Subject[PATCH v5 0/2] Lattice MachXO2 Slave SPI FPGA Manager support
Date
Hi all,                                                                                                                                                 

this series adds support for the Lattice MachXO2 FPGA chip, programmed
over Slave SPI.

Tested on my raspberry pi3 + bugblat's pif2 fpga hat.

Changes from v1:
* fixed all the warnings pointed out by 'checkpatch --strict' and
Alan Tull

Changes from v2:
* convert to BIT() macro and spi_message_init() / trans.delay_usecs

Changes from v3;
* loop unroll machxo2_write() and collate writes in a single spi_sync()

Changes from v4:

* rebased on 3.12
