[PATCH] arm64: dts: meson: radxa-zero: allow usb otg mode

[Christian Hewitt]

Setting dr_mode to "host" prevents otg which can be useful on a board
with limited connectivity options. So don't force host mode.

At some point we would need to add the fusb302 node to have proper USB-C PD and mode switch handling.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.3/arm64-dt)

[1/1] arm64: dts: meson: radxa-zero: allow usb otg mode
      https://git.kernel.org/amlogic/c/ce43ea00b927805c1fd0450ccc9b4b6069e292c5

These changes has been applied on the intermediate git tree [1].

The v6.3/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
