[PATCH 0/2] drm/panel: samsung: Share test key command helpers

[Linus Walleij <linusw@kernel.org>]

Several Samsung display controller drivers use identical three-byte
commands to enable and disable test key levels. The commands are
currently repeated as driver-specific macros or raw DCS writes.

Add a private Samsung DSI header with typed helpers for all three test
key levels. Use it in the drivers that already identify these commands
by level, including the S6E88A0 AMS452EF01 driver whose comments identify
the raw F0 pair as level 2 commands.

Drivers with conflicting level numbering or without an established
test-key name are deliberately left unchanged.
