[U-Boot] [PATCH 1/7] arm: socfpga: Allow DWC2 UDC probing from OF

[U-Boot] [PATCH 1/7] arm: socfpga: Allow DWC2 UDC probing from OF

[Marek Vasut]

The USB gadget framework does not support DM yet, so add this bit
to let DWC2 UDC probe from OF on platforms which support it.

[U-Boot] [PATCH 2/7] arm: socfpga: arria5-socdk: Probe DWC2 UDC from OF instead of hard-coded data

[Marek Vasut]

This patch adds the necessary OF alias for the UDC node, which let's
the code locate the DWC2 UDC base address in OF instead of hard-coding
it into the U-Boot binary. The code is adjusted to use the address from
OF instead of the hard-coded one. Finally, the hard-coded address is
removed and USB DM support is enabled.

[U-Boot] [PATCH 6/7] arm: socfpga: sockit: Probe DWC2 UDC from OF instead of hard-coded data

[Marek Vasut]

This patch adds the necessary OF alias for the UDC node, which let's
the code locate the DWC2 UDC base address in OF instead of hard-coding
it into the U-Boot binary. The code is adjusted to use the address from
OF instead of the hard-coded one. Finally, the hard-coded address is
removed and USB DM support is enabled.
