From mboxrd@z Thu Jan 1 00:00:00 1970 From: Geert Uytterhoeven Subject: [PATCH/RFC v2 1/2] arm64: dts: r8a7795: Add support for R-Car H3 ES2.0 Date: Fri, 24 Mar 2017 14:37:44 +0100 Message-ID: <1490362665-4422-2-git-send-email-geert+renesas@glider.be> References: <1490362665-4422-1-git-send-email-geert+renesas@glider.be> Return-path: In-Reply-To: <1490362665-4422-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org> Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Simon Horman , Magnus Damm Cc: Yoshihiro Shimoda , Kuninori Morimoto , Laurent Pinchart , Wolfram Sang , Rob Herring , Mark Rutland , linux-renesas-soc-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, Geert Uytterhoeven List-Id: devicetree@vger.kernel.org Update r8a7795.dtsi so it corresponds to R-Car H3 ES2.0 or later: - The following devices no longer exist on ES2.0, and are thus removed: fcpf2, fcpvd3, fcpvi2, fdp1-2, usb3-if1, vspd3, vspi2. - The DU <-> VSPD topology is different on ES2.0, hence remove the "vsps" property from the DU node until the driver can handle this. Move support for the ES1.x revision of the R-Car H3 SoC into a separate file. To avoid duplication, r8a7795-es1.dtsi includes r8a7795.dtsi, add adds/removes/overrides device nodes and properties where needed. Switch r8a7795-salvator-x.dts and r8a7795-h3ulcb.dts from r8a7795.dtsi to r8a7795-es1.dtsi to preserve compatibility. Signed-off-by: Geert Uytterhoeven --- While currently r8a7795-es1.dtsi only adds device nodes, removal of devices nodes and properties can be implemented using the /delete-node/ and /delete-property/ keywords, as shown below: &soc { /delete-node/ @; }; & { /delete-property/ ; }; v2: - Use a separate file for ES1.x instead of for ES2.0, so r8a7795.dtsi always corresponds to the latest SoC revision, - Add a dash between SoC part number and revision, for compatibility with the BSP, - Enhance the hardware description from basic support to everything already supported on ES1.x (except for DU due VSP), - Let r8a7795-es1.dtsi include r8a7795.dtsi. --- arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi | 83 ++++++++++++++++++++++ arch/arm64/boot/dts/renesas/r8a7795-h3ulcb.dts | 4 +- arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 4 +- arch/arm64/boot/dts/renesas/r8a7795.dtsi | 70 +----------------- 4 files changed, 88 insertions(+), 73 deletions(-) create mode 100644 arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi diff --git a/arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi b/arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi new file mode 100644 index 0000000000000000..f1646334899f08ce --- /dev/null +++ b/arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi @@ -0,0 +1,83 @@ +/* + * Device Tree Source for the r8a7795 ES1.x SoC + * + * Copyright (C) 2015 Renesas Electronics Corp. + * + * This file is licensed under the terms of the GNU General Public License + * version 2.
