Hi Santosh, The following series adds the DT nodes for the DSP devices present on the Keystone2 66AK2H/K, 66AK2L and 66AK2E SoCs. They are disabled in the base dts files, and enabled in the corresponding board files alongside an added common reserved CMA pool that is used by all the DSP devices. The bindings and driver support were added to mainline in 4.13-rc1, and this series adds the dt portions. Nodes are added as per bindings in Documentation/devicetree/bindings/remoteproc/ti,keystone-rproc.txt Validation done on K2HK EVM, K2L EVM and K2E EVM. Supported features include basic load/boot (tested with rpmsg_client_sample) and Error Recovery (after reverting a patch merged in 4.13-rc1 that has caused a kernel crash, see [1]). Functionality with CMA nodes from HighMem require a patch in the virtio_rpmsg_bus core [2]. regards Suman [1] http://marc.info/?l=linux-arm-kernel&m=150127179030802&w=2 [2] https://patchwork.kernel.org/patch/9549911/ Sam Nelson (3): ARM: dts: keystone-k2hk-evm: Add and enable common DSP CMA memory pool ARM: dts: keystone-k2l-evm: Add and enable common DSP CMA memory pool ARM: dts: keystone-k2e-evm: Add and enable DSP CMA memory pool Suman Anna (3): ARM: dts: keystone-k2hk: Add DSP nodes ARM: dts: keystone-k2l: Add DSP nodes ARM: dts: keystone-k2e: Add DSP node arch/arm/boot/dts/keystone-k2e-evm.dts | 18 +++++ arch/arm/boot/dts/keystone-k2e.dtsi | 20 +++++ arch/arm/boot/dts/keystone-k2hk-evm.dts | 53 ++++++++++++ arch/arm/boot/dts/keystone-k2hk.dtsi | 139 ++++++++++++++++++++++++++++++++ arch/arm/boot/dts/keystone-k2l-evm.dts | 33 ++++++++ arch/arm/boot/dts/keystone-k2l.dtsi | 71 ++++++++++++++++ 6 files changed, 334 insertions(+) -- 2.13.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
