+Subject: [PATCH 167/171] BCM270X_DT: mz61581: Revert to spi-bcm2708
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The MZ61581 display does not work with spi-bcm2835 and software
+chip select. It works before the commit:
+spi: bcm2835: transform native-cs to gpio-cs on first spi_setup
+
+Revert to spi-bcm2708 until the cause has been detected and the
+issue resolved.
+
