From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sergei Shtylyov Subject: [PATCH v5 06/12] ARM: dts: r8a7792: initial SoC device tree Date: Mon, 13 Jun 2016 00:06:52 +0300 Message-ID: <56384208.oM2NLZQo9N@wasted.cogentembedded.com> References: <14666252.G84Ipxe6EL@wasted.cogentembedded.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: In-Reply-To: <14666252.G84Ipxe6EL@wasted.cogentembedded.com> Sender: linux-renesas-soc-owner@vger.kernel.org To: horms@verge.net.au, linux-renesas-soc@vger.kernel.org, robh+dt@kernel.org, pawel.moll@arm.com, mark.rutland@arm.com, ijc+devicetree@hellion.org.uk, galak@codeaurora.org, devicetree@vger.kernel.org Cc: magnus.damm@gmail.com, linux@arm.linux.org.uk, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org The initial R8A7792 SoC device tree including CPU cores, GIC, timer, SYSC, and the required clock descriptions. Signed-off-by: Sergei Shtylyov Reviewed-by: Geert Uytterhoeven --- Changes in version 5: - removed the RCAN CPG clock; - added Geert's tag. Changes in version 4: - fixed the CP clock divisor; - indented the P clock's "compatible" prop correctly; - removed leftover DU0/1 clock names from the MSTP7 clock node. 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 | 179 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 179 insertions(+) Index: renesas/arch/arm/boot/dts/r8a7792.dtsi =================================================================== --- /dev/null +++ renesas/arch/arm/boot/dts/r8a7792.dtsi @@ -0,0 +1,179 @@ +/* + * 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.
