Imagine scaling down your CPU voltage and then getting a watchdog reset. Your CPU might not appreciate coming out of reset with full frequency but not enough voltage. If you regular reset is via PMIC, your watchdog reset should go through the PMIC as well. > +}; > + > +&m4_rproc { > + memory-region = <&retram>, <&mcuram>, <&mcuram2>, <&vdev0vring0>, > + <&vdev0vring1>, <&vdev0buffer>; > + mboxes = <&ipcc 0>, <&ipcc 1>, <&ipcc 2>; > + mbox-names = "vq0", "vq1", "shutdown"; > + interrupt-parent = <&exti>; > + interrupts = <68 1>; > + status = "okay"; > +}; > + > +&rng1 { > + status = "okay"; > +}; > + > +&rtc { > + status = "okay"; > +}; > + > +&sdmmc2 { > + pinctrl-names = "default", "opendrain", "sleep"; > + pinctrl-0 = <&sdmmc2_b4_pins_a &sdmmc2_d47_pins_a>; > + pinctrl-1 = <&sdmmc2_b4_od_pins_a &sdmmc2_d47_pins_a>; > + pinctrl-2 = <&sdmmc2_b4_sleep_pins_a &sdmmc2_d47_sleep_pins_a>; > + non-removable; > + no-sd; > + no-sdio; > + st,neg-edge; > + bus-width = <4>; > + vmmc-supply = <&v3v3>; > + vqmmc-supply = <&v3v3>; > + mmc-ddr-3_3v; > + status = "okay"; > +}; > + > diff --git a/arch/arm/boot/dts/stm32mp157c-odyssey.dts b/arch/arm/boot/dts/stm32mp157c-odyssey.dts > new file mode 100644 > index 000000000000..6c1b091af14f > --- /dev/null > +++ b/arch/arm/boot/dts/stm32mp157c-odyssey.dts > @@ -0,0 +1,72 @@ > +// SPDX-License-Identifier: (GPL-2.0+ OR BSD-3-Clause) > +/* > + * Copyright (C) 2020 Marcin Sloniewski <marcin.sloniewski@gmail.com>. > + */ > + > +/dts-v1/; > + > +#include "stm32mp157c-odyssey-som.dtsi" > + > +/ { > + model = "Seeed Studio Odyssey-STM32MP157C Board"; > + compatible = "seeed,stm32mp157c-odyssey", "st,stm32mp157"; A compatible for the SoM here could be useful as well, e.g. if bootloader needs to apply some fixups specific to the SoM. > + > + aliases { > + ethernet0 = ðernet0; > + serial0 = &uart4; > + }; > + > + chosen { > + stdout-path = "serial0:115200n8"; > + }; > +}; > + > +ðernet0 { > + status = "okay"; > + pinctrl-0 = <ðernet0_rgmii_pins_a>; > + pinctrl-1 = <ðernet0_rgmii_pins_sleep_a>; > + pinctrl-names = "default", "sleep"; > + phy-mode = "rgmii-id"; > + max-speed = <1000>; > + phy-handle = <&phy0>; > + > + mdio0 { > + #address-cells = <1>; > + #size-cells = <0>; > + compatible = "snps,dwmac-mdio"; > + phy0: ethernet-phy@0 { Nitpick: I like it when there is a comment about the PHY in use. > + reg = <0>; Address 0 is the SMI broadcast address.

However, there's no need to repost patches *only* to add the tags. The upstream maintainer will do that for acks received on the version they apply. If a tag was not added on purpose, please state why and what changed.
