Hi,
We have a board which has 1 SPI master controller and 4 SPI slave devices, and
we'd like to use 2 GPIOs to demux to chip select these slave devices.
Can anyone tell me if current powerpc dts support demuxer for chip select for
spi slave devices? So far as I know, in dts, SPI master can only
ect, then where is the
right place(which .c file) to set/pass platform_data to?
Regards,
YiFei

I'm a newbie for linux device driver development.
We have a custom ppc405 board which has MCP23S17
(16-Bit I/O Expander with SPI Interface) on it.
I noticed that current kernel has MCP23S08 driver
support, I'd like to know:
1. if passing platform data to MCP23S08 driver, can it make
