I haven't seen this before - the '##' in the function name. This is ANCII C?
#define MPC83XX_SPI_TX_BUF(type) \
u32 mpc83xx_spi_tx_buf_##type(struct mpc83xx_spi *mpc83xx_spi) \
{ \
u32 data; \
....
Also, I have a SPI chip here that will drive MISO high when it is
ready to accept more data. It acts like a hardware handshake. I was
thinking about making changes to the controller source (spi_mpc83xx.c,
in my case) to support this.
This is the only SPI chip contained on this system so I am not worried
about affecting other SPI devices hooked to the controller.
What are people's opinion on this as far as right place to implement,
and I could use a push as to where in the controller to make mods if
appropriate.
And if it isn't obvious already I am still learning a bit as to how
the SPI sub-system is organized. I have taken apart the
documentation in the kernel Documentation/spi directory and am reading
all the code in drivers/spi.
