[PATCH v3 01/10] pinctrl: walk into bcm subdir unconditionally

[Gerd Hoffmann]

There is no ARCH_BCM on arm64, and we need pinctrl-bcm2835 for the rpi3.

[PATCH v3 03/10] arm64: Allow for different DMA and CPU bus offsets

[Gerd Hoffmann]

From: Alexander Graf <agraf@suse.de>

On arm64, all SoCs we supported so far either have an IOMMU or have bus
addresses equal to CPU addresses.

However, with the Raspberry Pi 3 coming up, this is no longer true. To
allow DMA to work with an AArch64 kernel on those devices, let's allow
devices to have DMA offsets again.

[PATCH v3 09/10] ARM: bcm2835: dt: Add the ethernet to the device trees

[Gerd Hoffmann]

From: Lubomir Rintel <lkundrak@v3.sk>

The hub and the ethernet in its port 1 are hardwired on the board.

Compared to the adapters that can be plugged into the USB ports, this
one has no serial EEPROM to store its MAC. Nevertheless, the Raspberry Pi
has the MAC address for this adapter in its ROM, accessible from its
firmware.

U-Boot can read out the address and set the local-mac-address property of the
node with "ethernet" alias. Let's add the node so that U-Boot can do its
business.

Model B rev2 and Model B+ entries were verified by me, the hierarchy and
pid/vid pair for the Version 2 was provided by Peter Chen. Original
Model B is a blind shot, though very likely correct.
