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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
