One of my patches in other series which renames the header file will cause issues here :-/ http://lore.kernel.org/r/20210319124128.13308-9-kis...@ti.com We'll need a immutable tag for this as well. > +#include <dt-bindings/phy/phy-ti.h> > + > +/ { > + serdes_refclk: serdes-refclk { > + #clock-cells = <0>; > + compatible = "fixed-clock"; > + clock-frequency = <100000000>; > + }; Clock frequency of serdes_refclk depends on how it is tied in the EVM. In the case of AM64EVM there is no external clock generator. It should be something like in https://github.com/kishon/linux-wip/commit/e5196b0819d334ce8a21b398b7c47557a145d250 Thanks Kishon > +}; > + > &cbass_main { > oc_sram: sram@70000000 { > compatible = "mmio-sram"; > @@ -184,6 +195,12 @@ > reg = <0x4044 0x8>; > #phy-cells = <1>; > }; > + > + serdes_ln_ctrl: mux { > + compatible = "mmio-mux"; > + #mux-control-cells = <1>; > + mux-reg-masks = <0x4080 0x3>; /* SERDES0 lane0 select */ > + }; > }; > > main_uart0: serial@2800000 { > @@ -477,6 +494,41 @@ > }; > }; > > + serdes_wiz0: wiz@f000000 { > + compatible = "ti,am64-wiz-10g"; > + #address-cells = <1>; > + #size-cells = <1>; > + power-domains = <&k3_pds 162 TI_SCI_PD_EXCLUSIVE>; > + clocks = <&k3_clks 162 0>, <&k3_clks 162 1>, <&serdes_refclk>; > + clock-names = "fck", "core_ref_clk", "ext_ref_clk"; > + num-lanes = <1>; > + #reset-cells = <1>; > + #clock-cells = <1>; > + ranges = <0x0f000000 0x0 0x0f000000 0x00010000>; > + assigned-clocks = <&k3_clks 162 1>; > + assigned-clock-parents = <&k3_clks 162 5>; > + > + serdes0: serdes@f000000 { > + compatible = "ti,j721e-serdes-10g"; > + reg = <0x0f000000 0x00010000>; > + reg-names = "torrent_phy"; > + resets = <&serdes_wiz0 0>; > + reset-names = "torrent_reset"; > + clocks = <&serdes_wiz0 TI_WIZ_PLL0_REFCLK>, > + <&serdes_wiz0 TI_WIZ_PHY_EN_REFCLK>; > + clock-names = "refclk", "phy_en_refclk"; > + assigned-clocks = <&serdes_wiz0 TI_WIZ_PLL0_REFCLK>, > + <&serdes_wiz0 TI_WIZ_PLL1_REFCLK>, > + <&serdes_wiz0 TI_WIZ_REFCLK_DIG>; > + assigned-clock-parents = <&k3_clks 162 1>, > + <&k3_clks 162 1>, > + <&k3_clks 162 1>; > + #address-cells = <1>; > + #size-cells = <0>; > + #clock-cells = <1>; > + }; > + }; > + > cpts@39000000 { > compatible = "ti,j721e-cpts"; > reg = <0x0 0x39000000 0x0 0x400>; >
