From 9a852d44b26f8e60e2ae13df563824c0f8489135 Mon Sep 17 00:00:00 2001 From: Ray Jui Date: Thu, 10 Sep 2020 08:25:38 -0700 Subject: [PATCH] spi: bcm-qspi: Fix probe regression on iProc platforms iProc chips have QSPI controller that does not have the MSPI_REV offset. Reading from that offset will cause a bus error. Fix it by having MSPI_REV query disabled in the generic compatible string.
