Hi Bruce,
When userspace program try to initialize full duplex SPI transaction
through ioctl system call to SPIDEV driver, SPIDEV driver return
"invalid argument" to userspace program.
There are 4 patches modify the size of the structure used by SPIDEV
driver and this revert is fix the issue introduced by 4 of the
patches.
950a0f4 spi: modify spidev_test to test modifying FIFO trigger level
during runtime
db6b515 spi/pxa2xx: Add new ioctl for configuring FIFO trigger level
in runtime
c455485 spi: modify spidev_test to test automatic PIO/DMA switching
afe9c4b spi/pxa2xx: auto switch between PIO and DMA with
configurable threshold size
These patches are targeted for linux-yocto-3.14 kernel
standard/valleyisland branch.
Kindly review the patches and merge if there is no issue.
Thank you.
Regards,
Chai, Chong Yi
