HW wise they of course exist. revB(development version) is identical with rev1(production version). And there are some HW changes between revA and revB but without impact on SW. That's why all 3 are listed. Board version is recorded in eeprom and based on it the right compatible dt should be taken. > >> + - const: xlnx,zynqmp-sm-k26 >> + - const: xlnx,zynqmp >> + >> + - description: Xilinx Kria SOMs (starter) >> + items: >> + - const: xlnx,zynqmp-smk-k26-rev1 >> + - const: xlnx,zynqmp-smk-k26-revB >> + - const: xlnx,zynqmp-smk-k26-revA >> + - const: xlnx,zynqmp-smk-k26 >> + - const: xlnx,zynqmp >> + >> + - description: Xilinx Kria Carrier Cards (revA/Y/Z) >> + items: >> + - const: xlnx,zynqmp-sk-kv260-revZ >> + - const: xlnx,zynqmp-sk-kv260-revY >> + - const: xlnx,zynqmp-sk-kv260-revA >> + - const: xlnx,zynqmp-sk-k260 >> + - const: xlnx,zynqmp >> + >> + - description: Xilinx Kria Carrier Cards (revB/1) >> + items: >> + - const: xlnx,zynqmp-sk-kv260-rev1 >> + - const: xlnx,zynqmp-sk-kv260-revB >> + - const: xlnx,zynqmp-sk-k260 >> + - const: xlnx,zynqmp >> + >> additionalProperties: true >> >> ... >> diff --git a/arch/arm64/boot/dts/xilinx/Makefile b/arch/arm64/boot/dts/xilinx/Makefile >> index 083ed52337fd..8e43bef2c57e 100644 >> --- a/arch/arm64/boot/dts/xilinx/Makefile >> +++ b/arch/arm64/boot/dts/xilinx/Makefile >> @@ -17,3 +17,13 @@ dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-zcu104-revA.dtb >> dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-zcu104-revC.dtb >> dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-zcu106-revA.dtb >> dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-zcu111-revA.dtb >> + >> +dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-sm-k26-revA.dtb >> +dtb-$(CONFIG_ARCH_ZYNQMP) += zynqmp-smk-k26-revA.dtb >> + >> +som-AA-dtbs := zynqmp-sm-k26-revA.dtb zynqmp-sck-kv-g-revA.dtbo >> +som-AB-dtbs := zynqmp-sm-k26-revA.dtb zynqmp-sck-kv-g-revB.dtbo >> +starter-AA-dtbs := zynqmp-smk-k26-revA.dtb zynqmp-sck-kv-g-revA.dtbo >> +starter-AB-dtbs := zynqmp-smk-k26-revA.dtb zynqmp-sck-kv-g-revB.dtbo >> + >> +dtb-$(CONFIG_ARCH_ZYNQMP) += som-AA.dtb som-AB.dtb starter-AA.dtb starter-AB.dtb >> diff --git a/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revA.dts b/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revA.dts >> new file mode 100644 >> index 000000000000..59d5751e0634 >> --- /dev/null >> +++ b/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revA.dts >> @@ -0,0 +1,335 @@ >> +// SPDX-License-Identifier: GPL-2.0 >> +/* >> + * dts file for KV260 revA Carrier Card >> + * >> + * (C) Copyright 2020 - 2021, Xilinx, Inc. >> + * >> + * SD level shifter: >> + * "A" – A01 board un-modified (NXP) >> + * "Y" – A01 board modified with legacy interposer (Nexperia) >> + * "Z" – A01 board modified with Diode interposer >> + * >> + * Michal Simek <michal.simek@xxxxxxxxxx> >> + */ >> + >> + #include <dt-bindings/gpio/gpio.h> >> + #include <dt-bindings/net/ti-dp83867.h> >> + #include <dt-bindings/phy/phy.h> >> + #include <dt-bindings/pinctrl/pinctrl-zynqmp.h> >> + >> +/dts-v1/; >> +/plugin/; >> + >> +&{/} { >> + compatible = "xlnx,zynqmp-sk-kv260-revA", >> + "xlnx,zynqmp-sk-kv260-revY", >> + "xlnx,zynqmp-sk-kv260-revZ", > > The order above is Z, Y, A.
