This change makes it possible for those devices to be detected by drivers that support the of_platform without having a custom call for each of them in the board file. Signed-off-by: Remi Machet (rmachet@slac.stanford.edu) --- Changes: v2: Use the compatible field to detect devices to register (on Dale Farnsworth suggestion). v3: Added __initdata to variable of_mv64x60_devices (thanks to Stephen Rothwell for pointing that out). v4: Re-wrote the patch description. arch/powerpc/sysdev/mv64x60_dev.c | 10 ++++++++++ 1 files changed, 10 insertions(+) diff --git a/arch/powerpc/sysdev/mv64x60_dev.c b/arch/powerpc/sysdev/mv64x60_dev.c index 41af122..c38695e 100644 --- a/arch/powerpc/sysdev/mv64x60_dev.c +++ b/arch/powerpc/sysdev/mv64x60_dev.c @@ -15,6 +15,7 @@ #include #include #include +#include #include @@ -25,6 +26,11 @@ * PowerPC of_platform_bus_type.
