Merge branch 'axxia/soc' into next/soc
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. ARM: Add platform support for LSI AXM55xx SoC Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Required root node property:

Axxia Restart Driver
|
||||||
|
|
||||||
|
This driver can do reset of the Axxia SoC. It uses the registers in the syscon
|
||||||
|
block to initiate a chip reset.
|
||||||
|
|
||||||
|
Required Properties:
|
||||||
|
-compatible: "lsi,axm55xx-reset"
|
||||||
|
-syscon: phandle to the syscon node.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
syscon: syscon@2010030000 {
|
||||||
|
compatible = "lsi,axxia-syscon", "syscon";
|
||||||
|
reg = <0x20 0x10030000 0 0x2000>;
|
||||||
|
};
|
||||||
|
|
||||||
|
reset: reset@2010031000 {
|
||||||
|
compatible = "lsi,axm55xx-reset";
|
||||||
|
syscon = <&syscon>;
|
