[PATCH 10/20] arm64: dts: marvell: Add AP807-quad cache description

From: Miquel Raynal <miquel.raynal@bootlin.com>
Date: 2019-08-06 14:54:50
Also in: linux-devicetree
Subsystem: arm/marvell kirkwood and armada 370, 375, 38x, 39x, xp, 3700, 7k/8k, cn9130 soc support, the rest · Maintainers: Andrew Lunn, Gregory Clement, Sebastian Hesselbarth, Linus Torvalds

From: Grzegorz Jaszczyk <redacted>

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