At present, there are no PIO sections inside pinctrl DTS section in constradiction to the same file used in kernel.
This problem causes the pinctrl driver in u-boot to wrongly detect number of pio ports to be zero which in
turn causes the driver to deny any PIO configuration presented in any section of the DTS, for example Ethernet will
not work because of wrong PIO configuration.

Just wanted to tell that I didn’t test the gpio commands in uboot. The part that interested me was the pinctl and that it is unable to set the correct peripheral function from DTS. The function that interested me was Ethernet. I will also check the gpio functionality than I am back to office on Sunday. Thanks!

Indeed, you are correct.With the current code base the pinctrl fails to probe if they are defined inside.

Without the proposed change I was not able to make the Ethernet (EMAC) detect the PHY because MDIO interface was not working - the correct peripheral mode for the EMAC pins was not set as defined in DT.

I confirm that using configuration above, I was not able to make Ethernet (EMAC) in uboot work because it was failing to configure EMAC pins to the required peripheral mode. The at91_pin_check_config function in pinctrl-at91 returned -EINVAL because of nbanks=0. After applying the patch, the Ethernet is working fine. I also confirm that after applying the patch, I was able to toggle IO pin with gpio command (tried PIOC18 which is accessible through IO Connector #1), although I cannot tell you if this functionality also worked before applying the patch.

This suggested modification is a fix-up patch for the pinctrl driver changes present in the uboot-mcho git tree. However, because those changes are not yet present in the mainline U-Boot, this patch will cause regression on all sama5d3 SoC boards. I appreciate your work in finding and resolving the issue for sama5d3.Please hold on to this patch; you can share a version 2 that resolves the comments once the driver changes are in. Also, fyi, this change is already present in the u-boot-mchp tree linux4microchip-2024.10-rc2 version, https://github.com/linux4microchip/u-boot-mchp/commit/a25b31c2558f9fe303a3b97dd660b87476446301 On 22/10/24 11:14 am, Alexey Tsirlin wrote: > EXTERNAL EMAIL: Do not click links or open attachments unless you know > the content is safe > > Hi Manikandan, > > I am using buildroot 2024.04 sama5d3_eds_headless_defconfig config > setup which leads to the following: > 1. uboot from https://github.com/linux4microchip/u-boot-mchp.git > 2. uboot version linux4microchip-2024.10-rc2 3. uboot config > sama5d3_xplained_mmc > > My board is sama5d3 EDS with DP83630 PHY connected to EMAC. > > I confirm that using configuration above, I was not able to make > Ethernet > (EMAC) in uboot work because it was failing to configure EMAC pins to > the required peripheral mode.
