Subject: [PATCH v2 0/3] xtensa xtfpga SPI controller driver
Date: Wed, 12 Mar 2014 16:21:02 +0400 [thread overview]
Message-ID: <1394626865-15105-1-git-send-email-jcmvbkbc@gmail.com> (raw)
Hello,
this series adds driver for SPI controller used on xtfpga xtensa platform,
device tree binding documentation and an entry to MAINTAINERS.
Changes v1 -> v2:
- support 8 bit transfers;
- busy-wait for maximum 100 usec (instead of 100 msec) polling BUSY register;
- use chipselect callback to check transfer size.
