Hi Fedora kernel team,
I'd like to access SPI devices via the spidev user API ([1]) on
my Fedora
system.
Would it be possible to enable CONFIG_SPI_SPIDEV (module would be
fair
enough),
so that I don't have to build my own kernel?
Which architectures or sort of device?
I'd like to have that for x86-64 (I want to control an SPI-attached
display).
Any particular drivers? Or just SPI_SPIDEV
FWIW, in RHEL we have
./redhat/configs/debug/aarch64/CONFIG_SPI_DEBUG:CONFIG_SPI_DEBUG=y
./redhat/configs/generic/aarch64/CONFIG_SPI:CONFIG_SPI=y
./redhat/configs/generic/aarch64/CONFIG_SPI_CADENCE:CONFIG_SPI_CADENCE=m
./redhat/configs/generic/aarch64/CONFIG_SPI_MASTER:CONFIG_SPI_MASTER=y
./redhat/configs/generic/aarch64/CONFIG_SPI_PL022:CONFIG_SPI_PL022=m
./redhat/configs/generic/aarch64/CONFIG_SPI_QUP:CONFIG_SPI_QUP=y
./redhat/configs/generic/aarch64/CONFIG_SPI_XLP:CONFIG_SPI_XLP=m
./redhat/configs/generic/x86_64/CONFIG_SPI:CONFIG_SPI=y
I don't have a problem with these going in the 5.0 rebase.
We already have it all enabled on aarch64, and Arm in general, I
actually question how useful the RHEL config is on non aarch64 as it
doesn't enable CONFIG_SPI_SPIDEV or CONFIG_SPI_MASTER which I think
are generally needed for it to be useful, but maybe CONFIG_SPI enables
them, I've not looked.
CONFIG_SPI is required for any CONFIG_SPI*.
CONFIG_SPI_MASTER is required for CONFIG_SPI_SPIDEV.

I've turned on SPI_SPIDEV on x86 and it's in today's Rawhide build. I've
also pushed it to the f30 branch so it should be in the 5.0.2 build.
