Hi everyone,
In my opinion, use the picozed without a carrier board it doesn't make sense. You always are going to need a carrier board. Avnet has two models the PicoZed FMC Carrier V2 and the PicoZed FMC Carrier V1. And the company I'm working, it is going to desing a custom carrier board according to our necessity.
So maybe, it's better to have only two .dts files. zynq-picozed-fmc-v2.dts and zynq-picozed-fmc-v1.dts.
If we decide to have the zynq-picozed.dtsi and zynq-picozed-fmc-v2.dts, we'll have to decide what hardware description is going to be in the zynq-picozed-fmc-v2.dts and what hardware description is going to be in zynq-picozed.dtsi.
for example the spi0 hw is in the picozed board, but the SD (mmc0), eth0 (gem0) and serial0 (uart1) the HW is in the picoZed but the connectors are in the PicoZed FMC Carrier V2, so It's a little bit confused if this HW description has to be on the zynq-picozed.dtsi file or in the zynq-picozed-fmc-v2.dts file. Do you know what I mean?
Please let me see you opinions about that.
Best regards.

Ok Michal,
Then you're suggesting change the zynq-picozed.dts file to:
dtsi.
diff --git a/arch/arm/dts/zynq-picozed.dts b/arch/arm/dts/zynq-picozed.
dts
index 3408df8..d8ed298 100644 --- a/arch/arm/dts/zynq-picozed.dts +++ b/arch/arm/dts/zynq-picozed.dts @@ -14,6 +14,8 @@
aliases { serial0 = &uart1;
spi0 = &qspi;ethernet0 = &gem0; }; memory {@@ -26,3 +28,18 @@ u-boot,dm-pre-reloc; status = "okay"; };
+&qspi {

keep node names sorted.
+&gem0 {
status = "okay";phy-mode = "rgmii-id";phy-handle = <ðernet_phy>;ethernet_phy: ethernet-phy@0 {reg = <0>;};+};
And add a new dts file with the configuration of the PizoZed FMC Carrier
V2
(in this case V2. Avnet has two PicoZed FMC carriers V1 and V2). For example: zynq-picozed-fmc-v2.dts
- Avnet PicoZed FMC carrier V2 DTS

*/ /dts-v1/;
Depends how zynq-picozed.dtsi will look but this line above can be already there.
#include "zynq-picozed.dts"
/ { compatible = "xlnx,zynq-picozed", "xlnx,zynq-7000";
here "xlnx,zynq-picozed-fmc-v2", "xlnx,zynq-picozed", "xlnx,zynq-7000";
aliases { mmc0 = &sdhci0; }; };
&sdhci0 { u-boot,dm-pre-reloc; status = "okay"; };
Do you think the is the best way?
with changes above it looks reasonable.
Thanks, Michal
