For this patch, coreboot commit b9a7877568cf ("rockchip/*: refactor edp
driver") introduces the related change to src/soc/rockchip/common/edp.c
renamed from .../rk3288/edp.c, which was introduced at coreboot commit
40f558e8f4f7 ("rockchip: support display").

The sign-offs are:

    $ git log b9a7877568cf -- src/soc/rockchip/{common,rk3288}/edp.c \
        | grep -i "Signed-off-by:" | sort -u

That file at that refactor-commit has two more fixes I'm interested in,
and it's not the only file things could be ported from. If I run the
above on a wider list of files upto current master I get 16 authors or
20 signoffs with duplicates (including e.g. original-signed-off-by),
most of them either @google.com, @chromium.org, or @rock-chips.com.

(There's also hdmi{.c,.h} licensed w/ GPL-2.0-or-later, and clock{.c,.h}
for which the U-Boot counterpart is already "GPL-2.0" assuming thats
GPL-2.0-only, so I've excluded both.)
