Subject: [PATCH 0/5] fpga: ts73xx and iCE40 support

Hi Greg,

Please take these patches that add FPGA suppport
for ts73xx and iCE0 FPGAs.  I've done small fixups.

drivers/fpga/ice40-spi.c:
 fix printf format s/%ld/%d/ in 2 places

drivers/fpga/ts73xx-fpga.c:
 remove error message in probe. 

More details on the fixups:
