2017-10-26ARM: dts: mvebu: pl310-cache disable double-linefillYan Markman1-2/+2
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.

2017-10-02ARM: dts: Fix I2C repeated start issue on Armada-38xKalyan Kinthada1-2/+2
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.

2017-04-12ARM: dts: armada-38x: label USB and SATA nodesRalph Sennhauser1-4/+4
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).

2016-08-08ARM: dts: mvebu: A37x/XP/38x/39x: Move SPI controller nodes into 'soc' nodeStefan Roese1-24/+24
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.

2016-03-14ARM: dts: armada-38x: add buffer manager nodesMarcin Wojtas1-0/+19
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.

2016-02-09ARM: dts: armada-38x: change order of ethernet DT nodes on Armada 38xThomas Petazzoni1-9/+21
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.

2015-05-01ARM: mvebu: Fix the main PLL frequency on Armada 375, 38x and 39x SoCsGregory CLEMENT1-1/+1
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 for these last SoCs, there was no official value for the PLL. Now that 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.

2014-11-22ARM: mvebu: adjust ethernet aliases according to U-Boot requirements for A38xMarcin Wojtas1-3/+3
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.

2014-07-16ARM: mvebu: add CA9 MPcore SoC Controller nodeGregory CLEMENT1-0/+5
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.

2014-06-24ARM: mvebu: Fix the improper use of the compatible string armada38x using a ↵Gregory CLEMENT1-1/+1
wildcard Wildcards in compatible strings should be avoid. "marvell,armada38x" was recently introduced but was not yet used. The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs and more PCIe slots). So this patch replaces the use of "marvell,armada38x" by the "marvell,armada380" string.

2014-04-26ARM: mvebu: use clocks property for serial portsThomas Petazzoni1-0/+2
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 0bbeb3c3e84bc963d1c66661e082d207023b0e5c ('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.
