Currently CONFIG_FSI_MASTER_ASPEED=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:
ld: drivers/fsi/fsi-master-aspeed.o: in function `fsi_master_aspeed_probe':
drivers/fsi/fsi-master-aspeed.c:436: undefined reference to `devm_ioremap_resource'
Fix the build error by adding the unspecified dependency.
Fixes: 606397d67f ("fsi: Add ast2600 master driver")

|
---help---
|
|
This option causes char devices created for FSI devices to be
|
|
located under a common /dev/fsi/ directory. Set to N unless your
|
|
userspace has been updated to handle the new location.
|
|
|
|
Additionally, it also causes the char device names to be offset
|
|
by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2
|
|
to match old userspace expectations.
|
|
|
|
New userspace will use udev rules to generate predictable access
|
|
symlinks in /dev/fsi/by-path when this option is enabled.

This option enables a FSI hub master driver. Hub is a type of FSI

a high target device fanout.
