Seems like it should be only 1 of > the rev's at a time. We have added eeprom on SOM and another one on carrier card. And final DT is combination of them. And I wanted to keep track which versions are compatible to each other from software point of view. revB is fully equal to rev1 HW and it is pretty much just change from development version to production version. revA compare to revB has some changes on PCB but still SW compatible. That's why I wanted to keep track of all versions via compatible strings and also Xilinx distribution based on this information creates symlinks to the same DTB to pick up correct DTB based on revision written in eeprom. Also I don't think this is going against compatible string description written in DT spec. "The compatible property value consists of one or more strings that define the specific programming model for the device. This list of strings should be used by a client program for device driver selection. The property value consists of a concatenated list of null terminated strings, from most specific to most general. They allow a device to express its compatibility with a family of similar devices, potentially allowing a single device driver to match against several devices." <snip> >> diff --git a/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revB.dts b/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revB.dts >> new file mode 100644 >> index 000000000000..df054e152a77 >> --- /dev/null >> +++ b/arch/arm64/boot/dts/xilinx/zynqmp-sck-kv-g-revB.dts >> @@ -0,0 +1,318 @@ >> +// SPDX-License-Identifier: GPL-2.0 >> +/* >> + * dts file for KV260 revA Carrier Card >> + * >> + * (C) Copyright 2020 - 2021, Xilinx, Inc. >> + * >> + * Michal Simek <michal.simek@xilinx.com> >> + */ >> + >> +#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-rev1", >> + "xlnx,zynqmp-sk-kv260-revB", >> + "xlnx,zynqmp-sk-kv260", "xlnx,zynqmp"; > > I don't think changing the root compatible in an overlay is a good > policy. Do you need this all to be overlays? Thanks for opening this up. DT overlay is applied in Linux now but in near future we will have to apply it earlier in u-boot. And the main question is if you want to see just SOM board compatible string with k26 or carrier card compatible string (kv260). I choose to rather see carrier card compatible string which is that information which make difference. SOM variants are pretty much the same. The different is only if EMMC is populated or not. Different silicon is also recorded in eeprom but it can be detected and sw is pretty much the same but don't need to be. The boot works in a way that SOM is booting out of QSPI with only DT with SOM description. Then carrier card is detected and DT overlay is applied and never removed. And then in Linux other DT overlays are applied and removed based on application you choose. If you think that my thinking about carrier card compatible string is horribly wrong I have no problem to remove them but I need to find a way how to keep track of carrier revisions which are compatible with this overlay. > >> +}; >> + >> +&i2c1 { /* I2C_SCK C23/C24 - MIO from SOM */ >> + #address-cells = <1>; >> + #size-cells = <0>; >> + pinctrl-names = "default", "gpio"; >> + pinctrl-0 = <&pinctrl_i2c1_default>; >> + pinctrl-1 = <&pinctrl_i2c1_gpio>; >> + scl-gpios = <&gpio 24 GPIO_ACTIVE_HIGH>; >> + sda-gpios = <&gpio 25 GPIO_ACTIVE_HIGH>; >> + >> + u14: ina260@40 { /* u14 */ >> + compatible = "ti,ina260"; > > Not documented.

There are couple of revisions of SOMs (k26) and associated carrier cards (kv260). SOM itself has two major versions: sm-k26 - SOM with EMMC smk-k26 - SOM without EMMC used on starter kit with preprogrammed firmware in QSPI. SOMs are describing only devices available on the SOM or connections which are described in specification (for example UART, fwuen).
