054320b25 spi: clps711x: Convert to use CS GPIO descriptors ... Browse Code »

This converts the CLPS711x SPI master driver to use GPIO
descriptors for chip select handling.

The CLPS711x driver was merely requesting the GPIO and
setting the CS line non-asserted so this was a pretty
straight-forward conversion. The setup callback goes away.

In the implementation of __spi_validate(), spi core will set transfer
bits_per_word and max speed as spi device default if it is not set for
this transfer. So we can remove the same logic in spi_clps711x_setup_xfer() and
spi_clps711x_transfer_one().

Thus, it is not needed to manually clear the device driver data to NULL.

766ed7044 spi: remove check for bits_per_word on transfer from low level driver ... Browse Code »

The spi core make sure that each transfer structure have the proper
setting for bits_per_word before calling low level transfer APIs.

Hence it is no more require to check again in low level driver for
this field whether this is set correct or not. Removing such code
from low level driver.

The txx9 change also removes a test for bits_per_word set to 0, and
forcing it to 8 in that case. This can also be removed now since
spi_setup() ensures spi->bits_per_word is not zero.

if (!spi->bits_per_word)
spi->bits_per_word = 8;
