2022-03-09net: phy: Add support for ethernet-phy-id with gpio resetMichal Simek
Ethernet phy like dp83867 is using strapping resistors to setup PHY address. On Xilinx boards strapping is setup on wires which are connected to SOC where internal pull ups/downs influnce phy address. That's why there is a need to setup pins properly (via pinctrl driver for example) and then perform phy reset. I can be workarounded by reset gpio done for mdio bus but this is not working properly when multiply phys sitting on the same bus. That's why it needs to be done via ethernet-phy-id driver where dt binding has gpio reset per phy. DT binding is available here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-phy.yaml The driver is are reading the vendor and device id from valid phy node using ofnode_read_eth_phy_id() and creating a phy device. Kconfig PHY_ETHERNET_ID symbol is used because not every platform has gpio support.

Add support for dynamic configuration which will takes care of configuring the SD secure space configuration registers using firmware APIs, performing SD reset assert and deassert. High level sequence: - Check for the PM dynamic configuration support, if no error proceed with SD dynamic configurations(next steps) otherwise skip the dynamic configuration. - Put the SD Controller in reset. - Configure SD Fixed configurations. - Configure the SD Slot Type. - Configure the BASE_CLOCK. - Configure the 8-bit support. - Bring the SD Controller out of reset. In the above steps, apart from the Fixed configurations, remaining all configurations are dynamic and they will be read from devicetree.

2022-03-08drivers: serial: Make sure we really return a serial deviceMark Kettenis
The stdout-path property in the device tree does not necessarily point at a serial device. On machines such as the Apple M1 laptops where the serial port isn't easy to access and users expect to see console output on the integrated display stdout-path may point at the device tree node for the framebuffer for example. If stdout-path does not point at a node for a serial device, the serial_check_stdout() will not find a bound device and will drop down into code that attempts to use lists_bind_fdt() to bind a device anyway. However, that fallback code does not check that the uclass of the device is UCLASS_SERIAL. So if stdout-path points at the framebuffer instead of the serial device it will return a UCLASS_VIDEO device. Since the code that calls this function expects the returned device to be a UCLASS_SERIAL device, U-Boot will crash as soon as it attempts to send output to the console. Add a check here to verify that the uclass of the bound device really is UCLASS_SERIAL. If it isn't, serial_check_stdout() will return an error and serial_find_console_or_panic() will use the serial device with sequence number 0 as the console and all is fine.
