[PATCH 08/20] arm64: dts: marvell: Add AP806-dual cache description

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Grzegorz Jaszczyk <jaz@xxxxxxxxxxxx>

Adding appropriate entries to device-tree allows the cache description
to show up in sysfs under: /sys/devices/system/cpu/cpuX/cache/.
