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 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
