There is one GPIO controlling power for both USB ports.

* [PATCH V2 4/5] ARM: BCM5301X: Specify all RAM by including an extra block

The first 128 MiB of RAM can be accessed using an alias at address 0x0.

In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
range can't be used. I reproduced this problem on:
1) Buffalo WZR-600DHP2 (BCM47081)
2) Netgear R6250 (BCM4708)
3) D-Link DIR-885L (BCM47094)

So it seems we're forced to access first 128 MiB using alias at 0x0 and
the rest using real base address + 128 MiB offset which is 0x88000000.

* [PATCH V2 4/5] ARM: BCM5301X: Specify all RAM by including an extra block

From: Rafał Miłecki <rafal-g1n6cQUeyibVItvQsEIGlw@public.gmane.org>

The first 128 MiB of RAM can be accessed using an alias at address 0x0.

In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
range can't be used. I reproduced this problem on:
1) Buffalo WZR-600DHP2 (BCM47081)
2) Netgear R6250 (BCM4708)
3) D-Link DIR-885L (BCM47094)

So it seems we're forced to access first 128 MiB using alias at 0x0 and
the rest using real base address + 128 MiB offset which is 0x88000000.

* [PATCH V2 5/5] ARM: BCM53573: Specify USB ports of on-SoC controllers
@ 2016-12-07  7:56   ` Rafał Miłecki

  To: linux-arm-kernel

From: Rafa? Mi?ecki <rafal@milecki.pl>

Broadcom OHCI and EHCI controllers always have 2 ports each on the root
hub. Describe them in DT to allow specifying extra info or referencing
port nodes.
