Subject: [PATCH 8/8] ARM: tqma6ul: use upstream device trees
Date: Wed, 21 Feb 2024 16:03:23 +0100	[thread overview]
Message-ID: <20240221150323.2715164-9-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20240221150323.2715164-1-s.hauer@pengutronix.de>

The tqma6ul has several upstream device trees depending on the exact
board type. This removes the downstream device tree in favour for the
upstream device trees. The board type can be determined from an EEPROM
on the board. This patch also adds support for reading the EEPROM and
picking the right device tree for the board found.

The EEPROM has the board described as strings. I do not know the correct
strings for the boards I don't have, so right now only the device tree
for the "TQMa6UL2L-AB.0202" board is picked. A warning is printed when
an unknown board type is found, so this can be added as new board type
when found.
