As the other restrictions from V1 are still valid, I better repeat them
here:
- one fat patch for now. I hope I can split it up, later, if needed.
- not yet checkpatch clean, will clean up when all the functionality
works (mostly 80 char-issues)
- the clock-name for clk_get is hardcoded for now. Will be adapted to
the reworked clock-framework when available.
- DMA is just selectable for MX1 and untested.
- If you can comment on the "XXX"-marked issue, please do
- ATTENTION: The original FSL-driver has a bug regarding the polarity
CPOL which got flipped. So, if you used the FSL-driver before, then
the SPI_MODE of your spi_device has to be corrected. Just toggle
SPI_CPOL or make SPI_MODE_0 out of SPI_MODE_2, SPI_MODE_1 out of
SPI_MODE_3 or vice versa.
Regards,
Wolfram
