The node is disabled in the base dts file, and enabled in the corresponding LCDK board file alongside the reserved CMA pool required by the DSP device. The DT bindings and driver adaptation were added to mainline in 4.14-rc1, and this series adds the remaining dt portions. Nodes are added as per bindings in Documentation/devicetree/bindings/remoteproc/ti,davinci-rproc.txt Patches are based on 4.14-rc1. The first 2 patches adds the base DTS node and enables the device on OMAPL138 LCDK board. The last patch allows the non-DT clock to be bound to the DT DSP device by using of_auxdata which renames the device to the same as the non-DT device name. This is required by the davinci remoteproc driver to properly acquire and enable the clock for this device. Validation done on OMAPL138 LCDK board. Supported features include basic load/boot (tested with rpmsg_client_sample) using external memory from the CMA pool. regards Suman Suman Anna (3): ARM: dts: da850: Add DSP node ARM: dts: da850-lcdk: Add and enable CMA reserved pool for DSP ARM: davinci: da8xx-dt: Add OF_DEV_AUXDATA entry for DSP clock matching arch/arm/boot/dts/da850-lcdk.dts | 18 ++++++++++++++++++ arch/arm/boot/dts/da850.dtsi | 12 ++++++++++++ arch/arm/mach-davinci/da8xx-dt.c | 1 + 3 files changed, 31 insertions(+) -- 2.13.1
