Patches from Anders Berg applied individually: Here is version 4 of platform support for AXM5516 SoC. The clk driver is now applied to clk-next. The rest should be ready for arm-soc. Haven't got any response from the power/reset maintainers... I hope this driver can be taken via arm-soc as well. The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15 cores (in a 4x4 cluster configuration). The cores within each cluster share an L2 cache, and the clusters are connected to each other via a CCN-504 cache coherent interconnect. This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located above 4GB in the memory map. * axxia/soc: ARM: dts: axxia: Add reset controller power: reset: Add Axxia system reset driver ARM: axxia: Adding defconfig for AXM55xx ARM: dts: Device tree for AXM55xx.

In the refactoring of the coherency fabric assembly code, a function called ll_get_cpuid() was created to factorize common logic between functions adding CPU to the SMP coherency group, enabling and disabling the coherency. However, the name of the function is highly misleading: ll_get_cpuid() makes one think tat it returns the ID of the CPU, i.e 0 for CPU0, 1 for CPU1, etc. In fact, this is not at all what this function returns: it returns a CPU mask for the current CPU, usable for the coherency fabric configuration and control registers. Therefore this commit renames this function to ll_get_coherency_cpumask(), and adds additional comments on top of the function to explain in more details what it does, and also how the endianess issue is handled.

As part of the introduction of the cpuidle support for Armada XP, the coherency code was significantly reworked, especially in the coherency_ll.S file. However, when the ll_get_cpuid function was created, the big-endian specific code that switches the endianess of the register was not updated properly. This patch fixes this code, and therefore makes big endian systems bootable again. Signed-off-by:

Commit b0063aad ("ARM: mvebu: use hardware I/O coherency also for PCI devices") added a reference to the pci_bus_type variable, but this variable is only available when CONFIG_PCI is enabled. Therefore, there is now a build failure in !CONFIG_PCI situations. This commit fixes that by enclosing the entire initcall into a IS_ENABLED(CONFIG_PCI) condition. Reported-by:

Thomas Petazzoni authored
The Marvell Armada 375 and Armada 38x SOCs, which use the Cortex-A9 CPU core, the PL310 cache and the Marvell PCIe hardware block are affected a L2/PCIe deadlock caused by a system erratum when hardware I/O coherency is used. This deadlock can be avoided by mapping the PCIe memory areas as strongly-ordered (note: MT_UNCACHED is strongly-ordered), and by removing the outer cache sync done in software. This is implemented in this patch by: * Registering a custom arch_ioremap_caller function that allows to make sure PCI memory regions are mapped MT_UNCACHED. * Adding at runtime the 'arm,io-coherent' property to the PL310 cache controller. This cannot be done permanently in the DT, because the hardware I/O coherency can only be enabled when CONFIG_SMP is enabled, in the current kernel situation. Signed-off-by:

Since the beginning of the introduction of hardware I/O coherency support for Armada 370 and Armada XP, the special DMA operations should have applied to all DMA capable devices. Unfortunately, while the original code properly took into account platform devices, it didn't take into account PCI devices, which can also be DMA masters. This commit fixes that by registering a bus notifier on pci_bus_type, to register our custom DMA operations, like is already done for platform devices. While doing this, we also rename mvebu_hwcc_platform_notifier() to mvebu_hwcc_notifier() and mvebu_hwcc_platform_nb to mvebu_hwcc_nb because they are no longer specific to platform devices.

shmobile_init_delay() looks for OF "clock-frequency" to determine the delay which is set by calling shmobile_setup_delay(). Unfortunately this seems to be incorrect in detail as "clock-frequency" node values are in HZ whereas the frequency argument to shmobile_setup_delay() is in MHz. Provide a variant of shmobile_setup_delay() that accepts HZ to correct this problem. Signed-off-by:Simon Horman <horms+renesas@verge.net.au>
