From 5b32b1368ae532a2d06c931ba6356c39a9de63ac Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Mon, 28 Sep 2015 19:51:18 +0300 Subject: [PATCH] memory: pl172: correct MPMC peripheral ID register bits According to PL172 TRM read of bits [7:6] of MPMCPeriphID3 is undefined, so unmask them. Also the driver supports all currently present revisions of PL172, this allows to alleviate requirements to the revision version matched by the driver.
