2019-08-23spi: spi-fsl-dspi: Exit the ISR with IRQ_NONE when it's not oursVladimir Oltean
The DSPI interrupt can be shared between two controllers at least on the LX2160A. In that case, the driver for one controller might misbehave and consume the other's interrupt. Fix this by actually checking if any of the bits in the status register have been asserted.

2019-08-20spi: spi-fsl-dspi: Move dspi_interrupt above dspi_transfer_one_messageVladimir Oltean
The two functions are loosely coupled through dspi->waitq, but logically, dspi_transfer_one_message depends on dspi_interrupt in order to complete. Move its definition above it so the I/O functions are grouped closer together.

2019-07-24spi: bcm2835: Fix 3-wire mode if DMA is enabledLukas Wunner
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.

2019-07-20dt-bindings: iio: ad7124: Fix dtc warnings in exampleRob Herring
With the conversion to DT schema, the examples are now compiled with dtc. The ad7124 binding example has the following warning: Documentation/devicetree/bindings/iio/adc/adi,ad7124.example.dts:19.11-21: \ Warning (reg_format): /example-0/adc@0:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1) There's a default #size-cells and #address-cells values of 1 for examples. For examples needing different values such as this one on a SPI bus, they need to provide a SPI bus parent node. Fixes: 26ae15e62d3c ("Convert AD7124 bindings documentation to YAML format.")
