It can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). The TCMs of both Cores are combined in LockStep-mode to provide a larger 128 KB of memory, but otherwise are functionally similar to those on J721E SoCs. Add the DT nodes for the MCU domain R5F cluster/subsystem, the two R5F cores are added as child nodes to each of the R5F cluster nodes. The clusters are configured to run in LockStep mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes. The following firmware names are used by default for these cores, and can be overridden in a board dts file if desired: MCU R5FSS0 Core0: j721s2-mcu-r5f0_0-fw (both in LockStep and Split mode) MCU R5FSS0 Core1: j721s2-mcu-r5f0_1-fw (needed only in Split mode) Signed-off-by: Hari Nagalla Signed-off-by: Apurva Nandan --- .../boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi | 40 +++++++++++++++++++ 1 file changed, 40 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi b/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi index 736ec5fa0ea2..d4624d8461b2 100644 --- a/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi @@ -652,4 +652,44 @@ wkup_vtm0: temperature-sensor@42040000 { power-domains = <&k3_pds 154 TI_SCI_PD_SHARED>; #thermal-sensor-cells = <1>; }; + + mcu_r5fss0: r5fss@41000000 { + compatible = "ti,j721s2-r5fss"; + ti,cluster-mode = <1>; + #address-cells = <1>; + #size-cells = <1>; + ranges = <0x41000000 0x00 0x41000000 0x20000>, + <0x41400000 0x00 0x41400000 0x20000>; + power-domains = <&k3_pds 283 TI_SCI_PD_EXCLUSIVE>; + + mcu_r5fss0_core0: r5f@41000000 { + compatible = "ti,j721s2-r5f"; + reg = <0x41000000 0x00010000>, + <0x41010000 0x00010000>; + reg-names = "atcm", "btcm"; + ti,sci = <&sms>; + ti,sci-dev-id = <284>; + ti,sci-proc-ids = <0x01 0xff>; + resets = <&k3_reset 284 1>; + firmware-name = "j721s2-mcu-r5f0_0-fw"; + ti,atcm-enable = <1>; + ti,btcm-enable = <1>; + ti,loczrama = <1>; + }; + + mcu_r5fss0_core1: r5f@41400000 { + compatible = "ti,j721s2-r5f"; + reg = <0x41400000 0x00010000>, + <0x41410000 0x00010000>; + reg-names = "atcm", "btcm"; + ti,sci = <&sms>; + ti,sci-dev-id = <285>; + ti,sci-proc-ids = <0x02 0xff>; + resets = <&k3_reset 285 1>; + firmware-name = "j721s2-mcu-r5f0_1-fw"; + ti,atcm-enable = <1>; + ti,btcm-enable = <1>; + ti,loczrama = <1>; + }; + }; }; From patchwork Fri Aug 11 20:22:50 2023 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit X-Patchwork-Submitter: Apurva Nandan X-Patchwork-Id: 712958 Return-Path: X-Spam-Checker-Version: SpamAssassin 3.4.0 (2014-02-07) on aws-us-west-2-korg-lkml-1.web.codeaurora.org Received: from vger.kernel.org (vger.kernel.org [23.128.96.18]) by smtp.lore.kernel.org (Postfix) with ESMTP id 6BA24C04A6A for ; Fri, 11 Aug 2023 20:23:18 +0000 (UTC) Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S234061AbjHKUXR (ORCPT ); Fri, 11 Aug 2023 16:23:17 -0400 Received: from lindbergh.monkeyblade.net ([23.128.96.19]:51336 "EHLO lindbergh.monkeyblade.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S234049AbjHKUXN (ORCPT ); Fri, 11 Aug 2023 16:23:13 -0400 Received: from fllv0016.ext.ti.com (fllv0016.ext.ti.com [198.47.19.142]) by lindbergh.monkeyblade.net (Postfix) with ESMTPS id 0B759127; Fri, 11 Aug 2023 13:23:13 -0700 (PDT) Received: from fllv0035.itg.ti.com ([10.64.41.0]) by fllv0016.ext.ti.com (8.15.2/8.15.2) with ESMTP id 37BKN7w1075359; Fri, 11 Aug 2023 15:23:07 -0500 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=ti.com; s=ti-com-17Q1; t=1691785387; bh=jg8Y/efRnd00jCD8mXhMShT//N8ycOku0P1y8NBikN8=; h=From:To:Subject:Date:In-Reply-To:References; b=bF/xbLMZy+6FGEsBZrzj3umiQargxyduCrrTH/nYlYCZDj+oxYL5CJWyuspowonNv CAmai9Jv8klmLSPltQXubV0DZvn/HN6325oh2qL5zatE+YI1tdQu50Jkr4HW6YJhAE MHU2xF4Ak4D62aFSmnaDvhMqnTBSPI2Ap8/cwnag= Received: from DFLE103.ent.ti.com (dfle103.ent.ti.com [10.64.6.24]) by fllv0035.itg.ti.com (8.15.2/8.15.2) with ESMTPS id 37BKN7lq124280 (version=TLSv1.2 cipher=AES256-GCM-SHA384 bits=256 verify=FAIL); Fri, 11 Aug 2023 15:23:07 -0500 Received: from DFLE105.ent.ti.com (10.64.6.26) by DFLE103.ent.ti.com (10.64.6.24) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256_P256) id 15.1.2507.23; Fri, 11 Aug 2023 15:23:07 -0500 Received: from lelv0327.itg.ti.com (10.180.67.183) by DFLE105.ent.ti.com (10.64.6.26) with Microsoft SMTP Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256_P256) id 15.1.2507.23 via Frontend Transport; Fri, 11 Aug 2023 15:23:07 -0500 Received: from TI.dhcp.ti.com (ileaxei01-snat2.itg.ti.com [10.180.69.6]) by lelv0327.itg.ti.com (8.15.2/8.15.2) with ESMTP id 37BKMr56055948; Fri, 11 Aug 2023 15:23:04 -0500 From: Apurva Nandan To: Apurva Nandan , Nishanth Menon , Vignesh Raghavendra , Tero Kristo , Rob Herring , Krzysztof Kozlowski , Conor Dooley , , , , Hari Nagalla , Udit Kumar Subject: [PATCH v3 3/5] arm64: dts: ti: k3-j721s2-main: Add C7x remote processsor nodes Date: Sat, 12 Aug 2023 01:52:50 +0530 Message-ID: <20230811202252.3586926-4-a-nandan@ti.com> X-Mailer: git-send-email 2.34.1 In-Reply-To: <20230811202252.3586926-1-a-nandan@ti.com> References: <20230811202252.3586926-1-a-nandan@ti.com> MIME-Version: 1.0 X-EXCLAIMER-MD-CONFIG: e1e8a2fd-e40a-4ac6-ac9b-f7e9cc9ee180 Precedence: bulk List-ID: X-Mailing-List: devicetree@vger.kernel.org The K3 J721S2 SoCs have two C71x DSP subsystems in MAIN voltage domain.
