2017-07-30ARM: dts: keystone-k2hk: Add DSP nodesSuman Anna
The Keystone 2 66AK2H/66AK2K SoCs have upto 8 TMS320C66x DSP Core Subsystems (C66x CorePacs), each with a 1.0 GHz or 1.2 GHz C66x Fixed/Floating-Point DSP Core, and 32 KB of L1P & L1D SRAMs and a 1 MB L2 SRAM. Add the DT nodes for these DSP processor sub-systems. The processors do not have an MMU, and use various IPC Generation registers and shared memory for inter-processor communication. The aliases with a stem 'rproc' have also been added for all the DSPs, they provide a fixed remoteproc id to each DSP processor.

2017-01-19ARM: dts: keystone-k2hk: Add PSC reset controller nodeSuman Anna
The Power Sleep Controller (PSC) module contains specific memory-mapped registers that can be used to perform reset management using specific bits for the DSPs available on the SoC. The PSC is defined using a syscon node, and the reset functionality is defined using a child syscon reset controller node. Add this syscon reset controller node as well as the reset control data for the resets it supports for the 66AK2H SoCs. Signed-off-by: Andrew F.

2017-01-07ARM: dts: keystone-k2hk: Reserve MSM RAM for boot monitorSuman Anna
The Keystone 2 boot monitor uses 32 KB of the MSM RAM @ 0x0c5f0000 on 66AK2H SoCs, so add a reserved child node for the same. This address is aligned to the values used within the latest boot monitor firmware [1] as of commit cf8b431e8b3b ("soc: Move load address to end of MSMC").

2017-01-07ARM: dts: keystone-k2hk: Add MSM RAM nodeSuman Anna
Add the RAM managed by the Multicore Shared Memory Controller (MSMC) as a mmio-sram node. The 66AK2H SoCs have 6 MB of such memory. Any specific MSM memory range needed by a software module ought to be reserved using an appropriate child node.

2016-04-13ARM: dts: k2*: Rename the k2* files to keystone-k2* filesNishanth Menon
As reported in [1], rename the k2* dts files to keystone-* files this will force consistency throughout. Script for the same (and hand modified for Makefile and MAINTAINERS files): for i in arch/arm/boot/dts/k2* do b=`basename $i`; git mv $i arch/arm/boot/dts/keystone-$b; sed -i -e "s/$b/keystone-$b/g" arch/arm/boot/dts/*[si] done NOTE: bootloaders that depend on older dtb names will need to be updated as well.
