If anyone has any objections, please let me know. ------------------ From: Douglas Anderson [ Upstream commit 749b5b279e5636cdcef51e15d67b77162cca6caa ] We have a few reports of sc7180-trogdor-pompom devices that have a panel in them that IDs as STA 0x0004 and has the following raw EDID: 00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00 10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28 1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20 55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe 00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6 We've been unable to locate a datasheet for this panel and our partner has not been responsive, but all Starry eDP datasheets that we can find agree on the same timing (delay_100_500_e200) so it should be safe to use that here instead of the super conservative timings. We'll still go a little extra conservative and allow `hpd_absent` of 200 instead of 100 because that won't add any real-world delay in most cases. We'll associate the string from the EDID ("116KHD024006") with this panel. Given that the ID is the suspicious value of 0x0004 it seems likely that Starry doesn't always update their IDs but the string will still work to differentiate if we ever need to in the future.
