But J722S has additional peripherals that are not present in AM62P. Introduce a -main.dtsi to define such additional main domain peripherals and define the SERDES0 node. Signed-off-by: Ravi Gunasekaran --- Changes since v1: ---------------- * Newly introduced k3-j722s-main.dtsi to add main domain peripherals that are additionally present in J722S * Used generic node names - renamed "clock-cmnrefclk" to "clk-0", "wiz@f000000" to "phy@f000000" v1: https://lore.kernel.org/all/20240429120932.11456-1-r-gunasekaran@ti.com/ arch/arm64/boot/dts/ti/k3-j722s-main.dtsi | 64 +++++++++++++++++++++++ 1 file changed, 64 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-j722s-main.dtsi diff --git a/arch/arm64/boot/dts/ti/k3-j722s-main.dtsi b/arch/arm64/boot/dt= s/ti/k3-j722s-main.dtsi new file mode 100644 index 000000000000..1fd88cc8545f --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-j722s-main.dtsi @@ -0,0 +1,64 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/* + * Device Tree file for the J722S main domain peripherals + * Copyright (C) 2023-2024 Texas Instruments Incorporated - https://www.ti= .com/ + */ + +#include + +/ { + serdes_refclk: clk-0 { + compatible =3D "fixed-clock"; + #clock-cells =3D <0>; + clock-frequency =3D <0>; + }; +}; + +&cbass_main { + serdes_wiz0: phy@f000000 { + compatible =3D "ti,am64-wiz-10g"; + ranges =3D <0x0f000000 0x0 0x0f000000 0x00010000>; + #address-cells =3D <1>; + #size-cells =3D <1>; + power-domains =3D <&k3_pds 279 TI_SCI_PD_EXCLUSIVE>; + clocks =3D <&k3_clks 279 0>, <&k3_clks 279 1>, <&serdes_refclk>; + clock-names =3D "fck", "core_ref_clk", "ext_ref_clk"; + num-lanes =3D <1>; + #reset-cells =3D <1>; + #clock-cells =3D <1>; + + assigned-clocks =3D <&k3_clks 279 1>; + assigned-clock-parents =3D <&k3_clks 279 5>; + + serdes0: serdes@f000000 { + compatible =3D "ti,j721e-serdes-10g"; + reg =3D <0x0f000000 0x00010000>; + reg-names =3D "torrent_phy"; + resets =3D <&serdes_wiz0 0>; + reset-names =3D "torrent_reset"; + clocks =3D <&serdes_wiz0 TI_WIZ_PLL0_REFCLK>, + <&serdes_wiz0 TI_WIZ_PHY_EN_REFCLK>; + clock-names =3D "refclk", "phy_en_refclk"; + assigned-clocks =3D <&serdes_wiz0 TI_WIZ_PLL0_REFCLK>, + <&serdes_wiz0 TI_WIZ_PLL1_REFCLK>, + <&serdes_wiz0 TI_WIZ_REFCLK_DIG>; + assigned-clock-parents =3D <&k3_clks 279 1>, + <&k3_clks 279 1>, + <&k3_clks 279 1>; + #address-cells =3D <1>; + #size-cells =3D <0>; + #clock-cells =3D <1>; + + status =3D "disabled"; /* Needs lane config */ + }; + }; +}; + +&main_conf { + serdes0_ln_ctrl: mux-controller@4080 { + compatible =3D "reg-mux"; + reg =3D <0x4080 0x4>; + #mux-control-cells =3D <1>; + mux-reg-masks =3D <0x0 0x3>; /* SERDES0 lane0 select */ + }; +}; --=20 2.17.1
