+Subject: dt-bindings: eeprom: at25: use "size" for FRAMs without device ID
+
+From: Markus Heidelberg <m.heidelberg@cab.de>
+
+commit 534c702c3c234665ca2fe426a9fbb12281e55d55 upstream.
+
+Not all FRAM chips have a device ID and implement the corresponding read
+command. Thus the memory size, which is contained in the device ID,
+cannot be detected and has to be set manually as it is done for EEPROMs.
