This patch series also includes patches for enabling IPC for am62x SK, am62ax SK, and am62px SK by reserving memory and binding the mailbox assignments for each remote core. Also reserve timers used by C7x DSP for am62ax SK board and timers used by MCU FW for AM642 SK and EVM boards as per firmware requirements. Changes since v4: - Drop SRAM node for am62px/am62ax MCU R5fSS0 core0 - Reserve timers for am64 MCU FW, patch 10/10 - Add "status = okay" for mailbox nodes at the board level, disabling of mailbox nodes in voltage domain .dtsi files will come in a separate series Links v4: https://lore.kernel.org/linux-devicetree/20250206235200.3128163-1-jm@ti.com/ v3: https://lore.kernel.org/linux-devicetree/20250204011641.1523561-1-jm@ti.com/ v2: https://lore.kernel.org/linux-devicetree/20250131214611.3288742-1-jm@ti.com/ v1: https://lore.kernel.org/linux-devicetree/20250127221631.3974583-1-jm@ti.com/ [0] https://www.ti.com/lit/pdf/spruj16 [1] https://www.ti.com/lit/pdf/spruiv7 Devarsh Thakkar (3): arm64: dts: ti: k3-am62a-wakeup: Add R5F device node arm64: dts: ti: k3-am62a7-sk: Enable IPC with remote processors arm64: dts: ti: k3-am62p5-sk: Enable IPC with remote processors Hari Nagalla (6): arm64: dts: ti: k3-am62-wakeup: Add wakeup R5F node arm64: dts: ti: k3-am62a-mcu: Add R5F remote proc node arm64: dts: ti: k3-am62x-sk-common: Enable IPC with remote processors arm64: dts: ti: k3-am62a7-sk: Reserve main_timer2 for C7x DSP arm64: dts: ti: k3-am62a7-sk: Reserve main_rti4 for C7x DSP arm64: dts: ti: k3-am64: Reserve timers used by MCU FW Jai Luthra (1): arm64: dts: ti: k3-am62a-main: Add C7xv device node arch/arm64/boot/dts/ti/k3-am62-wakeup.dtsi | 25 +++++ arch/arm64/boot/dts/ti/k3-am62a-main.dtsi | 12 ++ arch/arm64/boot/dts/ti/k3-am62a-mcu.dtsi | 25 +++++ arch/arm64/boot/dts/ti/k3-am62a-wakeup.dtsi | 25 +++++ arch/arm64/boot/dts/ti/k3-am62a7-sk.dts | 106 +++++++++++++++++- arch/arm64/boot/dts/ti/k3-am62p5-sk.dts | 50 ++++++++- .../arm64/boot/dts/ti/k3-am62x-sk-common.dtsi | 34 +++++- arch/arm64/boot/dts/ti/k3-am642-evm.dts | 17 +++ arch/arm64/boot/dts/ti/k3-am642-sk.dts | 17 +++ 9 files changed, 294 insertions(+), 17 deletions(-) base-commit: 2014c95afecee3e76ca4a56956a936e23283f05b
