[PATCH v2 2/6] spi: sun4i: restrict transfer length in PIO-mode

2018-04-03 Thread Sergey Suloev
There is no need to handle the 3/4 FIFO empty interrupt as the maximum supported transfer length in PIO mode is 64 bytes. As long as a problem was reported previously with filling FIFO on A10s we want to stick with 63 bytes depth. Changes in v2: 1) Restored processing of 3/4 FIFO full interrupt.
