10-29T15:53:28+00:00

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.

drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM

2018-10-29T15:53:27+00:00

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.

drm/panel: simple: Support panels with HPD where HPD isn't connected

2018-10-29T15:53:27+00:00

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.

If s6e8aa0_dcs_read() returns a negative error code, then "ret < ARRAY_SIZE(id)" is false because the negative error code is type promoted to a high positive value.
