Luca Ceresoli 16b7856d94 fpga manager: xilinx-spi: fix write_complete timeout handling ... If this routine sleeps because it was scheduled out, it might miss DONE going asserted and consider it a timeout. This would potentially make the code return an error even when programming succeeded. Rewrite the loop to always check DONE after checking if timeout expired so this cannot happen anymore. While there, also add error checking for gpiod_get_value(). Also avoid checking the DONE GPIO in two places, which would make the error-checking code duplicated and more annoying. The new loop it written to still guarantee that we apply 8 extra CCLK cycles after DONE has gone asserted, which is required by the hardware.
