Yan Markman cda80a82ac ARM: dts: mvebu: pl310-cache disable double-linefill
Under heavy system stress mvebu SoC using Cortex A9 sporadically
encountered instability issues.

The "double linefill" feature of L2 cache was identified as causing
dependency between read and write which lead to the deadlock.

Especially, it was the cause of deadlock seen under heavy PCIe traffic,
as this dependency violates PCIE overtaking rule.

Kalyan Kinthada fbffee7498 ARM: dts: Fix I2C repeated start issue on Armada-38x
All the Armada 38x(380, 385, 388) have a silicon issue in
the I2C controller which violates the I2C repeated start timing
(errata FE-8471889).

i2c-mv64xxx driver handles this errata based on the compatible string
"marvell,mv78230-a0-i2c".

This patch activates the "marvell,mv78230-a0-i2c" compatible string
for the I2C controller on armada-38x SoC based devices.

Ralph Sennhauser f3d1f7597e ARM: dts: armada-38x: label USB and SATA nodes
Recently most nodes got labels to make them referenceable. The USB 3.0
nodes as well as the nodes for the SATA controllers were left out,
rectify the omission.

The labels "sataX" are already used by some boards for the SATA ports,
therefore use "ahciX" to label the SATA controller nodes.

To avoid potential confusion by labeling an USB3.0 controller "usb2" use
usb3_X as labels. This also coincides with the node names themselves
(usb@xxxxx vs usb3@xxxxx).

Stefan Roese 0160a4b689 ARM: dts: mvebu: A37x/XP/38x/39x: Move SPI controller nodes into 'soc' node
This patch moves all Armada 370/XP/38x/39x SPI controller nodes from the
'internal-regs' node down into the 'soc' node. This is in preparation
to enable the usage of the SPI direct access mode. A follow-up patch
will add the static MBus mappings for the SPI devices into the 'reg'
property of the SPI controller DT node.

By moving these SPI controller nodes, this patch also makes use of
the labels rather than keeping the tree structure.

Marcin Wojtas 4a547a5a46 ARM: dts: armada-38x: add buffer manager nodes
Armada 38x network controller supports hardware buffer management (BM).
Since it is now enabled in mvneta driver, appropriate nodes can be added
to armada-38x.dtsi - for the actual common BM unit (bm@c8000) and its
internal SRAM (bm-bppi), which is used for indirect access to buffer
pointer ring residing in DRAM.

Pools - ports mapping, bm-bppi entry in 'soc' node's ranges and optional
parameters are supposed to be set in board files.

Thomas Petazzoni cb4f71c429 ARM: dts: armada-38x: change order of ethernet DT nodes on Armada 38x
On Armada 38x, the available network interfaces are:

 - port 0, at 0x70000
 - port 1, at 0x30000
 - port 2, at 0x34000

Due to the rule saying that DT nodes should be ordered by register
addresses, the network interfaces are probed in this order:

 - port 1, at 0x30000, which gets named eth0
 - port 2, at 0x34000, which gets named eth1
 - port 0, at 0x70000, which gets named eth2

(if all three ports are enabled at the board level)

Unfortunately, the network subsystem doesn't provide any way to rename
network interfaces from the kernel (it can only be done from
userspace). So, the default naming of the network interfaces is very
confusing as it doesn't match the datasheet, nor the naming of the
interfaces in the bootloader, nor the naming of the interfaces on
labels printed on the board.

For example, on the Armada 388 GP, the board has two ports, labelled
GE0 and GE1. One has to know that GE0 is eth1 and GE1 is eth0, which
isn't really obvious.

In order to solve this, this patch proposes to exceptionaly violate
the rule of "order DT nodes by register address", and put the 0x70000
node before the 0x30000 node, so that network interfaces get named in
a more natural way.

Whereas for Armada 370 and XP the main PLL frequency was 2GHz for the
Armada 375, 38x and 39x, the frequency is 1GHz. When writing support

we have it, this patch fixes it in the device tree.

This value is currently only used by the NAND driver for the setting
the NAND timing. Fortunately it is not actually used: all the mainline
board with a NAND flash comes with a NAND device tree node using the
"marvell,nand-keep-config" property. With this property the timings
are not modified in the kernel driver and are kept from the
bootloader.

Instead of hardcoding the values of the interrupt flags, use the
macros provided by <include/dt-bindings/interrupt-controller/irq.h>
and <include/dt-bindings/interrupt-controller/arm-gic.h> for the
Armada 38x SDHCI node.

Linus Torvalds a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.

Due to the special handling of window 13 on Armada 375 and Armada 38x
(similar to Armada XP), the MBus hardware block is *not* compatible
with the one used on Armada 370. Using the Armada 370 compatible
string on Armada 375 and 38x will lead to a non-working device if
window 13 ends up being used.

Marcin Wojtas ad6a1b445b ARM: mvebu: adjust ethernet aliases according to U-Boot requirements for A38x
In order to update MAC address entries in the ethernet nodes in Device Tree
both mainline U-Boot and Barebox bootloaders accept the same format of aliases,
which is 'ethernetX', where X stands for an interface number.
Other platforms in the mainline Linux, that comprise ethernet references in
'/aliases' node (like various flavours of imx or sunXi), follow the naming
scheme described above.

This commit ajusts ethernet aliases of Marvell Armada 38x SoC to be properly
recognized by bootloaders' MAC address fixup routines.

Gregory CLEMENT d7f3ec2b69 ARM: mvebu: add CA9 MPcore SoC Controller node
The CA9 MPcore SoC Control block is a set of registers that allows to
configure certain internal aspects of the core blocks of the SoC
(Cortex-A9, L2 cache controller, etc.). In most cases, the default
values are fine so they aren't many reasons to touch those registers,
but there is one exception: to support cpuidle on Armada 38x, we need
to modify the value of the CA9 MPcore Reset Control register.

Therefore, this commit adds a new Device Tree binding for this
hardware block, and uses this new binding for the Armada 38x Device
Tree file.

Wildcards in compatible strings should be avoid. "marvell,armada38x"

The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs

"marvell,armada38x" by the "marvell,armada380" string.

Thomas Petazzoni 64939dc5bf ARM: mvebu: use clocks property for serial ports
Back when the Armada 370 and Armada XP initial support was introduced,
the only way to pass the clock frequency to the of_serial driver was
through a clock-frequency Device Tree property.

Thanks to 0bbeb3c3e8 ('of serial port
driver - add clk_get_rate() support'), it is possible to use the
standard 'clocks' DT property to reference the clock used for a
particular UART controller. This clock is then used by the of_serial
driver to retrieve the clock rate.

This commit modifies the SoC-level Device Tree files of Armada 370,
Armada XP, Armada 375 and Armada 38x to use this possibility. Since
there is no gatable clock for the UART controllers, we simply
reference the TCLK, which is the main SoC clock for the peripherals.
