* | spi: Add an helper to flush the message queue | Boris Brezillon | 2018-04-23 | 1 | -0/+2 |
| | | | | | | | | | | This is needed by the spi-mem logic to force all messages that have been queued before a memory operation to be sent before we start the memory operation. We do that in order to guarantee that spi-mem operations do not preempt regular SPI transfers.

* | spi: Expose spi_{map,unmap}_buf() for internal use | Boris Brezillon | 2018-04-23 | 1 | -0/+41 |
spi_{map,unmap}_buf() are needed by the spi-mem logic that is about to be introduced to prepare data buffer for DMA operations. Remove the static specifier on these functions and add their prototypes to drivers/spi/internals.h. We do not export the symbols here because both SPI_MEM and SPI can't be enabled as modules and we'd like to prevent controller/device drivers from using these functions.
