SubjectHelp about chip select on SPI slave devices
Date
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 use 1
to 1 GPIO to CS(then needs 4 GPIOs).


Thanks in advance,
YiFei
