Subject[PATCH v3 0/3] xtensa xtfpga SPI controller driver
Date
Hello,

this series adds driver for SPI controller used on xtfpga xtensa platform,
device tree binding documentation and an entry to MAINTAINERS.

Changes v2 -> v3:
- support all transfer widths in the range 1...16 bit;
- don't swap bytes of 16 bit transfers.

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.
