The ohci driver now calls clk_set_rate on the uhpck clock (which forwards
set_rate requests to its parent: the usb clock).

Add fixed regulator for vmmc0 and attach the vmmc for it to the mmc0
node on the SAM5D3 Xplained board. This will remove the following

The mmc1 channel is not populated on the SAM5D3 Xplained board, however
it is enabled and therefore the driver is attaching to it.
The node configuration for mmc1 is missing, so add an mmc1 node in the
device tree and set its status to disabled. Also add the vmmc and the
necessary slot configuration if this node were enabled to avoid the following
warnings from the driver:

commit 111573ccd89b ("mtd: atmel_nand: check NFC busy flag by HSMC_SR
instead of NFC cmd regs")
check NFC busy by nfc SR instead of NFC cmd regs. So we don't need to
map NFC cmd registers to include NFCBUSY bit.
That means we only need map 0x08000000 instead of 0x10000000 for NFC
cmd regs.
This patch reduce the NFC cmd regs map for sama5d3 & sama5d4.

The Berlin clock documentation was part of the Marvell Berlin SoC

chip controller. With the recent rework of the chip and system
controller handling (now all sub-devices of the soc and system
controller nodes are registred with simple-mfd, and each device has its
own sub-node), the documentation of the Berlin clock driver can be moved
to the generic clock documentation directory.

GPLv2-only devicetrees make reuse difficult for software components licensed
under a different license.
The consensus is that a GPL/X11 dual-license should allow all necessary uses,
so relicense the rk3288-evb files to this combination.
CCs were aquired by git shortlog -sne so it should've hopefully catched

This patch fixes a regression where serial is enabled by the first
(board) DTSI, then disabled by the second (SoC) file. To enable
serial and keep it enabled, we need to include the file which enables
it last.

There exists a tiny MMU, configurable only by the VC (running the
closed firmware), which maps from the ARM's physical addresses to bus
addresses. These bus addresses determine the caching behavior in the
VC's L1/L2 (note: separate from the ARM's L1/L2) according to the top
2 bits. The bits in the bus address mean:
From the VideoCore processor:
0x0... L1 and L2 cache allocating and coherent
0x4... L1 non-allocating, but coherent. L2 allocating and coherent
0x8... L1 non-allocating, but coherent. L2 non-allocating, but coherent
0xc... SDRAM alias. Cache is bypassed. Not L1 or L2 allocating or coherent
From the GPU peripherals (note: all peripherals bypass the L1
cache. The ARM will see this view once through the VC MMU):
0x0... Do not use
0x4... L1 non-allocating, and incoherent. L2 allocating and coherent.
0x8... L1 non-allocating, and incoherent. L2 non-allocating, but coherent
0xc... SDRAM alias. Cache is bypassed. Not L1 or L2 allocating or coherent
The 2835 firmware always configures the MMU to turn ARM physical
addresses with 0x0 top bits to 0x4, meaning present in L2 but
incoherent with L1. However, any bus addresses we were generating in
the kernel to be passed to a device had 0x0 bits. That would be a
reserved (possibly totally incoherent) value if sent to a GPU
peripheral like USB, or L1 allocating if sent to the VC (like a
firmware property request). By setting dma-ranges, all of the devices
below it get a dev->dma_pfn_offset, so that dma_alloc_coherent() and
friends return addresses with 0x4 bits and avoid cache incoherency.
This matches the behavior in the downstream 2708 kernel (see
BUS_OFFSET in arch/arm/mach-bcm2708/include/mach/memory.h).

Device tree node names should contain the node's reg property address value.
The i2c0 node was apparently forgotten in commit 25b2f1bd0b7e0 (ARM: bcm2835:
node name unit address cleanup).
