v4 cover Add platform support for LSI AXM55xx
Hi,
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.
Changes:
v4:
* Updated DTS according to new clk driver binding.
* Dropped the clk driver from this series.
v3:
* Sorted Kconfig entries alphabetically
v2:
* Rebased to arm-soc/for-next
* Removed redundant HAVE_SMP and ARCH_WANT_OPTIONAL_GPIOLIB from Kconfig
* Use CPU_METHOD_OF_DECLARE to register smp_operations
* Rework smp operations to avoid holding pen and custom headsmp.S
* Clean up board file
* Corrected clock properties for arm,sp804 dts node.
* Changed machine compatible strings to include full model number.
* Break out clk-axxia driver as separate patch
* Removed Makefile.boot

PATCH v4 1/5 ARM: Add platform support for LSI AXM55xx SoC
From: Anders Berg <[email protected]>
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.

Hi,
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.
I've merged it all into the next/soc branch now, thanks!
In the future when submitting patches for inclusion, please add the arm at kernel.org alias to Cc to ensure we don't miss it.
