MLK-19452-2 ARM: imx_v7_defconfig: Add spi slave mode
Add spi slave mode and enable spi slave time/system control
functions.
Example for SPI slave time:
SLAVE: # echo spi-slave-time > /sys/class/spi_slave/spi0/slave
MASTER: # spidev_test -D /dev/spidev0.0 -p dummy-8B -v
spi mode: 0x0
bits per word: 8
max speed: 500000 Hz (500 KHz)
RX | 00 00 04 6D 00 09 5B BB __ __ __ __ __ __ __ _...
^^^^^ ^^^^^^^^
seconds microseconds
Example for SPI slave system control:
SLAVE: # echo spi-slave-system-control >
/sys/class/spi_slave/spi0/slave
BOTH: # reboot='\x7c\x50'
BOTH: # poweroff='\x71\x3f'
BOTH: # halt='\x38\x76'
BOTH: # suspend='\x1b\x1b'
MASTER: # spidev_test -D /dev/spidev0.0 -p $suspend
or $reboot, $poweroff, $halt
