Subject: [PATCH] spi: xtensa-xtfpga: fix register endianness
Date: Tue, 22 Sep 2015 14:32:03 +0300 [thread overview]
Message-ID: <1442921523-1265-1-git-send-email-jcmvbkbc@gmail.com> (raw)
XTFPGA SPI controller has native endian registers.
Fix register acessors so that they work in big-endian configurations.
