-MIME-Version: 1.0

-From: Lukas Wunner <lukas@wunner.de>
-
-commit 8d8bef50365847134b51c1ec46786bc2873e4e47 upstream.
-
-Commit 6935224da248 ("spi: bcm2835: enable support of 3-wire mode")
-added 3-wire support to the BCM2835 SPI driver by setting the REN bit
-(Read Enable) in the CS register when receiving data. The REN bit puts
-the transmitter in high-impedance state. The driver recognizes that
-data is to be received by checking whether the rx_buf of a transfer is
-non-NULL.
-
-Commit 3ecd37edaa2a ("spi: bcm2835: enable dma modes for transfers
-meeting certain conditions") subsequently broke 3-wire support because
-it set the SPI_MASTER_MUST_RX flag which causes spi_map_msg() to replace
-rx_buf with a dummy buffer if it is NULL. As a result, rx_buf is
-*always* non-NULL if DMA is enabled.
-
-Reinstate 3-wire support by not only checking whether rx_buf is non-NULL,
-but also checking that it is not the dummy buffer.
-
