Signed-off-by: Sergei Shtylyov --- Changes in version 3: - moved the fixed factor clocks under the "soc" node; - added back the CPU1 node, adjusted the changelog. Changes in version 2: - explicitly included the IRQ header; - removed the CPU1 node; - removed the audio and PCIe bus clocks; - removed the SDH, SD0, and SD1 CPG clocks; - added RCAN and ADSP CPG clocks; - removed the PLL1/2, Z2, ZS, I, B, P, CL, M2, RCLK, OSCCLK, ZB3, ZB3D2, DDR, and MP fixed factor clocks; - fixed up the parent and divisor for the CP fixed factor clock; - swapped the SYS-DMAC0/1 clocks; - removed all gated clocks except the [H]SCIF, IRQC, and SYS-DMAC ones; - created the "soc" subnode, moving the SoC device nodes there; - removed the "clocks" node, moving its fixed clock subnodes to the root and the MSTP subnodes into the "soc" node. arch/arm/boot/dts/r8a7792.dtsi | 180 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 180 insertions(+) Index: renesas/arch/arm/boot/dts/r8a7792.dtsi =================================================================== --- /dev/null +++ renesas/arch/arm/boot/dts/r8a7792.dtsi @@ -0,0 +1,180 @@ +/* + * Device Tree Source for the r8a7792 SoC + * + * Copyright (C) 2016 Cogent Embedded Inc. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
