It appears that in haste, this fix for the native cs support broke the GPIO chip select support that I was originally shooting for. [ 2.653658] mcp23s08 spi1.1: TXS timed out [ 2.657961] mcp23s08 spi1.1: SPI transfer failed: -5 [ 2.663305] spi_master spi1: failed to transfer one message from queue [ 2.670172] mcp23s08 spi1.1: can't setup chip 64, --> -5 [ 2.675784] GPIO chip mcp23s08: gpiochip_unexport: status -19 My guess is that the set_cs needs to be called even when toggling as GPIO. How should I handle this? -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
