| * | arm: dts: imx6qdl-u-boot: Alias usb0 to usbotgSjoerd Simons2019-06-111-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All i.mx6 boards seems to have moved to DM_USB, however gadget support for mx6 is still pre-DM as CI_UDC isn't converted yet. To make this work the usb otg controller used for gadgets needs to be usb number 0. Add an alias for this directly in the main u-boot mx6qdl dtsi so it doesn't need to be done for each board separately. This fixes regressions wrt. usb gadget functionality in several boards that have gadget functions enabled in their config, but no usb0 alias in their device-tree.

The bypass configuration means that only XIN will be used, the SoC will not do any driving, and the XIN needs to be provided with a proper signal. This is the MOSCXTBY bit in the PMC main clock generator register. The SPL needs to properly initialize the PMC registers before switching to external clock signal and raising the clock to the cruise speed. Also created Kconfig for this specific configuration. By default this is disabled. Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note that U-Boot is always chainloaded from cboot starting with L4T release 28. cboot always loads U-Boot to a fixed address, so making the builds position independent isn't strictly necessary. However, position independent builds can be convenient because if U-Boot is ever loaded to an address different from its link address, it will still be able to boot.

It does so by first trying to locate the default Ethernet device for the board (identified by the "ethernet" alias) and if found, reads the "local-mac-address" property. If the "ethernet" alias does not exist, or if it points to a device tree node that doesn't exist, or if the device tree node that it points to does not have a "local-mac-address" property or if the value is invalid, it will fall back to the legacy mechanism of looking for the MAC address stored in the "nvidia,ethernet-mac" or "nvidia,ether-mac" properties of the "/chosen" node. The MAC address is then written to the default Ethernet device for the board (again identified by the "ethernet" alias) in U-Boot's control DTB. This allows the device driver for that device to read the MAC address from the standard location in device tree.
