* ARM: dts: mvebu: Update with the new compatible string for mv64xxx-i2cGregory CLEMENT2013-09-17
| | | | | | | | | | | | | | | | The mv64xxx-i2c embedded in the Armada XP have a new feature to offload i2c transaction. This new version of the IP come also with some errata. This lead to the introduction to a another compatible string. This commit split the i2c information into armada-370.dtsi and armada-xp.dtsi. Most of the data remains the same and stay in the common file Armada-370-xp.dtsi. With this new feature the size of the registers are bigger for Armada XP and the new compatible string is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "marvell,armada-370-xp-timer" compatible string, together with the "marvell,timer-25Mhz" property are deprecated and should be removed from current DT. Instead, the timer DT nodes are now required to have an appropriate compatible string, which should be either "marvell,armada-370-timer" or "marvell,armada-xp-timer", depending on SoC. The clock property is now required only for Armada 370 so move it accordingly. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that mbus has been added to the device tree, it's possible to move the PCIe nodes out of internal registers, placing it directly below the mbus. This is a more accurate representation of the hardware. Moving the PCIe nodes, we now need to introduce an extra cell to encode the window target ID and attribute. Since this depends on the PCIe port, we split the ranges translation entries, to correspond to each MBus window.

* | ARM: mvebu: Add MBus to Armada 370/XP device treeEzequiel Garcia2013-08-06
|/ | | | | | | | | | | | | | | | | | | | The Armada 370/XP SoC family has a completely configurable address space handled by the MBus controller. This patch introduces the device tree layout of MBus, making the 'soc' node as mbus-compatible. Since every peripheral/controller is a child of this 'soc' node, this makes all of them sit behind the mbus, thus describing the hardware accurately. A translation entry has been added for the internal-regs mapping. This can't be done in the common armada-370-xp.dtsi because A370 and AXP have different addressing width.

| | | | | | | | | | | | | | | | In order to be able to use more than 4GB of RAM when the LPAE is activated, the dts must be converted in 64 bits. Only Armada XP is LPAE capable, but as it shares a common dtsi file with Armada 370, then the common file include the skeleton64. Thanks to the use of the overload capability of the device tree format, armada-370 include the 32 bit skeleton and all the armada 370 based dts can remain the same.

The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.

| | | | | | | | | | | | | The UART controller used in the Armada 370 and Armada XP SoCs is the Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The improper use of the ns16550 can lead to a kernel oops during boot if a character is sent to the UART before the initialization of the driver. The DW APB has an extra interrupt that gets raised when writing to the LCR when busy. This explains why we need to use dw-apb-uart driver to handle this.

Beside the SMP support itself brought by the last 3 commits, this series also adds the support for the coherency fabric unit and the power management service unit. The coherency fabric is responsible for ensuring hardware coherency between all CPUs and between CPUs and I/O masters. This unit is also available for Armada 370 and will be used in an incoming patch set for hardware I/O cache coherency. The power management service unit is responsible for powering down and waking up CPUs and other SOC units. Conflicts: arch/arm/mach-mvebu/armada-370-xp.c

| | * | arm: mvebu: fix compatible string in armada-370-xp.dtsiThomas Petazzoni2012-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the Device Tree files for Armada 370 and XP SoCs and boards use the "armada-370-xp" common compatible string, except armada-370-xp.dtsi which was specifying "armada_370_xp". Fix this inconsistency by making armada-370-xp.dtsi declare a compatible string of "armada-370-xp" like everyone else.

Theses SoCs come with an unit called coherency fabric. A beginning of the support for this unit have been introduced with the SMP patch set. This series extend this support: the coherency fabric unit allows to use the Armada XP and the Armada 370 as nearly coherent architectures. The third patches enables this new feature and register our own set of DMA ops, to benefit this hardware enhancement. The first patches exports a dma operation function needed to register our own set of dma ops. The second patch introduces a new flag for the address decoding configuration in order to be able to set the memory windows as shared memory.

This unit allows to use the Armada 370/XP as a nearly coherent architecture. The coherency mechanism uses snoop filters to ensure the coherency between caches, DRAM and devices. This mechanism needs a synchronization barrier which guarantees that all the memory writes initiated by the devices have reached their target and do not reside in intermediate write buffers. That's why the architecture is not totally coherent and we need to provide our own functions for some DMA operations. Beside the use of the coherency fabric, the device units will have to set the attribute flag of the decoding address window to select the accurate coherency process for the memory transaction. This is done each device driver programs the DRAM address windows. The value of the attribute set by the driver is retrieved through the orion_addr_map_cfg struct filled during the early initialization of the platform.
