/**
|

|
|
* struct plat_max3100 - MAX3100 SPI UART platform data
|
||
|
|
* @loopback: force MAX3100 in loopback
|
||
|
|
* @crystal: 1 for 3.6864 Mhz, 0 for 1.8432
|
||
|
|
* @max3100_hw_suspend: MAX3100 has a shutdown pin. This is a hook
|
||
|
|
* called on suspend and resume to activate it.
|
||
|
|
* @poll_time: poll time for CTS signal in ms, 0 disables (so no hw
|
||
|
|
* flow ctrl is possible but you have less CPU usage)
|
||
|
|
*
|
||
|
|
* You should use this structure in your machine description to specify
|
||
|
|
* how the MAX3100 is connected. Example:
|
||
|
|
*
|
||
|
|
* static struct plat_max3100 max3100_plat_data = {
|
||
|
|
* .loopback = 0,
|
||
|
|
* .crystal = 0,
|
||
|
|
* .poll_time = 100,
|
||
|
|
* };
|
||
|
|
*
|
||
|
|
* static struct spi_board_info spi_board_info[] = {
|
||
|
|
* {
|
||
|
|
* .modalias = "max3100",
|
||
|
|
* .platform_data = &max3100_plat_data,
|
||
|
|
* .irq = IRQ_EINT12,
|
||
|
|
* .max_speed_hz = 5*1000*1000,
|
||
|
|
* .chip_select = 0,
