[PATCH u-boot-mvebu] arm: mvebu: turris_omnia: Fix ethernet PHY reset gpio FDT fixup
by Marek Behún 30 Apr '24

30 Apr '24

For board revisions where the WAN ethernet PHY reset GPIO is controllable via MCU we currently insert a phy-reset-gpios property into the ethernet controller node. The mvneta driver parses this property and uses the GPIO to reset the PHY. But this phy-reset-gpios property is not a valid DT binding in upstream kernel. Instead, a reset-gpios property should be inserted into the ethernet PHY node. This correct DT binding is supported by the DM ETH PHY U-Boot driver. Insert the reset-gpios property into the WAN PHY node instead the phy-reset-gpios property in WAN ETH node so that Linux will correctly use the reset GPIO. Enable the CONFIG_DM_ETH_PHY config option so that U-Boot will also use the correct DT property. Note: currently there are 4 ethernet controller drivers parsing the wrong DT property: dwc_eth_qos, fex_mxc, mvneta and mvpp2. We should convert all relevant device-trees to use reset-gpios so that we can get rid of these drivers parsing this property.

[PATCH v4 0/3] upstream DT compatibility
by Caleb Connolly 30 Apr '24

30 Apr '24

This is a subset of [1]. With more platform maintainers switching to OF_UPSTREAM I didn't want to get in the way (it has also proven more difficult than I hoped to remove only the fully compatible header files). This series removes only the dt-bindings headers which contain generic data like GPIO flags, input event codes, etc. It then implements support for building all DTBs for a vendor with OF_UPSTREAM_BUILD_VENDOR. This removes the need to maintain a set list of DTBs that can be built by U-Boot and opens up the possibility of new boards becoming supported "by default" just by landing their DT upstream.

[PATCH v4 0/6] Enable ICSSG Ethernet Driver for AM65x
by MD Danish Anwar 30 Apr '24

30 Apr '24

The series introduces device tree and config changes and AM65x to enable ICSSG driver. The series also enables SPL_LOAD_FIT_APPLY_OVERLAY for AM65x in order to load overlay over spl. The ICSSG2 node is added in device tree overlay so that it remains in sync with linux kernel. This series has been tested on AM65x SR2.0, and the ICSSG interface is able to ping / dhcp and boot kernel using tftp in uboot. The users need to set env variables fw_storage_interface, fw_dev_part, fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and partition they want to use to load firmware files from. By default the env fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these envs as per their requirements. This is the v4 of the series [1]. The series doesn't depend on any patch and can be applied cleanly on u-boot/master Changes from v3 to v4: *) Separated the device tree and board specific changes into this series from the main series [1]. *) Added check for TARGET_AM654_A53_EVM config in board file as suggested by Dan Carpenter <dan.carpenter(a)linaro.org> *) Rebased on latest u-boot/master.
