[ Upstream commit 64999fa7aa2c076ec6d05aee481f11f5296ceb8c ]
In randconfig builds without CONFIG_GENERIC_ALLOCATOR, this driver
fails to link:
ERROR: "gen_pool_alloc_algo" [drivers/fsi/fsi-master-ast-cf.ko] undefined!
ERROR: "gen_pool_fixed_alloc" [drivers/fsi/fsi-master-ast-cf.ko] undefined!
ERROR: "of_gen_pool_get" [drivers/fsi/fsi-master-ast-cf.ko] undefined!
ERROR: "gen_pool_free" [drivers/fsi/fsi-master-ast-cf.ko] undefined!
Select the dependency as all other users do.

|
---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
|

master that is connected to the upstream master via a slave. Hubs
|

allow chaining of FSI links to an arbitrary depth. This allows for
|

a high target device fanout.
